Interstate water disputes are as American as apple pie. States often think a neighboring state is using more than its fair share from a river, lake or aquifer that crosses borders.
Currently the U.S. Supreme Court has on its docket a case between Texas, New Mexico and Colorado and another one between Mississippi and Tennessee. The court has already ruled this term on cases pitting Texas against New Mexico and Florida against Georgia.
Climate stresses are raising the stakes. Rising temperatures require farmers to use more water to grow the same amount of crops. Prolonged and severe droughts decrease available supplies. Wildfires are burning hotter and lasting longer. Fires bake the soil, reducing forests' ability to hold water, increasing evaporation from barren land and compromising water supplies.
As a longtime observer of interstate water negotiations, I see a basic problem: In some cases, more water rights exist on paper than as wet water – even before factoring in shortages caused by climate change and other stresses. In my view, states should put at least as much effort into reducing water use as they do into litigation, because there are no guaranteed winners in water lawsuits.

Dry Times in the West
The situation is most urgent in California and the Southwest, which currently face "extreme or exceptional" drought conditions. California's reservoirs are half-empty at the end of the rainy season. The Sierra snowpack sits at 60% of normal. In March 2021, federal and state agencies that oversee California's Central Valley Project and State Water Project – regional water systems that each cover hundreds of miles – issued "remarkably bleak warnings" about cutbacks to farmers' water allocations.
The Colorado River Basin is mired in a drought that began in 2000. Experts disagree as to how long it could last. What's certain is that the "Law of the River" – the body of rules, regulations and laws governing the Colorado River – has allocated more water to the states than the river reliably provides.
The 1922 Colorado River Compact allocated 7.5 million acre-feet (one acre-foot is roughly 325,000 gallons) to California, Nevada and Arizona, and another 7.5 million acre-feet to Utah, Wyoming, Colorado and New Mexico. A treaty with Mexico secured that country 1.5 million acre-feet, for a total of 16.5 million acre-feet. However, estimates based on tree ring analysis have determined that the actual yearly flow of the river over the last 1,200 years is roughly 14.6 million acre-feet.
The inevitable train wreck has not yet happened, for two reasons. First, Lakes Mead and Powell – the two largest reservoirs on the Colorado – can hold a combined 56 million acre-feet, roughly four times the river's annual flow.
But diversions and increased evaporation due to drought are reducing water levels in the reservoirs. As of Dec. 16, 2020, both lakes were less than half full.
Second, the Upper Basin states – Utah, Wyoming, Colorado and New Mexico – have never used their full allotment. Now, however, they want to use more water. Wyoming has several new dams on the drawing board. So does Colorado, which is also planning a new diversion from the headwaters of the Colorado River to Denver and other cities on the Rocky Mountains' east slope.

Utah Stakes a Claim
The most controversial proposal comes from one of the nation's fastest-growing areas: St. George, Utah, home to approximately 90,000 residents and lots of golf courses. St. George has very high water consumption rates and very low water prices. The city is proposing to augment its water supply with a 140-mile pipeline from Lake Powell, which would carry 86,000 acre-feet per year.
Truth be told, that's not a lot of water, and it would not exceed Utah's unused allocation from the Colorado River. But the six other Colorado River Basin states have protested as though St. George were asking for their firstborn child.
In a joint letter dated Sept. 8, 2020, the other states implored the Interior Department to refrain from issuing a final environmental review of the pipeline until all seven states could "reach consensus regarding legal and operational concerns." The letter explicitly threatened a high "probability of multi-year litigation."
Utah blinked. Having earlier insisted on an expedited pipeline review, the state asked federal officials on Sept. 24, 2020 to delay a decision. But Utah has not given up: In March 2021, Gov. Spencer Cox signed a bill creating a Colorado River Authority of Utah, armed with a $9 million legal defense fund, to protect Utah's share of Colorado River water. One observer predicted "huge, huge litigation."
How huge could it be? In 1930, Arizona sued California in an epic battle that did not end until 2006. Arizona prevailed by finally securing a fixed allocation from the water apportioned to California, Nevada and Arizona.
Litigation or Conservation
Before Utah takes the precipitous step of appealing to the Supreme Court under the court's original jurisdiction over disputes between states, it might explore other solutions. Water conservation and reuse make obvious sense in St. George, where per-person water consumption is among the nation's highest.
St. George could emulate its neighbor, Las Vegas, which has paid residents up to $3 per square foot to rip out lawns and replace them with native desert landscaping. In April 2021 Las Vegas went further, asking the Nevada Legislature to outlaw ornamental grass.
The Southern Nevada Water Authority estimates that the Las Vegas metropolitan area has eight square miles of "nonfunctional turf" – grass that no one ever walks on except the person who cuts it. Removing it would reduce the region's water consumption by 15%.
Water rights litigation is fraught with uncertainty. Just ask Florida, which thought it had a strong case that Georgia's water diversions from the Apalachicola-Chattahoochee-Flint River Basin were harming its oyster fishery downstream.
That case extended over 20 years before the U.S. Supreme Court ended the final chapter in April 2021. The court used a procedural rule that places the burden on plaintiffs to provide "clear and convincing evidence." Florida failed to convince the court, and walked away with nothing.

Climate change, activities that contribute to it, and dams pose grave threats to America's rivers, according to American Rivers.
The annual report ranks the county's 10 rivers most endangered by human activity that also have a critical decision point coming in the next year that could change the river's fate.
Four dams are choking the Snake River — earning it the top spot in the report — obstructing salmon and posing an existential threat to Native American tribes in the region who depend on the fish for food, culture and their identities.
Advocates are calling on President Biden to remove the federal dams and revitalize the river and its ecosystem.
Toxic coal ash pollutes the Lower Missouri, which also is experiencing an increase in climate-driven flooding, putting it second on the list, while Iowa's Raccoon River, at number nine, faces threats from industrial agriculture.
Between them are rivers befouled by sewage, polluted or threatened by mining, and otherwise dammed or mismanaged.
"Rivers are among the most degraded ecosystems on the planet, and threats to rivers are threats to human health, safety and survival," American Rivers head Tom Kiernan said.
"If we want a future of clean water and healthy rivers everywhere, for everyone, we must prioritize environmental justice."

The bright patterns and recognizable designs of Waterlust's activewear aren't just for show. In fact, they're meant to promote the conversation around sustainability and give back to the ocean science and conservation community.
Each design is paired with a research lab, nonprofit, or education organization that has high intellectual merit and the potential to move the needle in its respective field. For each product sold, Waterlust donates 10% of profits to these conservation partners.
Eye-Catching Designs Made from Recycled Plastic Bottles
waterlust.com / @abamabam
The company sells a range of eco-friendly items like leggings, rash guards, and board shorts that are made using recycled post-consumer plastic bottles. There are currently 16 causes represented by distinct marine-life patterns, from whale shark research and invasive lionfish removal to sockeye salmon monitoring and abalone restoration.
One such organization is Get Inspired, a nonprofit that specializes in ocean restoration and environmental education. Get Inspired founder, marine biologist Nancy Caruso, says supporting on-the-ground efforts is one thing that sets Waterlust apart, like their apparel line that supports Get Inspired abalone restoration programs.
"All of us [conservation partners] are doing something," Caruso said. "We're not putting up exhibits and talking about it — although that is important — we're in the field."
Waterlust not only helps its conservation partners financially so they can continue their important work. It also helps them get the word out about what they're doing, whether that's through social media spotlights, photo and video projects, or the informative note card that comes with each piece of apparel.
"They're doing their part for sure, pushing the information out across all of their channels, and I think that's what makes them so interesting," Caruso said.
And then there are the clothes, which speak for themselves.
Advocate Apparel to Start Conversations About Conservation
waterlust.com / @oceanraysphotography
Waterlust's concept of "advocate apparel" encourages people to see getting dressed every day as an opportunity to not only express their individuality and style, but also to advance the conversation around marine science. By infusing science into clothing, people can visually represent species and ecosystems in need of advocacy — something that, more often than not, leads to a teaching moment.
"When people wear Waterlust gear, it's just a matter of time before somebody asks them about the bright, funky designs," said Waterlust's CEO, Patrick Rynne. "That moment is incredibly special, because it creates an intimate opportunity for the wearer to share what they've learned with another."
The idea for the company came to Rynne when he was a Ph.D. student in marine science.
"I was surrounded by incredible people that were discovering fascinating things but noticed that often their work wasn't reaching the general public in creative and engaging ways," he said. "That seemed like a missed opportunity with big implications."
Waterlust initially focused on conventional media, like film and photography, to promote ocean science, but the team quickly realized engagement on social media didn't translate to action or even knowledge sharing offscreen.
Rynne also saw the "in one ear, out the other" issue in the classroom — if students didn't repeatedly engage with the topics they learned, they'd quickly forget them.
"We decided that if we truly wanted to achieve our goal of bringing science into people's lives and have it stick, it would need to be through a process that is frequently repeated, fun, and functional," Rynne said. "That's when we thought about clothing."
Support Marine Research and Sustainability in Style
To date, Waterlust has sold tens of thousands of pieces of apparel in over 100 countries, and the interactions its products have sparked have had clear implications for furthering science communication.
For Caruso alone, it's led to opportunities to share her abalone restoration methods with communities far and wide.
"It moves my small little world of what I'm doing here in Orange County, California, across the entire globe," she said. "That's one of the beautiful things about our partnership."

A new study of Greenland's glacial rivers has important implications for how scientists might model future ice melt and subsequent sea level rise.
Previously, researchers thought they could measure ice melt simply by looking at the amount of meltwater sitting on top of glaciers and in moulins — shafts in the glacier that empty rivers from the surface to the interior, Earther explained. But the new study, published in Geophysical Research Letters on Monday, found that a glacier's speed increased when water pressure rapidly changed beneath the ice sheet, NASA explained.
"These findings will help to refine ice sliding models, which are critically important for predicting future ice sheet contributions to global sea level rise," Laurence Smith, study coauthor and Brown University environmental studies professor, told Earther.
The Greenland ice sheet is extremely important when it comes to global sea level rise. The size of Mexico, it currently contributes more to rising sea levels than any other source, NASA reported. If all of Greenland's ice sheet were to melt, it would increase water levels by 20 feet, according to Earther.
"The number one reason we are here is all about global sea level rise," Smith said in a video documenting the research. "Greenland is the single largest melting chunk of ice in the world. What really matters is how much of that water in the ice sheet gets out to the ocean."
To better understand the dynamics driving this melt, Smith and his team traveled to the Russell Glacier in southwestern Greenland in 2016 and studied a glacial river, NASA said. The researchers recorded the forward motion of the glacier itself, the amount of meltwater pouring into the moulin and the amount of meltwater pouring out from beneath the glacier at the water's edge. They determined that changes in subterranean water pressure were driving the glacier's overall speed.
"Even if the cavities are small, as long as the pressure is ramping up very fast, they will make the ice slide faster," Smith explained.
NASA Glaciologist Dr. Lauren Andrews compared a glacier moving over subterranean meltwater to car tires sliding on a wet road.
"If you have a rapid perturbation of water going into the subglacial system, you overwhelm the system, and so you create essentially a layer of water at the interface that's not contained in channels or cavities anymore," Andrews said.
The way that water pressure drives glacier speed had never been studied in the field before, NASA said. This new research now adds 168 hours of "rare in situ" measurements to understand the dynamics of glacial rivers, which had previously been overlooked.
"In 2015 when we started this study, there was surprisingly little attention paid to the hydrology of streams and rivers on the ice sheet, especially inland away from the ice edge, and we felt that this was a critical scientific gap," Smith said in the video.
The research supports the team's initial feeling.
"These findings affirm the importance of supraglacial rivers to subglacial water pressure and ice dynamics, even in relatively thick ice," the researchers wrote.

Atlantic salmon have a challenging life history — and those that hail from U.S. waters have seen things get increasingly difficult in the past 300 years.
Dubbed the "king of fish," Atlantic salmon once numbered in the hundreds of thousands in the United States and ranged up and down most of New England's coastal rivers and ocean waters. But dams, pollution and overfishing have extirpated them from all the region's rivers except in Maine. Today only around 1,000 wild salmon, known as the Gulf of Maine distinct population segment, return each year from their swim to Greenland. Fewer will find adequate spawning habitat in their natal rivers to reproduce.
That's left Atlantic salmon in the United States critically endangered. Hatchery and stocking programs have kept them from disappearing entirely, but experts say recovering healthy, wild populations will require much more, including eliminating some of the obstacles (literally) standing in their way.
Conservation organizations, fishing groups and even some state scientists are now calling for the removal of up to four dams along a 30-mile stretch of the Kennebec River, where about a third of Maine's best salmon habitat remains.
The dams' owner — multinational Brookfield Renewable Partners — has instead proposed building fishways to aid salmon and other migratory fish getting around dams as they travel both up and down the river. But most experts think that plan has little chance of success.
A confusing array of state and federal processes are underway to try and sort things out. None is likely to be quick, cheap or easy. And there's a lot at stake.
"Ultimately the fate of the species in the United States really depends upon what happens at a handful of key dams," says John Burrows, executive director of U.S. programs at the Atlantic Salmon Federation. "If those four projects don't work — or even if just one of them doesn't work — you could basically preclude recovering Atlantic salmon in the United States."
Prime Habitat
The best place for salmon recovery is in Maine's two largest watersheds.
"The Penobscot River and the Kennebec River have orders of magnitude more habitat, production potential and climate resilient habitat" than other parts of the state, says Burrows.
The rivers and their tributaries run far inland and reach more undeveloped areas with higher elevations. That helps provide salmon with the cold, clean water they need for spawning and rearing. Smaller numbers of salmon are hanging on in lower-elevation rivers along the coastal plain in Maine's Down East region, but climate change could make that habitat unsuitable.
"There's definitely concern about how resilient those watersheds are going to be for salmon in the future," says Burrows. "To recover the population, we need to be able to get salmon to the major tributaries farther upriver, in places where we're still going to have cold water even under predictions with climate change."
One of those key places is the Penobscot, which has already seen a $60 million effort to help recover salmon and other native sea-run fish. A 16-year project resulted in the removal of two dams, the construction of a stream-like bypass channel at a third dam, and new fish lift at a fourth. In all, the project made 2,000 miles of river habitat accessible.

While there's still more work to be done on the Penobscot, says Burrows, attention has shifted to the Kennebec. The river has what's regarded as the largest and best salmon habitat in the state, especially in its tributary, the Sandy River, where hatchery eggs are being planted to help boost salmon numbers.
"That's helped us go from zero salmon in the upper tributaries of Kennebec to getting 50 or 60 adults back, which is still an abysmally small number compared to historical counts," says Burrows. "But these are the last of the wildest fish that we have."
The Obstacles
The Sandy may be good salmon habitat, but it's also hard to reach. Brookfield's four dams stand in the way of fish trying to get upriver.
At the lowest dam on the river, Lockwood Dam in Waterville, there's a fish lift — a kind of elevator that should allow fish that enter it to pass up and around the dam. But if fish do find the lift — and only around half of salmon do — they don't get far.
"It's a terminal lift," says Sean Ledwin, division director of Maine's Department of Marine Resources' Sea Run Fisheries and Habitat. "The lift was never completed. So we pick up those fish in a truck and drive them up to the Sandy River."
That taxi cab arrangement isn't a long-term solution, though, and was part of an interim species protection plan.
Only the second dam, Hydro Kennebec, has a modern fish passage system. But how well that actually works hasn't been tested yet since fish can't get by Lockwood Dam. As part of a consultation process related to the Endangered Species Act, Brookfield has submitted a plan proposing to fix the fishway at Lockwood and add passage to the third and fourth dams.
But federal regulators found it inadequate.
"Brookfield's proposal was rejected by the Federal Energy Regulatory Committee [which oversees hydroelectric projects] and all the [federal management] agencies," says Ledwin. The company now has until May 2022 to come up with a new plan.
State scientists aren't convinced Brookfield's plan would work either.
"We have really low confidence that having four fishways would ever result in meaningful runs of all the sea-run fish and certainly not recovery of Atlantic salmon," says Ledwin. "We don't think that it's going to be conducive to recovery."
In addition to considerations related to the Endangered Species Act, Shawmut Dam, the third on the Kennebec, is currently up for relicensing, which triggers a federal review process by FERC.
And at the same time the Maine Department of Marine Resources has drafted a new plan for managing the Kennebec River that recommends removing Shawmut Dam and Lockwood Dam. A public comment period on the proposed plan closed in March.
Brookfield isn't happy with it and responded with a lawsuit against the state.
It was good news to conservation groups, however, which would like to see all four of the dams removed if possible — or at least a few of them.
"There's no self-sustaining population of Atlantic salmon anywhere in the world that we know of that have to go by more than one hydro dam," says Burrows. He believes that having Brookfield spend tens of millions of dollars on new fishways will just result in failure for salmon.

It's partly a game of numbers. Not all fish will find or use a fishway. And if you start with a low number of returning fish and expect them to pass through four gauntlets, you won't be left with many at the end.
"If you're passing 50% of salmon that show up at the first dam, and then you've got three more dams passing 50%, that means you're left with only an eighth of the population you started with by the end," says Nick Bennett, a staff scientist at the Natural Resources Council of Maine. "You can't start a restoration program where you're losing seven-eighths of the adults before they even get to their spawning habitat."
And getting upriver is just part of the salmon's journey. Juvenile salmon face threats going downstream to the ocean as well, including predation and warm water in impoundments. They also risk being injured or killed going through spillways or turbines. Only about half are likely to survive the four hydro projects.
Atlantic salmon, unlike their Pacific cousins, don't always die after spawning, either. So some adults will also make the downstream trek, too.
"Just looking at our reality, at least two dams need to go, hopefully three, and it would be amazing if all four would go," says Burrows.
Ecosystem Restoration
The fate of Atlantic salmon hangs in the balance, but so do the futures of other fishes.
The Pacific coast of the United States is home to five species of salmon. And while the Atlantic side has just the one, it has a dozen other native sea-run species that have also seen their habitat shrink.
"Those dams are preventing other native species like American shad, alewives, blueback herring and American eel from accessing large amounts of historic habitat," says Burrows.
Ledwin says removing dams on the Kennebec could result in populations of more than a million shad, millions of blueback herring, millions of eels and hundreds of thousands of sea lampreys.
"The recovery of those species would actually help Atlantic salmon as well because they provide prey buffers and there are a lot of co-evolved benefits," he says.
Salmon are much more successful at nesting when they can lay their eggs in old sea lamprey nests, explains Bennett. "But sea lamprey are not good at using fish lifts and we've essentially blocked 90% of the historic sea lamprey habitat at Lockwood dam. We need to get those fish upstream, too."
Dam removal advocates don't have to look too far to find an example of how well river ecosystems respond when dams are removed.
The removal of the Edwards Dam on the lower Kennebec River in 1999 and the Fort Halifax Dam just upstream on the Sebasticook in 2008 helped ignite a nationwide dam-removal movement. It also brought back American shad, eel, two native species of sturgeon and millions of river herring to lower parts of the watershed.

"We've got the biggest river herring run in North America now due to the dam removals," says Ledwin. "And the largest abundance of eel we've ever seen on the lower Kennebec."
The resurgence of native fishes helps the whole ecosystem. When they returned, so too did eagles, osprey and other wildlife.
"When people see all those fish in the river and the eagles overhead, it just kind of blows their minds because they never realized what had been lost for so long in our rivers," says Burrows.
Rebuilding key forage fish like herring also benefits species that live not just in the river, but the Gulf of Maine and even the Atlantic Ocean. The tiny fish feed whales, porpoises and seabirds. They're also used for lobster bait and can help rebuild fisheries for cod and haddock, which has economic benefits for the region, too.
"We have to rebalance the scales if we want to have marine industries and commercial fishing industries and if we want the ecological benefits of what sea-run fisheries do for us," says Bennett.
The Path Ahead
The process to determine whether any — or all — of the four Kennebec dams that stretch from Waterville and Skowhegan are removed will take years, a diverse coalition, financial resources and agreements to meet the concerns of communities and the dam owner.
"These things come down to compromise, so there may be situations where one of those dams might not be a candidate for economic or social reasons," says Burrows. "But it will be interesting to see if in the next couple of years we can get to a place where we can have meaningful conversations with federal agencies, the dam owner and continue to engage the communities about the potential of removal at some of these sites."
And if removal of the four dams did happen, it wouldn't open up the river all the way to its headwaters. Another nine dams still lie upstream in the watershed that obstruct fish passage.
"Some of those are major dams in terms of power, production and economics," says Burrows. "So we're not calling for those to be removed."
The four lower dams provide just 46 megawatts of power — enough to supply about 37,000 homes and 0.43% of the state's annual electricity generation. It's a small amount of power relative to the damage they cause sea-run fish, says Bennett.
"By comparison we expect to add 1,200 megawatts of solar generation in the next five years," he says. "So these four dams aren't particularly important in our climate fight." And removing them would open up substantial amounts of habitat to aid salmon recovery that seem worth the tradeoff in lost power.
That's not the case, he says, for the nine larger dams upstream.
"We need those dams. We need hydroelectric power in Maine," says Bennett. "But we made big mistakes in our past use of our rivers. And we went way overboard in favor of hydroelectric power at the expense of fish."
Outside of the rivers, Atlantic salmon still face a tough road. Climate change is warming ocean temperatures, changing salinity and altering food webs. But having so many unknowns in the marine environment in the coming decades provides more reason to focus efforts on restoring rivers where scientists already know what works, says Burrows.
And if that's done right, the benefits will extend far beyond salmon.
"It's not just about salmon — it's about these other native fish, it's about the wildlife, water quality, economic opportunity for ground fishermen and lobstermen, and more sustainable forms of recreation and community development," says Burrows. "If we remove a dam or two here and rebuild these fish populations to pretty big levels that really impacts a whole bunch of different parts of society. That's what we want to try to do here on the Kennebec."

The state of Virginia is taking a stand against single-use plastics.
Gov. Ralph Northam signed an executive order Tuesday designed to phase out the use of non-reusable plastics at state institutions, including colleges and universities. The order comes the same week that Northam signed a law banning polystyrene food containers in the state, as the Richmond Times-Dispatch reported.
"From landmark investments in renewable energy to bold action to tackle the climate crisis, Virginia is at the forefront of innovative efforts to protect our environment, and addressing the problem of plastic pollution is an important part of this work," Northam said in a press release announcing the order. "As a large producer of solid waste, the Commonwealth must lead by example and transition away from single-use disposable plastics to create a cleaner, more sustainable future for all Virginians."
Many plastics are not actually recyclable, as comedian John Oliver detailed just this Sunday in a segment reported on by EcoWatch. In the U.S., less than nine percent of plastics are recycled, while 91 percent end up in landfills or incinerators, according to U.S. Environmental Protection Agency (EPA) statistics. This is a problem in Virginia specifically as well, where the amount of solid waste either burned or landfilled has increased from two million to almost 23 million tons a year since 2011.
To reverse this trend, Northam is requiring all state agencies, colleges and universities to stop the use of unnecessary single-use items within 120 days. These items include plastic bags, food containers, plastic straws and cutlery and water bottles. In addition, state agencies will need to submit plans for phasing out all other non-medical single-use plastics by 2025. There will be short-term exceptions for plastics necessary for medical or public safety uses and long-term exceptions for medical or emergency plastics.
The order was announced as part of the 31st annual Environment Virginia Symposium hosted by the Virginia Military Institute. One of the major concerns about plastics is that they can enter rivers and oceans when improperly disposed of, harming marine life and eventually working their way up the marine food web back to humans. The group Clean Virginia Waterways found that plastic made up 83 percent of the trash found on the state's beaches.
"This bold leadership from Governor Northam's administration to phase out single-use plastic items from the Commonwealth's state agencies and universities will go a long way to setting an example on how to reduce a major source of waste and pollution in Virginia's coastal waters as well as our streams, rivers and agricultural fields," the group's executive director Katie Register wrote in a statement.
In addition to merely phasing out plastics, the order targets solid waste in other ways. It tasks the state Secretary of Natural Resources with investigating ways to keep waste out of landfills period, through measures such as increasing composting and innovative forms of recycling.
"Nobody wants to live next to a landfill, and historically, they have been sited in places that disproportionately impact underserved populations and communities of color," Director of the Department of Environmental Quality David Paylor said in the press release. "This is a significant environmental justice issue, and the less waste we produce, the fewer landfills we will need."
Outside environmental organizations also touted the environmental justice benefits of phasing out plastics.
"Virginia cannot protect the health of Virginians and ensure environmental justice without eliminating its reliance on plastics. Single-use plastics cause long-lasting damage to our environment and waterways and impacts the health of vulnerable communities and people of color the hardest," Sierra Club Virginia Director Kate Addleson said in a statement reported by CBS19. "Executive order 77 is an encouraging first step to combat the issue of plastic pollution at its source. Virginia should continue to embrace policies that phase out SUPs in order to preserve our climate, safeguard our water, and protect the health of Virginians."
To this end, this week also saw the signing of House Bill 533, which mandates the phase-out of all polystyrene food containers by 2025. Virginia follows Maine, Maryland and Vermont in passing such a measure; a New York state ban will also go into effect in 2022, according to the Richmond Times-Dispatch.
"Our leaders have chosen to put the planet over plastic," said Elly Boehmer, state director of Environment Virginia, in a statement responding to the bill's signing.
In a rare occurrence, New York's East River welcomed unexpected visitors on Tuesday — dolphins.
The dolphins were first seen near the WNYC Transmitter Park in Brooklyn around noon, ABC7 reported. Twenty-six-year-old actor and Upper West Side resident Cailin Doran shared videos of the animals on Twitter, Gothamist reported.
Doran, who is originally from California, told Patch that she was used to seeing dolphins in her old home, but not her new one.
"It's just such a bright light in everything that happened over the past year," she said.
While it is unusual to see dolphins with the New York skyline in the background, there are 90 species of whales, dolphins and porpoises that swim in the New York Bight, the estuary between Long Island and New Jersey, Gothamist noted. The New York Department of Environmental Conservation said some of these animals could be seen relatively frequently and others only rarely.
Dr. Howard Rosenbaum, director of Wildlife Conservation Society Ocean Giants Program and New York Aquarium senior scientist, told ABC7 that the dolphins appeared to be common dolphins, which would make Tuesday's East River sighting all the more unusual.
"We see these animals during our offshore surveys in the wider New York Bight — so this is not normally where they are seen," Rosenbaum told ABC7. "In the New York Harbor and surrounding estuary, we actually have detected two other species — bottlenose dolphins and harbor porpoise — from a two acoustic monitoring study we recently completed."
Rosenbaum told Gothamist that the dolphins were probably following prey. However, it can be dangerous for dolphins to enter the East River if they swim into certain areas. For example, a dolphin died in 2013 after swimming into the highly polluted Gowanus Canal and getting stuck there, Gothamist reported at the time.
"Hopefully, this is a group of animals that has been able to freely swim into this area and will freely swim out of the area and are not in distress," Rosenbaum told Gothamist.
The waterways around New York City have generally become more hospitable for marine life. ABC7 reported that humpback whales were spotted in the Hudson River in 2016 and 2020, which the Parks Department possibly credited to improved water quality and an abundance of food. A 2017 report from the NYC Department of Environmental Protection revealed that the harbor's water quality had reached the healthiest level in more than a century.
"Over the past decade, the City has invested more than $12 billion to upgrade the sewer system and wastewater treatment plants to improve the health of these critical ecosystems," Commissioner Vincent Sapienza wrote in the report. "This investment, over time, has produced many ecological successes, ushering in the return of a variety of plant and animal species to our waters — including whales!"
And, it would appear, dolphins.
A seal that had won the hearts of West London had to be put to sleep after a dog attack Sunday.
The 10-month-old harbor seal, nicknamed Freddie Mercury, was taken to the South Essex Wildlife Hospital, where staff discovered he had a fractured flipper and dislocated joint, the hospital wrote on Facebook. They also said he was not eating and had a spreading infection.
"At this stage we believe the only ethical and fair option we have is to end his suffering," the hospital wrote.
Freddie first gained public fame in February after being rescued from the Teddington Lock in Southwest London, where he got a fishing lure stuck in his mouth, The Guardian reported. He was released on the Isle of Sheppey off the Kent coast, but returned to the Teddington stretch of the Thames to Londoners' delight.
'We are so lucky to have these beautiful animals in our river, it's magical," Broni Lloyd-Edwards, a photographer whose images of Freddie appeared in Metro, told the paper.
However, a dog mauled Freddie as he basked along the riverside on Sunday, The Guardian reported. Four people rushed to pry open the dog's jaws, including a vet. The dog and its owner then left, while emergency workers from the British Divers Marine Life Rescue (BDMLR) rushed the seal to the hospital.
In a Facebook post, BDMLR concurred that nothing more could be done for Freddie.
"Freddie was a wild seal and after the ferocious attack on Sunday he suffered a serious broken and dislocated flipper," BDMLR CEO Alan Knight wrote on Facebook. "We contacted one of the UK's leading orthopedic surgeons, and he said that unfortunately the only option was to euthanize the seal."
Both the hospital and BDMLR said the incident underscored the importance of giving wildlife the space they need.
"Sadly, Freddie is not the only seal we have had to care for that this has happened to," the hospital wrote. "Please folks do not go near seals and always, always, keep dogs on leads and under control."
BDMLR agreed.
"We are all absolutely gutted to hear about the extent of the injuries Freddie suffered, and highlights yet again the serious problems that can arise when humans and dogs encounter wild animals," the group wrote. "We hope that his story will go a long way to helping educate people to look up and follow the appropriate guidelines for how to behave respectfully around wild animals and not cause disturbance or worse to them."
This could be life-saving advice for the harbor seals that frequent the Thames. The Zoological Society of London's Thames Marine Mammal Survey has so far reported 117 seal sightings along the river this year, the Evening Standard reported.
"It is not unusual for seals to find their way into harbors or rivers such as the Thames and they have been known to travel inland quite some distance," a spokesperson for the Royal Society for the Prevention of Cruelty to Animals told Metro. "They are often just looking for more food and generally they find their way out to sea again."

It's not too hard to find salmon on a menu in the United States, but that seeming abundance — much of it fueled by overseas fish farms — overshadows a grim reality on the ground. Many of our wild salmon, outside Alaska, are on the ropes — and have been for decades.
Twenty years ago Pacific salmon were found to have disappeared from 40% of their native rivers and streams across Oregon, Washington, Idaho and California. In places where they remain, like the Columbia River system, the number of wild fish returning to streams is estimated to have plunged by as much as 98%. Today 28 populations of West Coast salmon and steelhead are listed as threatened or endangered under the Endangered Species Act.
New research is helping to put the problem — and solutions — into focus. But in some cases, policy to implement changes still lags.
1. Trouble in Washington
With 14 salmon and steelhead species listed as endangered in Washington, a new report by the state declared that "too many salmon remain on the brink of extinction. And time is running out." Four key factors, the researchers say, have been attributed to their historical decline: habitat, harvest, hydropower and hatcheries.
2. Upstream Changes
Along with historic threats, there's another new factor making salmon recovery challenging for Washington and other West Coast states: climate change. Increasing temperatures are causing snowpack declines, resulting in warmer streams that can stress or kill salmon. Additionally, more precipitation falling as rain instead of snow causes rivers to run faster earlier in the season, which can wash away salmon nests and sweep young salmon out of their calm-water habitat before they're ready — reducing their chances of survival.
3. Ocean Woes
It's not just freshwater habitat for salmon that's changing. A recent study in the journal Communications Biology looked at how eight populations of wild spring-summer Chinook from the Snake River Basin fared during the ocean phase of their lives. And it's not good. If ocean warming continues, by the 2060s mortality for Chinook could be as high as 90%.
4. Ripple Effect
Pacific salmon are an integral cultural resource for Pacific Northwest tribes and provide thousands of regional jobs. But the fish don't just feed people. They also nourish freshwater and marine ecosystems, along with more than 100 species.
And for one animal in particular, the critically endangered Southern Resident killer whale (Orcinus orca), the decline of Chinook is an existential threat. It's been long known that Southern Residents feed primarily on Chinook — the largest Pacific salmon species — during the summer. But a new study published in the journal Plos One found that Chinook were also important year-round.

5. Implementing Solutions
In an effort to help the recovery of Southern Residents and help boost salmon populations in the region, conservation groups have increased their calls to remove four dams on the Lower Snake River, a major tributary of the Columbia River in Washington.
While the science supports dam removal to save salmon, putting that into action has run into a wall of political opposition — mostly from conservatives. However, a recent plan proposed by Idaho Rep. Mike Simpson to breach the Snake River dams was a rare showing of Republican support, which could signal more bipartisan efforts ahead.
Other dam removals — both large and small — have proved beneficial for salmon in Washington and other states. In California a groundbreaking project to allow rivers to flood fallow farm fields in winter has helped provide both food and rearing habitat for salmon — and has helped prove that water managers don't have to choose between fish and farmers.

The only thing "new" about West Virginia's New River Gorge is its national park status: In 2021, the New River Gorge became our latest national park, but in geologic terms, the New River is anything but new. Dating back to the days of the supercontinent Pangaea, it is one of the oldest rivers in the world and one of the few waterways in North America that runs north.
A lot can happen when a river keeps its course for over 300 million years. The New River's unusual north–south orientation serves as a corridor for animal migration, fueling a biodiversity hot spot that is home to an impressive array of endemic species, many of them endangered.
Millions of years of fluvial erosion have also carved a deep gorge lined by long tracts of bituminous coal and steep cliffs of quartzite sandstone. In the late 1800s, dozens of coal mines and company towns were built along the New's raging river canyon, accessible only by railroad. Today their vine-covered ruins are being reclaimed by the regenerating forest, and the ecological impacts of mining and deforestation on the New River's watershed are slowly healing.
A mere 30 kilometers from the New, however, deep scars blasted into the landscape by modern mountaintop removal mining operations may prove more or less permanent, even on geologic timescales.
New River, Old Course
"The New River might be the most inappropriately named river on Earth," said Nathaniel Hitt, a fish biologist with the U.S. Geological Survey in Kearneysville, W.Va.
The New was born when the North American and African plates collided to form the supercontinent Pangaea. The impact uplifted the Appalachian Mountains to Himalayan heights, and a mighty river named the Teays formed to drain the western slopes of the range. From its headwaters in what is now western North Carolina, the Teays flowed north through the Virginias before turning west into the Ohio River Basin, eventually draining into a vast inland sea.
Today the New River begins in the same headwaters carved by the Teays and follows roughly the same northward path. "These headwaters and this basin have remained in their current configurations for over 300 million years of evolutionary time," Hitt said.
Around 60 million years ago, the diagonally trending ridges of the Appalachians went through a period of uplift, but the highly erosive Teays kept cutting into the mountains faster than the uplift rate. Thus, the river's south-to-north course runs counter to the west-to-east flow of most Appalachian waterways, carving a formidable 400-meter-deep river canyon directly through the Appalachian Plateau.
The 580-kilometer-long New River carves the longest and deepest canyon in the Appalachian Mountains; the new 295-square-kilometer national park and preserve is headquartered along an 85-kilometer stretch of the river near Fayetteville, W.Va.
A Speciation Superhighway
Downstream—to the north—the New joins the Gauley to form the Kanawha River. Just downstream from this confluence, the wide and turbulent Kanawha Falls present a natural barrier to migration, leading to many aquatic species above and below the falls being genetically distinct from one another.
For instance, "when you look at the fish of the New River, you're seeing how evolution plays out over long geologic timescales," Hitt said. "The New River highlights the potential of deep evolutionary time to produce uniquely adapted species." The New River Basin is home to seven endemic species of fish—fish that are found nowhere else on Earth. These fish are uniquely adapted to thrive in turbulent white water and have lived through several major extinction events and an ice age that froze the northern reaches of their habitat.
The New's deep canyons also function as a biogeographical corridor for terrestrial animals, facilitating north–south movement in a landscape where most valleys run east–west. The New River Gorge's unusual orientation "lies at the core of one of the largest intact temperate forests in the world," said Douglas Manning, a terrestrial ecologist at the national park. "The gorge has a lot of niche habitats for different organisms to occupy," supporting a diverse assemblage of plants, mammals, birds, and aquatic species.
Whereas the New River allows for north–south migration, its steep and rugged topography presents a significant barrier to east–west movement. Historically, even humans have found the New a formidable obstacle. The turbulent waters are not safe for most river-based transportation, and steep cliffs can impede navigation on foot or horseback.
Although people have been living in southern West Virginia for at least 11,000 years, the main travel routes of early Indigenous communities "were not through the gorge, because it's so circuitous and dangerous to travel along the river," said Dave Fuerst, cultural resource program manager for the park. "They were using routes that went around the gorge, following ridges and stream drainages." Communities thrived in the ecologically rich area, however, and today more than 400 archaeological sites are documented along the New, Gauley, and Bluestone Rivers, connected by an elaborate network of footpaths.
It wasn't until the completion of the Chesapeake and Ohio (C&O) Railway in 1873 that people were able to travel the length of the gorge efficiently. Even then, east–west travel across the gorge remained harrowing until 1977, when the New River Gorge Bridge was completed just east of Fayetteville, shortening the cross-gorge travel time from over an hour to less than a minute. This impressive 923-meter-long steel arched span soars 267 meters above the New, making it one of the highest vehicular bridges in the world.
Coal Mining in My Mitochondria
The rock layers exposed by the New River span over 350 million years. Historically, the most sought-after layers in the gorge were bituminous coal, a relatively soft black coal that burns readily, producing little smoke. These layers date to the Pennsylvanian subperiod of the Carboniferous, when vast swamps covered large regions of the globe, producing thick layers of peat that eventually formed coal.

The downward cutting of the New River did a lot of the work to expose bituminous coal seams along the gorge. After the C&O railroad was finished, dozens of coal mines sprang up along the New. From the late 1800s to the mid-1900s, miners hacked millions of tons of coal from the walls of the gorge. The work was brutal, and the pay was around 45 cents a ton. Strong miners could earn $2.00 a day.
For a time, New River coal was one of the most abundant on the market, fueling everything from steel mills to power plants. More than 60 coal towns were built along the New River to support the mines. Some of these towns boasted hundreds of buildings and were home to thousands of people.

In the late 1800s and early 1900s, dozens of coal company mining towns were built along the New River. All of the railroad-accessed towns were abandoned by the 1960s. Coalcampusa.com.
My family history runs deep in these New River mining towns: The town of Caperton was named for one of my relatives, my maternal great-grandmother was born in Fire Creek, and my paternal grandparents lived and worked in Ames, where New River Gorge Bridge pylons now stand on the east side of the gorge. When my dad was 2 years old, the family moved to Fayetteville, on the west side of the gorge, where my uncle still lives in the family home.
I spent the summers of my childhood exploring the woods and creeks around the gorge, hunting for salamanders and seashell fossils from a long-gone ocean that predates the Appalachians. Every time I visit the New, I feel like a salmon returning to its home stream; I imagine my great-grandmother's mitochondria in my cells vibrating in tune with one of the world's oldest rivers. I've hiked all over the New River Gorge, visiting the overgrown sites and ruins of Ames, Kaymoor, and Nuttallburg, but I have not yet made it farther upriver to Caperton or Fire Creek. Someday an anadromous upriver backpacking trip awaits (although I have no plans to spawn).
Making the Leap from Coal Mining to BASE Jumping
All of the mines and coal towns in the New River Gorge were abandoned by the 1960s, and today the still-inaccessible ghost towns are fading into the rapidly regenerating forest.
"The New River Gorge faces a lot of legacy impacts from all sorts of land use history in the gorge," Manning said. Vast areas of forest were stripped of trees to fuel the coal towns' woodstoves and coke ovens, and timber operations in the gorge continued for decades after mining operations ceased.
"If you look at photos from around the turn of the century and the Great Depression, [you will see that] the forest here was stripped bare," said Eve West, chief of interpretation at the New River Gorge National Park and Preserve. And now, "this is considered to be the most botanically diverse river system in the central and southern Appalachians. There's not a lot of virgin forest here, so that's all come from regrowth in the past 50 years. This place bounces back fast."
Regrowth and resiliency are proving to be a hallmark of this landscape and for its people. Two generations removed from the dark and dangerous coal mines, I find myself drawn upward, to the New River's second most famous rock: Nuttall sandstone, a hard, quartz-rich variety that erodes into vertical cliffs with thin cracks perfect for rock climbing.
More than 1,400 traditional and sport climbing routes snake up the walls of the gorge, making it one of the premiere climbing localities in the eastern United States. I cut my teeth on these rocks in more ways than one; in 2008, fresh out of graduate school with a newly minted master's degree in science journalism, one of my very first assignments was to cover the New River Rendezvous, an annual 3-day rock climbing festival in the gorge, for Climbing magazine.
I have not yet rafted the raging rapids of the highly technical New River. Even after braving 22 glorious days rafting the Colorado River through the Grand Canyon, I am still intimidated by the New's legendary hydraulics.
I have even less desire to try the gorge's other adrenaline-fueled sport: BASE (buildings, antennas, spans, and Earth) jumping from the New River Gorge Bridge into the river, 267 meters below. Watching dozens of people eagerly leap from the dizzying span on Bridge Day is enough of a rush for me.
The New River's potential as an adventurer's paradise is still expanding, with new mountain biking and hiking trails added every year. In 2019, around 1.3 million people recreated at the New, and tourism now drives Fayetteville's once-faltering economy. "The New River Gorge is a fascinating place—geologically, ecologically, and historically—in a majestic setting," Hitt said. "I hope people will be inspired by this elevated [national park] designation to come visit."
We All Live Downstream
The New River Gorge National Park and Preserve encompasses almost 295 square kilometers of land around the river corridor, but the New River's entire watershed is more than 18,000 square kilometers. "One of the ongoing challenges is that we can protect and manage the gorge itself, but we don't own the headwaters upstream," where the river is "undoubtedly" still affected by ongoing mining, Manning said.
The New River's upstream watershed includes mountaintop removal mining, in which the tops of entire mountains are removed to access buried coal seams, and the overburden is pushed into a neighboring valley, destroying thousands of kilometers of mountain streams. Across southern West Virginia, 1.5 million acres of land have been affected by mountaintop removal mining operations, which have buried more than 3,200 kilometers of streams in rubble, a tactic called valley fill.
As groundwater trickles through the jumbled subsurface of a valley fill, it picks up minerals, metals, and salts from the debris, increasing the salt and mineral content of the water downstream. A 2014 study by Hitt and colleagues in Freshwater Science found "fewer species, lower abundances, and less biomass" downstream from mining operations.
Trees seem to be the key in kick-starting the healing process. "We've found that restoring trees to the postmining landscape helps restore the hydrologic function" within a matter of years to decades, said Chris Barton, a forest hydrologist at the University of Kentucky in Lexington. Trees pull a lot of water out of the groundwater system, keeping it from mobilizing minerals, salts, and pollutants.
"As the forest regrows, we're seeing a return to the natural hydrology of these sites, along with improvements in the water quality that [are] needed to support aquatic life," Barton said.
One reforestation project, at a former mountaintop removal mine that was replanted in 2009, went from looking like "the surface of the Moon" to a lush green forest in less than a decade, Barton said. Last year, Barton observed minnows in the stream he and his team created out of the moonscape of rubble.
New, Forever
Even with restoration and reforestation, the scars left on the landscape by mountaintop removal mining are permanent, Barton said. "Reforesting helps hide the scars, but they're still there. I do wonder about how erosion over geologic timescales will work on those valleys filled with loose, unconsolidated rock," he said. "It seems likely they will erode much faster than the mountains themselves" and may result in deep gorges and holes in the landscape.
In terms of pollution, the legacy of mining in Appalachia will linger essentially forever, said Margaret Palmer, a restoration ecologist at the University of Maryland. "Replanting offers the best hope for restoring stream biodiversity, but no matter what you do, it's crystal clear that mining poisons streams and that mined land will continue to release toxins into the ecosystem in perpetuity."
With a 300-million-year history, the New is no stranger to perpetuity. The river's deeply entrenched course is likely to stay that way for eons longer, perhaps until the North American continent is reconfigured into a new landmass in a few hundred million years. The New's steady presence may prove crucial to plant and animal species as climate change progresses, Manning said, because species are projected to migrate north in response to warming temperatures.
"The New represents one of the most direct avenues for species migration in the Appalachian Mountains," he said. "In the future, I can see the New River Gorge harboring species on their northward migration. I think we'll see how important and resilient the forests of the Appalachians really are, as landscapes and climate continue to change."

It makes up the concrete of our houses, the tarmac of our roads, the glass in our windows and the silicon chips in our phones.
But sand, a building block of modern life that sits at the heart of a destructive and sometimes illegal industry, is in increasingly short supply — and nobody knows how soon it will run out.
Sand is the most used material on the planet but also one of the least well monitored. Unlike most other commodities, policymakers only have rough estimates of how much of it is used each year. A landmark report from the UN Environment Program (UNEP) in 2019 had to rely on data for cement — which sand and gravel are mixed with to make concrete — to land on a ballpark figure of 50 billion tons.
Researchers say that's more sand than can be responsibly used each year, even though more sand can be made by crushing rocks. In some regions, the shortages have already fueled targeted killings and the destruction of habitats.
"The nature of the crisis is we don't understand this material well enough," said Louise Gallagher from the Global Sand Observatory in Geneva, who co-authored the report. "We don't understand the impacts enough of where we're taking it from. Sometimes we don't even know where it's coming from, how much is coming out of rivers. We don't know. We just don't know."
Extracting Sand
What experts do know, though, is that extracting sand in unparalleled quantities comes at a growing cost to people and the planet.
Sand mining destroys habitats, dirties rivers and erodes beaches, many of which are already losing ground to rising sea levels. When miners dig out layers of sand, riverbanks become less stable. The pollution and acidity can kill fish and leave less water for people and crops. The problem is made worse when dams upstream prevent sediments from replenishing the river.
"It has so many other impacts that are not taken into consideration," said Kiran Pereira, an independent researcher who has written a book on solutions to the sand crisis. "It's definitely not reflected in the cost of sand."
Worse, much of the impact may not be immediately visible, which makes it hard to know exactly how bad it is, said Stephen Edwards, who leads research on extractive industries at the International Union for the Conservation of Nature (IUCN). "It certainly is something that is rising to a level that we really need to be paying closer attention to."
According to an article published in the journal Nature in 2019, sand mining has helped push fish-eating gharial crocodiles in the Ganges river to the brink of extinction — fewer than 250 adults remain in the wild — and destabilized riverbanks in the Mekong whose collapse could force half a million people from their homes.
One reason the damage from mining has been ignored is that although sand is in objects all around us, it's "hidden in plain sight," said Chris Hackney, a geographer at the University of Newcastle in the UK, who studies the issue and co-authored the Nature article. "Ask people to name the most important commodity on the planet and sand is probably not the one that gets mentioned."
Concrete Boom
Sand shortages even sound counterintuitive. Although one-third of the Earth's land surface is classified as desert, much of it sandy, Middle Eastern countries like Saudi Arabia import sand from as far away as Canada and Australia. The 830m-tall Burj Khalifa, a skyscraper in the neighboring United Arab Emirates, was built using imports from the other side of the world.
This is because desert sand holds little value for the construction industry.
When winds blow over dunes, they shape sand particles into spheres. These round balls have less grip than the jagged grains found on riverbeds, beaches and sea floors, which have the friction needed to make concrete strong.
"As I grew up in Bangalore, I constantly read reports about the rivers being decimated due to sand mining," said Pereira, the researcher, adding that some of her earliest memories involve waking up at 2:00 a.m. to fetch water from a crowded public tap. "At the same time, I remember seeing hundreds and hundreds of trucks filled with sand flying up and down the roads, supplying all the construction sites."
Most of the demand comes from China, which made more cement in the three years from 2011 to 2014 than the U.S. did in the entire last century. India, the next-biggest cement producer, is projected to overtake China as the world's most populous country by 2027.
As people across Asia and Africa move to cities and the world population swells to 10 billion people by the middle of the century, demand for sand is projected to keep rising.
And it's not just for making concrete. In 2011, 20 million cubic meters of sand was dredged from the sea floor on the coasts of the Netherlands to form a natural barrier protecting against erosion and climate change. Over the last half century Singapore has built artificial islands that have increased its land mass by a quarter using sand imported from Cambodia, Vietnam, Indonesia and Malaysia. Dubai's artificial Palm Islands, visible from space, were made with sand dredged from the bottom of the Persian Gulf.
Sand Mafias
And then there's the human cost.
As sand prices have risen, police officers in countries from South Africa to Mexico have kept reporting dead bodies at the hands of miners.
Nowhere is the violence worse than in India, home to the world's deadliest "sand mafias." Criminal gangs there have burned journalists alive, hacked activists to death and run over police officers with trucks. A report last year from the South Asia Network on Dams, Rivers and People, an environmental group based in Delhi, counted 193 people who died through illegal sand mining in India over the last two years. The main causes of death were poor working conditions, violence and accidents.
While some miners dive to the bottom of rivers hundreds of times a day without protective clothing, and there are reports of child labor from India to Uganda, their employers are rarely held accountable.
That partly changed in late February, when a special court in Delhi jailed the boss of India's largest sand mining company, V.V. Minerals, and a former director of the environment ministry for bribery. The mining baron, who has denied allegations of illegal sand mining that stretch back decades, had been caught paying the university tuition fees of an official's son in exchange for an environmental clearance, in a case that one local news outlet compared to notorious American mobster Al Capone being jailed for tax violations.
To solve the sand crisis, experts say world leaders need to better regulate the industry and enforce laws against corruption, as well as monitoring global sand production. They would need to cut demand for sand by finding alternatives to concrete and building more efficiently with materials like timber. The waste from demolished buildings could be reused as aggregate for roads, for instance.
Some researchers are exploring ways to make the world's abundant desert sand suitable for building, by heating and crushing the grains, and are now looking to make the processes cheap enough to be practical.
"Our ability to construct does not depend on our need for sand," said Pereira. "We can decouple these two and still build and allow for human prosperity without destroying our ecosystem."

There's some good news amidst the grim global pandemic: At long last, the world's largest dam removal is finally happening.
The landmark agreement, which was finalized in November 2020 between farmers, tribes and dam owners, will finally bring down four aging, inefficient dams along the Klamath River in the Pacific Northwest. This is an important step in restoring historic salmon runs, which have drastically declined in recent years since the dams were constructed. It's also an incredible win for the Karuk and Yurok tribes, who for untold generations have relied on the salmon runs for both sustenance and spiritual well-being.
The tribes, supported by environmental activists, led a decades-long effort to broker an agreement. They faced vehement opposition from some farmers and owners of lakeside properties, but in 2010, they managed what had seemed impossible: PacifiCorp, the operator of the dams, signed a dam removal agreement, along with 40 other signatories that included the tribes and the state governments of Oregon and California. Unfortunately, progress stalled for years when questions arose around who would pay for the dam removals.

A team of campaigners and lawyers from EarthRights International joined Indigenous Karen communities on the Salween in 2018 to celebrate the International Day of Actions for Rivers on March 14.

The dam removal project is a sign of the decline of the hydropower industry, whose fortunes have fallen as the troubling cost-benefit ratio of dams has become clear over the years. The rise of more cost-effective and sustainable energy sources (including wind and solar) has hastened this shift. This is exactly the type of progress envisioned by the World Commission on Dams (WCD), a global multi-stakeholder body that was established by the World Bank and International Union for Conservation of Nature in 1998 to investigate the effectiveness and performance of large dams around the world. The WCD released a damning landmark report in November 2000 on the enormous financial, environmental and human costs and the dismal performance of large dams. The commission spent two years analyzing the outcome of the trillions of dollars invested in dams, reviewing dozens of case studies and testimonies from over a thousand communities and individuals, before producing the report.
But despite this progress, we cannot take hydropower's decline as inevitable. As governments around the world plan for a post-pandemic recovery, hydropower companies sense an opportunity. The industry is eager to recast itself as climate-friendly (it's not) and secure precious stimulus funds to revive its dying industry — at the expense of people, the environment and a truly just, green recovery.
Hydropower’s Troubling Record
The world's largest hydropower dam removal project on the Klamath River is a significant win for tribal communities. But while the Yurok and Karuk tribes suffered terribly from the decline of the Klamath's fisheries, they were by no means alone in that experience. The environmental catastrophe that occurred along the Klamath River has been replicated all over the world since the global boom in hydropower construction began early in the 20th century.
The rush to dam rivers has had huge consequences. After decades of rampant construction, only 37 percent of the world's rivers remain free-flowing, according to one study. River fragmentation has decimated freshwater habitats and fish stocks, threatening food security for millions of the world's most vulnerable people, and hastening the decline of other myriad freshwater species, including mammals, birds and reptiles.
The communities that experienced the most harm from dams — whether in Asia, Latin America or Africa — often lacked political power and access. But that didn't stop grassroots movements from organizing and growing to fight for their rights and livelihoods. The people affected by dams began raising their voices, sharing their experiences and forging alliances across borders. By the 1990s, the public outcry against large dams had grown so loud that it finally led to the establishment of the WCD.
What the WCD found was stunning. While large dam projects had brought some economic benefits, they had also forcibly displaced an estimated 40 to 80 million people in the 20th century alone. To put that number into perspective, it is more than the current population of present-day France or the United Kingdom. These people lost their lands and homes to dams, and often with no compensation.
Subsequent research has compounded that finding. A paper published in Water Alternatives revealed that globally, more than 470 million people living downstream from large dams have faced significant impacts to their lives and livelihoods — much of it due to disruptions in water supply, which in turn harm the complex web of life that depends on healthy, free-flowing rivers. The WCD's findings, released in 2000, identified the importance of restoring rivers, compensating communities for their losses, and finding better energy alternatives to save rivers and ecosystems.
Facing a New Crisis
Twenty years after the WCD uncovered a crisis along the world's rivers and recommended a new development path — one that advances community-driven development and protects freshwater resources — we find ourselves in the midst of another crisis. The global pandemic has hit us hard, with surging loss of life, unemployment and instability.
But as governments work to rebuild economies and create job opportunities in the coming years, we have a choice: Double down on the failed, outdated technologies that have harmed so many, or change course and use this transformative moment to rebuild our natural systems and uplift communities.
There are many reasons to fight for a green recovery. The climate is changing even faster than expected, and some dams — especially those with reservoirs in hot climates — have been found to emit more greenhouse gases than a fossil fuel power plant. Other estimates have put global reservoirs' human-made greenhouse gas emissions each year on par with Canada's total emissions.
Meanwhile, we now understand that healthy rivers and freshwater ecosystems play a critical role in regulating and storing carbon. And at a time when biodiversity loss is soaring, anything we can do to restore habitat is key. But with more than 3,700 major dams proposed or under construction in the world (primarily in the Global South, with over 500 of these in protected areas), according to a 2014 report — and the hydropower industry jockeying for scarce stimulus dollars — we must act urgently.
Signs of Hope

So what would a strong, resilient and equitable recovery look like in the 21st century? Let's consider one example in Southeast Asia.
Running through six countries, the Mekong River is the world's 12th-longest river, which is home to one of the world's most biodiverse regions, and includes the world's largest inland fishery. Around 80 percent of the nearly 65 million people who live in the Lower Mekong River Basin depend on the river for their livelihoods, according to the Mekong River Commission. In 1994, Thailand built the Pak Mun Dam on a Mekong tributary. Six years later, the WCD studied the dam's performance and submitted its conclusions and recommendations as part of its final report in 2000. According to the WCD report, the Pak Mun Dam did not deliver the peaking energy service it was designed for, and it physically blocked a critical migration route for a range of fish species that migrated annually to breeding grounds upstream in the Mun River Basin. Cut off from their customary habitat, fish stocks plummeted, and so did the livelihoods of the local people.
Neighboring Laos, instead of learning from this debacle, followed in Thailand's footsteps, constructing two dams on the river's mainstem, Xayaburi Dam, commissioned in 2019, and Don Sahong Dam, commissioned in 2020. But then a sign of hope appeared. In early 2020, just as the pandemic began to spread across the world, the Cambodian government reconsidered its plans to build more dams on the Mekong. The science was indisputable: A government-commissioned report showed that further dams would reduce the river's wild fisheries, threaten critically endangered Irrawaddy dolphins and block nutrient-rich sediment from the delta's fertile agricultural lands.
Studies show that Cambodia didn't need to seek billions of dollars in loans to build more hydropower; instead, it could pursue more cost-effective solar and wind projects that would deliver needed electricity at a fraction of the cost — and without the ecological disasters to fisheries and the verdant Mekong delta. And, in a stunning reversal, Cambodia listened to the science — and to the people — and announced a 10-year moratorium on mainstream dams. Cambodia is now reconsidering its energy mix, recognizing that mainstream hydropower dams are too costly and undermine the economic and cultural values of its flagship river.
Toward a Green Recovery

Increasingly, governments, civil servants and the public at large are rethinking how we produce energy and are seeking to preserve and restore precious freshwater resources. Dam removals are increasing exponentially across North America and Europe, and movements advancing permanent river protection are growing across Latin America, Asia and Africa.
We must use the COVID-19 crisis to accelerate the trend. Rather than relying on old destructive technologies and industry claims of newfound "sustainable hydropower," the world requires a new paradigm for an economic recovery that is rooted both in climate and economic justice as well as river stewardship. Since December 2020, hundreds of groups and individuals from more than 80 countries have joined the Rivers4Recovery call for a better way forward for rivers and natural places. This paradigm will protect our rivers as critical lifelines — supporting fisheries, biodiversity, water supply, food production, Indigenous peoples and diverse populations around the world — rather than damming and polluting them.
The promise of the Klamath dam removals is one of restoration — a move that finally recognizes the immense value of free-flowing rivers and the key role they play in nourishing both the world's biodiversity and hundreds of millions of people. Healthy rivers — connected to watershed forests, floodplains, wetlands and deltas — are key partners in building resilience in the face of an accelerating climate crisis. But if we allow the hydropower industry to succeed in its cynical grab for stimulus funds, we'll only perpetuate the 20th century's legacy of suffering and environmental degradation.
We must put our money where our values are. Twenty years ago, the WCD pointed the way forward to a model of development that takes humans, wildlife and the environment into account, and in 2020, we saw that vision flower along the Klamath River. It's time to bring that promise of healing and restoration to more of the world's rivers.

The latest warning of the Earth's mounting extinction crisis is coming from its lakes and rivers.
A new report from a coalition of 16 conservation groups warns that almost a third of freshwater fish species face extinction because of human activity.
"Nowhere is the world's nature crisis more acute than in our rivers, lakes and wetlands, and the clearest indicator of the damage we are doing is the rapid decline in freshwater fish populations. They are the aquatic version of the canary in the coal mine, and we must heed the warning," Stuart Orr, WWF global freshwater lead, said in a statement Tuesday announcing the report.
WWF is one of the many organizations behind the report, along with the Alliance for Freshwater Life, Conservation International and The Nature Conservancy, to name a few. Together, the groups emphasized the incredible diversity of the world's freshwater fish and their importance for human wellbeing.
There are a total of 18,075 freshwater fish species in the world, accounting for 51 percent of all fish species and 25 percent of all vertebrates. They are an important food source for 200 million people and provide work for 60 million. But their numbers are in decline. The IUCN Red List of Threatened Species has declared 80 to be extinct, 16 of those in 2020 alone. The numbers of migratory freshwater fish such as salmon have declined 76 percent since 1970, while mega-fish such as beluga sturgeon have fallen by 94 percent in the same time period. In fact, freshwater biodiversity is plummeting at twice the rate of biodiversity in the oceans and forests.
Despite this, freshwater fish get much less attention than their saltwater counterparts, the report authors say. Titled "The World's Forgotten Fishes," it argues that policy makers rarely consider river wildlife when making decisions.
The main threats to freshwater fish include building dams, syphoning river water for irrigation, releasing wastewater and draining wetlands. Other factors include overfishing, introducing invasive species and the climate crisis.
"As we look to adapt to climate change and we start to think about all the discussions that governments are going to have on biodiversity, it's really a time for us to shine a light back on freshwater," Orr told NBC News.
To protect these forgotten fishes, the report authors outlined a six-point plan:
1. Let rivers flow more naturally;
2. Improve water quality in freshwater ecosystems;
3. Protect and restore critical habitats;
4. End overfishing and unsustainable sand mining in rivers and lakes;
5. Prevent and control invasions by non-native species; and
6. Protect free-flowing rivers and remove obsolete dams.
They also called on world leaders to include freshwater ecosystems in an ambitious biodiversity agreement at the upcoming UN Convention on Biological Diversity conference in Kunming, China.
But the solution will require more than just government action.
"It's now more urgent than ever that we find the collective political will and effective collaboration with private sector, governments, NGOs and communities, to implement nature-based solutions that protect freshwater species, while also ensuring human needs are met," Carmen Revenga of The Nature Conservancy told BBC News.
