EPA Underestimated Number of Polluted Florida Streams, Lakes and Rivers
Floridians may end up paying a few more pennies a day in the coming years to upgrade outdated sewer systems that are contaminating public water supplies, the National Academy of Sciences (NAS) said in a report on March 6.
The report says that even more Florida lakes, streams, rivers and springs are polluted than previously thought, and that earlier estimates by the U.S. Environmental Protection Agency (EPA) underestimated the scope of the problem.
In predicting costs, the EPA estimated that preventing sewage, manure and fertilizer contamination in Florida waters would cost Floridians less than a dollar a month—or about three cents a day.
Today’s National Academy of Sciences report says that, since more Florida waters are polluted than the EPA estimated, it could cost more to prevent pollution. The report doesn’t specify how much.
“Even if you doubled the EPA’s cost estimate—which this report doesn’t do—you’re still talking about spending about a nickel a day for clean water. I think it’s a fair price to pay to stop toxic green slime from breaking out on our waterways,” said Earthjustice attorney David Guest.
The contaminants in sewage, manure, and fertilizer spur green, slimy toxic algae outbreaks on Florida waterways that can pollute drinking water supplies, kill livestock and pets, cause rashes, breathing problems, stomach disorders, and worse. Pictures are available by clicking here and here.
The pollution can be prevented by upgrading aging sewer systems, using smarter fertilizer application techniques and implementing modern manure management on agricultural operations.
“The polluters have been exaggerating and trying to scare the public so that they won’t have to clean up their mess,” Guest said. “Face it—It’s a lot cheaper for them to keep using our public waters as their private sewers—and that’s what’s been happening for years.”
The EPA decided 14 years ago that limits on the pollutants that feed slime outbreaks were necessary. Three years ago, the EPA and the Florida Department of Environmental Protection agreed that specific pollution limits must be quickly implemented—but efforts to establish limits were met by a massive campaign by polluting industries to stop or delay the new rules.
“No private party has the right to contaminate the public’s water, and this is why standards must be set to protect everyone’s health and safety,” said Florida Wildlife Federation President Manley Fuller. “People are tired of the roadblocks these polluters keep throwing up. We want our waters cleaned up.”
More than 17,000 people have written to the White House during the past month, supporting the EPA limits. The White House letters came in response to a grassroots call to action from several environmental groups.
After years of seeing toxic algae on Florida tourist beaches like Sanibel Island and at fishing destinations like the St. Johns River, Earthjustice filed a Clean Water Act federal lawsuit in 2008 in the Northern District of Florida on behalf of the Florida Wildlife Federation, the Conservancy of Southwest Florida, the Environmental Confederation of Southwest Florida, St. John’s Riverkeeper, and the Sierra Club. In 2009, the EPA set numeric limits for the phosphorus and nitrogen that comes from sewage, fertilizer and manure in the water.
Earthjustice is now challenging the ineffective standards to control this pollution proposed by the Florida DEP. The DEP’s proposed rules only require studies when an algae outbreak takes place. No corrective action can be required until the studies are completed, a process that takes five to ten years. An administrative hearing challenging the DEP’s rules concluded March 5.

As we enter what's hopefully the home stretch of the COVID-19 pandemic, it's time to take stock of how it affected every aspect of our world, to consider what happened, what could be done different to avoid those problems in the future, and what's next.

However, it's not all stories of dolphins frolicking in suddenly quiet rivers. Environmental planning meetings, funding schemes for protected areas, and monitoring of fisheries and endangered species populations were all disrupted, giving us good reasons to fear that the story is far more complicated, and far less happy, than many of us have been led to believe.</p>

A new study is shedding light on just how much ice could be lost around Antarctica if the international community fails to urgently rein in planet-heating emissions, bolstering arguments for bolder climate policies.
The study, published Thursday in the journal Geophysical Research Letters, found that over a third of the area of all Antarctic ice shelves — including 67% of area on the Antarctic Peninsula — could be at risk of collapsing if global temperatures soar to 4°C above pre-industrial levels.

This week, Secretary Haaland chose a visit to Bears Ears National Monument as her first trip as Interior Secretary. She is spending three days in Bluff, Utah, a small town just outside the monument, listening to representatives of the five tribes who first proposed its designation to President Obama in 2015. This is the same town where former Secretary Sally Jewell spent several hours at a public hearing in July 2016 before recommending the monument's designation to President Obama.

The tropical water at the equator is renowned for having the richest diversity of marine life on Earth, with vibrant coral reefs and large aggregations of tunas, sea turtles, manta rays and whale sharks. The number of marine species naturally tapers off as you head towards the poles.
The Bell Curve is Warping Dangerously<img class="rm-lazyloadable-image rm-shortcode" lazy-loadable="true" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNjAzODUwNi9vcmlnaW4ucG5nIiwiZXhwaXJlc19hdCI6MTY3NzE1OTU4N30.qQL3P1IvA7Cwj_UbsrAL6MVZvafXGZc7hlAFieLPvso/img.png?width=980" id="9bbfd" width="1580" height="872" data-rm-shortcode-id="16ca57badee20ad55037706875f813f4" data-rm-shortcode-name="rebelmouse-image" />
If you look at each line in this chart, you can see a slight dip in total species richness between 1955 and 1974. This deepens substantially in the following decades. Anthony Richardson, Author provided<p>This global pattern — where the number of species starts lower at the poles and peaks at the equator — results in a bell-shaped gradient of species richness. We looked at distribution records for nearly 50,000 marine species collected since 1955 and found a growing dip over time in this bell shape.</p>
This Has Happened Before<p>We shouldn't be surprised global biodiversity has responded so rapidly to global warming. This has happened before, and with dramatic consequences.</p><p><strong>252 million years ago…</strong></p><p>At the end of the Permian geological period about 252 million years ago, global temperatures warmed by 10℃ over 30,000-60,000 years as a result of greenhouse gas emissions from volcano eruptions in Siberia.</p><p><a href="https://www.pnas.org/content/117/30/17578" target="_blank" rel="noopener noreferrer">A 2020 study</a> of the fossils from that time shows the pronounced peak in biodiversity at the equator flattened and spread. During this mammoth rearranging of global biodiversity, 90% of all marine species were killed.</p><p><strong>125,000 years ago…</strong></p><p><a href="https://www.pnas.org/content/109/52/21378" target="_blank" rel="noopener noreferrer">A 2012 study showed</a> that more recently, during the rapid warming around 125,000 years ago, there was a similar swift movement of reef corals away from the tropics, as documented in the fossil record. The result was a pattern similar to the one we describe, although there was no associated mass extinction.</p><p>Authors of the study suggested their results might foreshadow the effects of our current global warming, ominously warning there could be mass extinctions in the near future as species move into the subtropics, where they might struggle to compete and adapt.</p><p><strong>Today…</strong></p><p><a href="https://www.pnas.org/content/117/23/12891" target="_blank" rel="noopener noreferrer">During the last ice age</a>, which ended around 15,000 years ago, the richness of forams (a type of hard-shelled, single-celled plankton) peaked at the equator and has been dropping there ever since. This is significant as plankton is a keystone species in the foodweb.</p><p>Our study shows that decline has accelerated in recent decades due to human-driven climate change.</p>
The Profound Implications<p>Losing species in tropical ecosystems means ecological resilience to environmental changes is reduced, potentially compromising ecosystem persistence.</p><p>In subtropical ecosystems, species richness is increasing. This means there'll be species invaders, novel predator-prey interactions, and new competitive relationships. For example, <a href="https://www.abc.net.au/news/2019-09-13/sydney-growing-own-coral-reef-with-help-from-tropical-fish/11466192" target="_blank">tropical fish</a> moving into Sydney Harbour compete with temperate species for food and habitat.</p><p>This could result in ecosystem collapse — as was seen at the boundary between the Permian and Triassic periods — in which species go extinct and ecosystem services (such as food supplies) are permanently altered.</p><p>The changes we describe will also have profound implications for human livelihoods. For example, many tropical island nations depend on the revenue from tuna fishing fleets through the selling of licenses in their territorial waters. Highly mobile tuna species are likely to move rapidly toward the subtropics, potentially beyond sovereign waters of island nations.</p><p><span></span>Similarly, many reef species important for artisanal fishers — and highly mobile megafauna such as whale sharks, manta rays and sea turtles that support tourism — are also likely to move toward the subtropics.</p><p>The movement of commercial and artisanal fish and marine megafauna could compromise the ability of tropical nations to meet the <a href="https://sdgs.un.org/goals" target="_blank">Sustainable Development Goals</a> concerning zero hunger and marine life.</p>
Is There Anything We Can Do?<p>One pathway is laid out in the Paris Climate Accords and involves aggressively reducing our emissions. Other opportunities are also emerging that could help safeguard biodiversity and hopefully minimise the worst impacts of it shifting away from the equator.</p><p>Currently 2.7% of the ocean is conserved in <a href="https://mpatlas.org/" target="_blank">fully or highly protected reserves</a>. This is well short of the 10% target by 2020 under the UN Convention on Biological Diversity.</p><p>But <a href="https://www.gov.uk/government/topical-events/global-ocean-alliance-30by30-initiative/about#global-ocean-alliance-members" target="_blank">a group of 41 nations</a> is pushing to set a new target of protecting 30% of the ocean by 2030.</p><p>This "30 by 30" target could ban seafloor mining and remove fishing in reserves that can destroy habitats and release as much carbon dioxide as <a href="https://www.nature.com/articles/s41586-021-03371-z" target="_blank">global aviation</a>. These measures would remove pressures on biodiversity and promote ecological resilience.</p><p>Designing climate-smart reserves could further protect biodiversity from future changes. For example, reserves for marine life could be placed in refugia where the climate will be stable over the foreseeable future.</p><p>We now have evidence that climate change is impacting the best-known and strongest global pattern in ecology. We should not delay actions to try to mitigate this.</p><p><em><a href="https://theconversation.com/profiles/anthony-richardson-100303" target="_blank">Anthony Richardson</a>: Professor, The University of Queensland. <a href="https://theconversation.com/profiles/chhaya-chaudhary-1223419" target="_blank" rel="noopener noreferrer">Chhaya Chaudhary</a>: University of Auckland, <a href="https://theconversation.com/profiles/david-schoeman-111544" target="_blank" rel="noopener noreferrer">David Schoeman</a>: Professor of Global-Change Ecology, University of the Sunshine Coast, <a href="https://theconversation.com/profiles/mark-john-costello-1223418" target="_blank" rel="noopener noreferrer">Mark John Costello</a>: Professor, University of Auckland</em></p><p><em>Disclosure statement: Anthony Richardson receives funding from the Australian Research Council.</em></p><p><em>Chhaya Chaudhary works for Goethe University, Frankfurt am Main, Germany.
