This Ocean Farmer Grows Food That Cleans up Pollution
By Marlene Cimons
Catherine Puckett needs to be close to the ocean. "I just can't be away from it," she said. "It means everything to me." She has to see it and smell it and hear the bells that ring from buoys offshore when a heavy sea rolls in from the east. When she is waist-deep in water, ankle-deep in mud, salt marsh on one side and water on the other, there's only one way she can describe it. "It's magical," she said. She even wades in during the coldest days of winter, often breaking through ice to get there. "I think to myself: 'why doesn't everybody do this?'" she said.
Puckett, 36, known locally as "Oyster Wench," a single mother with two young children, lives on Block Island, about a dozen miles off the Rhode Island coast. She represents a new generation of ocean farmers, one whose singular connection to the water is coupled with a passion for the environment. She grows shellfish and kelp on her farm, located in the waters of the Great Salt Pond, using sustainable fishing methods that both preserve the ocean's ecosystems and fight climate change.
"What we are trying to do is grow food from the ocean that doesn't hurt the environment or the climate and, in fact, is working toward restoring both," she said.

She is one of a growing number of ocean farmers engaged in 3D farming, cultivating her crops vertically in straight up-and-down water columns, using no fertilizers, freshwater or feed. Puckett's clams are buried and covered with nets to protect them from predators, while her oysters grow in bags. Her kelp develops on lines.
The operation helps cut down on pollution in numerous ways. The shellfish help filter pollutants from the water. They also offer a source of protein to diners, who might otherwise eat beef, which is made from cows who burp and fart methane, a potent heat-trapping gas. For those who can't give up their beef, ocean farming can help. Research shows that when cows eat a little seaweed, they produce less methane.
Seaweed also soaks up carbon and nitrogen, two pollutants lingering in the water. Carbon released by cars, trucks, factories and power plants is entering the ocean, turning waters more acidic. Nitrogen fertilizer used on farms is making its way into rivers and then to the ocean, creating dead zones. Seaweed cleans up both. If ocean farmers devoted a little less than 5 percent of U.S. waters to growing seaweed, they could clean up an estimated 135 million tons of carbon and 10 million tons of nitrogen, according to a report from the World Bank.

Puckett sells most of what she produces to a Maine food processor, and the remainder to land farmers who use it to fertilize their vegetables. "The kelp is sequestering carbon and nitrogen, so by selling it to the farmers as fertilizer, we are closing the loop," she said. "We are making the circle complete." She also keeps some for herself. She uses it in salads, as a substitute for spinach, and as a pizza topping. She also dries it, then bakes chips. "Those never make it out of the kitchen," she said.
Puckett developed her operation with the help of GreenWave, a nonprofit helping aspiring growers get into vertical farming. Bren Smith, a former commercial fisherman, founded the organization after seeing the global fishing industry was decimating wild fish. He developed his vertical farming system off the shores of the Long Island Sound in Connecticut. It's now being used by growers in New York, southern New England, California, Alaska and the Pacific Northwest.
"We have requests to start farms in every coastal state in North America and from 20 countries," said Smith, author of a new book, Eat Like a Fish. "People come from all walks of life. They are shell fishers, like Catherine, who are looking to diversify, former fishermen who want to transition, land-based farmers who want to leave the land, and indigenous people who want to revive their traditions and be on the forefront of climate farming."
He believes his model could ease overfishing, which threatens the extinction of many fish species. "We have to reimagine the seafood dinner plate and move wild fish to the edges, and put shellfish and seaweed to the center," Smith said. "Because what we grow has zero inputs, our food will be the most affordable food on the planet."

Puckett shares this vision. After spending childhood summers on Block Island, she later decided to stay and fish. She started by working for the Block Island Shellfish Farm, then bought it five years ago. She's the only woman on the island running an ocean farm, and her bright teal and pink boat — still unnamed — is a standout.
"My kids wanted me to paint it rainbow and sparkle, but I said how about pink?" she said, laughing. "I wanted to make a statement that it was a 'girl' boat. There are a couple of guys here who help me with the kelp harvest who tease me — that they have to go out on a girl boat — but they are OK with that. Actually, the men here have known me for a long time, and have seen me go through my growing pains, and have helped me so much."
Puckett started with quahog clams, and then added scallops and oysters. She had long wanted to grow seaweed, but didn't know where to start. Another oyster farmer told her about GreenWave's Farmer-in-Training program, which taught her how to use the 3D model, then gave her free kelp seed for her first harvest. She now farms a one-acre shellfish site, and — in deeper waters — a two-acre kelp site, both leased from the state. Her kelp "grew like crazy," she said. "It was mind-blowing."
The Block Island wind farm, the first commercial offshore wind farm in the U.S.
Puckett is happy that her work is curbing pollution, and she is proud that Block Island is the site of America's first offshore wind farm, which began operating in 2016 and has boosted tourism to the island, according to a recent study. Puckett eyes the turbines as future anchors to grow her seaweed. Smith thinks it's a great idea. "Why just harvest wind, when we can do food and fertilizer in the same space?" he said.
Smith wants to replicate Puckett's success elsewhere. "Imagine the impact if we scaled this model globally. The possibilities are limitless," he said. He envisions 50 small scale farms, each with a seafood hub and hatchery on shore, and a ring of entrepreneurs to develop markets for the products.
"We want to have 100,000 Catherine Pucketts worldwide," he said. "Amazingly, the people coming to this industry are not grizzled fishermen like me — we have plenty of those — the majority are women. This means women could be the architects of the blue economy. That is a very exciting prospect."

Coronavirus Shines Light on Zoos as Danger Zones for Deadly Disease Transmission Between Humans and Animals
By Marilyn Kroplick
The term "zoonotic disease" wasn't a hot topic of conversation before the novel coronavirus started spreading across the globe and upending lives. Now, people are discovering how devastating viruses that transfer from animals to humans can be. But the threat can go both ways — animals can also get sick from humans. There is no better time to reconsider the repercussions of keeping animals captive at zoos, for the sake of everyone's health.

Bernice Dapaah calls bamboo "a miracle plant," because it grows so fast and absorbs carbon. But it can also work wonders for children's education and women's employment – as she's discovered.
These are the world's most bicycle-friendly cities. Statista<p>"The reason we use bamboo to manufacture bicycles is because it's found abundantly in Ghana and this is not a material we're going to import," says Dapaah, one of the World Economic Forum's Young Global Leaders.</p><p>"It's a new innovation. There were no existing bamboo bike builders in our country, so we were the first people trying to see how best we could utilize the abundant bamboo in Ghana."</p>
<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="a335b5dffdd806bd6bb4debea90c2045"><iframe lazy-loadable="true" src="https://www.youtube.com/embed/dxsb9c4HMn0?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span>
Supporting Students<p>Besides encouraging Ghanaians to swap vehicles for affordable bikes, Ghana Bamboo Bikes Initiative is helping students save time on walking to school so they have more time to learn.</p><p>Each time they sell a bike, they donate a bike to a schoolchild in a rural community, who might otherwise have to walk for hours to get to school.</p><p>Dapaah knows how transformative a shorter journey to school can be to academic performance. She grew up living with her <a href="https://www.youtube.com/watch?v=sb3joGYmx9A&feature=emb_logo" target="_blank">grandpa, a forester in a rural part of the country</a>.</p><p>"We had to walk three and a half hours every day before I could go to school. He later bought me a bike, so I finished senior high and wanted to go to university."</p><p>The experience inspired her to launch Ghana Bamboo Bikes Initiative with two other students at college.</p><p>"When we started this initiative, I looked back and said, when I was young, I had to walk miles before I could get to school, and sometimes if I was late, I was punished.</p><p>"Why don't we donate bikes for students to encourage them to study and so they can have enough time to be on books."</p><p>To date, they have sold more than 3,000 road, mountain and children's bikes – and Dapaah says they plan to donate <a href="https://www.entrepreneur.com/video/350343" target="_blank">10,000 bikes to schoolchildren over five years</a>.</p>
Empowering Women<p>The enterprise is also providing local jobs. It teaches young people to build bikes, particularly women and those in rural communities, where jobs can be scarce. More than 50% of people they have trained are women.</p><p>Dapaah says they want to boost the number of people they employ to 250 over the next five years and they are looking to partner with NGOs to build a childcare facility so mothers can continue to work.</p>
Reducing Emissions<p>By promoting a cycling culture in Ghana, Dapaah says they're also committed to reducing emissions in the transport sector and contributing to the UN's Sustainable Development Goals.</p><p>"I love the idea of reusing bamboo to promote sustainable cycling. People want to go green, low-carbon, lean-energy efficient," she says.</p>

Melting and crumbling glaciers are largely responsible for rising sea levels, so learning more about how glaciers shrink is vital to those who hope to save coastal cities and preserve wildlife.
Groans, Creaks, Icebergs’ Calving Splashes<p>Oskar Glowacki already knew that melting glacial ice sounds like frying bacon. As ice bubbles burst, anyone nearby can hear crackling and popping, said Glowacki, a postdoctoral scholar at the Scripps Institution of Oceanography. Using hydrophones, he and other scientists now can make more nuanced measurements of how a changing climate sounds underwater, from the groans, creaks and splashes of a calving iceberg to the changes in whale songs as the ocean warms.</p><p>Glowacki recently used a pair of hydrophones to study the underwater world of glaciers, publishing his findings in <a href="https://www.the-cryosphere.net/14/1025/2020/" target="_blank">The Cryosphere</a>. He and co-author Grant B. Deane measured glacier retreat by <a href="https://yaleclimateconnections.org/2020/07/melting-glaciers-sound-like-frying-bacon/" target="_blank">recording the sounds of ice</a> – from small chunks to enormous slabs – falling off the glacier and splashing into the water.</p><p>During the summer of 2016, Glowacki's team placed two hydrophones near Hansbreen Glacier in Hornsund Fjord, Svalbard. For a month and a half, they recorded sounds, also using three time-lapse cameras to collect images – including the "drop height" (how far the ice fell into the water) – so they could compare photos to the recordings. The team created a formula to represent the relationship between the size of a piece of ice falling from a glacier and the sound it makes underwater, also accounting for the pieces of ice falling from varying heights. (Hear an example of the sound an iceberg makes while calving <a href="https://soundcloud.com/user-248456662/iceberg-calving-hansbreen-glacier" target="_blank">here</a>.)</p>
Unlocking Information About Antarctic Ice Shelf<p>Other researchers also are using hydrophones to learn more about crumbling glaciers. Bob Dziak, research oceanographer with the NOAA/Pacific Marine Environmental Laboratory <a href="https://www.pmel.noaa.gov/acoustics" target="_blank">acoustics research group</a>, captured a massive calving event of the Nansen Ice Shelf in Antarctica with a hydrophone. He published the results with colleagues in <a href="https://www.frontiersin.org/articles/10.3389/feart.2019.00183/full" target="_blank">Frontiers in Earth Science</a></p><p>On April 7, 2016, satellite images showed a massive calving event had occurred on the ice shelf. The paper described it as the "first large scale calving event in >30 years."</p><p>However, once Dziak and colleagues delved into the data from three hydrophones deployed 60 kilometers east of the ice shelf, they uncovered a series of "icequakes" from January to early March 2016. He and other researchers believe that much of the ice actually broke free in mid-January to February, but it remained in the same location until an April storm – which their paper described as the "largest low-pressure storm recorded in the previous seven months" – broke the ice free.</p><p>"We suspected that the icebergs broke apart but remained in place – kind of pinned in place – until a major storm with high winds passed through the area and, finally, it was that last push that pushed the icebergs out to sea," Dziak says.</p><p>He and his co-authors wrote that "fortuitous timing and proximity of the hydrophone deployment presented a rare opportunity to study cryogenic signals and ocean ambient sounds of a large-scale ice shelf calving and iceberg formation event."</p>
Listening to Songs of Humpback Whales<p><a href="https://www.mbari.org/" target="_blank">Monterey Bay Aquarium Research Institute</a> studies the ocean, including its acoustics. One of the institute's projects involves examining the soundscape of California's Monterey Bay, including sounds from animals, humans, weather, and geologic processes like earthquakes. The researchers once even recorded an under-sea landslide. They also focus on recording and analyzing the <a href="http://www.mbari.org/humpback-song/" target="_blank">songs of humpback whales</a>. Male humpback whales' songs can be over 15 minutes in length, and they can be repeated for long periods of time – even hours. Listening to these songs and analyzing them can provide unique insights into the lives of these complex animals.</p><p>"Any time we want to study marine mammals, sound gives us a window into their lives because they use sound for all of their essential life activities, really," says institute biological oceanographer John Ryan. "Communication, foraging, reproduction, navigation – depending on the species, of course."</p><p>Previously, scientists had thought singing occurred only during courtship and mating, but now they think whales may also use song while migrating and hunting. They know song has a crucial role in the whales' lives.</p><p>"There's a whole other dimension to humpback whale song," Ryan says. "It is a mode of cultural transmission in this species. They learn songs from each other. They share songs as a population, and when populations mix and mingle, they learn new ideas, they explore with their song, improvise, and it's a real essential part of their culture."</p>

A number of conservationists claim cats are a zombie apocalypse for biodiversity that need to be removed from the outdoors by "any means necessary" – coded language for shooting, trapping and poisoning. Various media outlets have portrayed cats as murderous superpredators. Australia has even declared an official "war" against cats.
Faulty Scientific Reasoning<p>In our <a href="https://doi.org/10.1111/cobi.13527" target="_blank">most recent publication</a> in the journal Conservation Biology, we examine an error of reasoning that props up the moral panic over cats.</p><p>Scientists do not simply collect data and analyze the results. They also establish a logical argument to explain what they observe. Thus, the reasoning behind a factual claim is equally important to the observations used to make that claim. And it is this reasoning about cats where claims about their threat to global biodiversity founder. In our analysis, we found it happens because many scientists take specific, local studies and overgeneralize those findings to the world at large.</p><p>Even when specific studies are good overall, projecting the combined "results" onto the world at large can cause unscientific overgeneralizations, particularly when <a href="https://doi.org/10.1016/j.tree.2015.01.003" target="_blank">ecological context is ignored</a>. It is akin to pulling a quote out of context and then assuming you understand its meaning.</p>
Ways Forward<p>So how might citizens and scientists chart a way forward to a more nuanced understanding of cat ecology and conservation?</p><p>First, those examining this issue on all sides can acknowledge that both the well-being of cats and the survival of threatened species are legitimate concerns.</p><p>Second, cats, like any other predator, affect their ecological communities. Whether that impact is good or bad is a complex value judgment, not a scientific fact.</p><p>Third, there is a need for a more rigorous approach to the study of cats. Such an approach must be mindful of the importance of ecological context and avoid the pitfalls of faulty reasoning. It also means resisting <a href="https://doi.org/10.1111/cobi.13126" target="_blank">the siren call of a silver (lethal) bullet</a>.</p>
