The Trump administration has announced rule changes that alter how it will enforce the 1973 Endangered Species Act, which protects threatened and endangered species and their habitats. Among these changes, officials can now consider potential costs in deciding whether to list a species. The new policies will make it easier to delist species, and are likely to shrink areas set aside as critical habitat to help species recover.
These five articles from The Conversation's archives describe public perceptions of the Endangered Species Act and the challenges of saving species on the edge.
Americans Support Protecting Endangered Species
Critics of the Endangered Species Act say the law is too bureaucratic and costly to private interests, and that states should have a bigger role. But when Ohio State University's Jeremy Bruskotter and Ramiro Berardo and Michigan Technological University's John Vucetich reviewed 20 years of data on public views of the law, they found that over that time, roughly 80 percent of Americans consistently supported it.
Notably, while liberals strongly favored protecting endangered species, nearly 75 percent of conservatives did so as well. In a 2015 survey, more than 70 percent of hunters, farmers and ranchers supported the Endangered Species Act.
Why, then, are critics of the law so determined to weaken it? The authors point to research showing that "policy outcomes in America are heavily influenced by 'economic elites' and business interests who … have greater clout with, and access to, policymakers" than average voters.
States Aren’t Equipped to Take Over
The Trump administration is proposing to downlist the American burying beetle (Nicrophorus americanus) from endangered to threatened. Once abundant throughout the Northeast, the beetle is now found in just five states.
Some regulators and members of Congress have pushed to delegate responsibility for listing and protecting endangered species to states. But University of California, Irvine legal scholars Alejandro Camacho and Michael Robinson-Dorn found that state statutes were much weaker than the Endangered Species Act. And states would have to massively increase spending to maintain the levels of protection that exist now.
"States have substantial authority to manage flora and fauna in their boundaries," the authors wrote. "But species often cross state borders, or exist on federal lands. And many states either are uninterested in species protection or prefer to rely on the federal government to serve that role."
The authors found room for better consultation between federal agencies and states, but argue that rather than dismantling the Endangered Species Act, Congress should provide enough funding to achieve the law's goals.
Regulators Need to Set Priorities

As it stands, conservation agencies don't have enough funding or time to write recovery plans for more than 1,600 listed species listed. Choosing which ones to protect raises complicated tradeoffs between science and values. And without recovery plans, species are unlikely to rebound.
Arizona State University biodiversity scholars Leah Gerber and Timothy Male sought to develop an effective system for guiding these choices. They designed a decision tool called Recovery Explorer that uses an algorithm to identify the most cost-effective choices for recovery, based on factors such as geography, biology and the likelihood that funding will actually lead to recovery.
"Scientists and policymakers now have an opportunity to develop a more workable strategy to improve the Endangered Species Act," they write. "And for those species that are deemed worthy of protection, the next steps will be to promote their recovery and be willing to pay for it."
Species Can Rebound with Help

The American bald eagle is often cited as an example of an endangered species that has made a successful comeback. But its cousin, the osprey (Pandion haliaetus) is an even more spectacular case.
Ospreys were abundant across North America up through World War II, catching fish in rivers, lakes and harbors. But like bald eagles, they were devastated starting in the 1950s by DDT and other insecticides, which poisoned the birds and prevented them from successfully hatching eggs. By the mid-1960s populations had plummeted.
Ornithologist Alan Poole believes that Ospreys' disastrous decline helped make the case for banning DDT and other insecticides that were lethal to wildlife. The other key, he writes, was widespread construction of poles to support osprey nests:
"Within just a few miles of where I live along the Massachusetts coast, over 200 Ospreys now nest each year, lured in by abundant nest poles we've built on wide-open marshes. Fewer than 20 Ospreys were found here in the 1960s."
While ospreys were never formally listed under the Endangered Species Act, Poole believes they were near the brink of extinction 50 years ago. He calls their recovery "a reward for all who value wild animals, and a reminder of how nature can rebound if we address the key threats."
Some Species Are Running out of Time
Thousands of right whales once swam in the North Atlantic, but today there are only about 411 left. This critically endangered species is threatened by collisions with ships and entanglement in fishing gear, which can cause traumatic injuries that slowly kill or cripple the animals.
Michael Moore and Hannah Myers of the Woods Hole Oceanographic Institution say it's critical to develop alternative gear for lobster and crab fishermen that will eliminate ropes from the water column, where whales are likely to swim into them. Options in development include pop-up buoys that fishermen summon with an acoustic signal and sensors that acoustically identify traps on the ocean floor.
While some fishermen call these technologies unaffordable, others are helping to test them. "Just as no fisherman wants to catch a whale, researchers and conservationists don't want to put fishermen out of business," Moore and Myers assert. "In our view, ropeless technologies offer a genuine opportunity for whales and the fishing industry to co-exist if they can be made functional, affordable and safe to use."

The Science Behind Frozen Wind Turbines – and How to Keep Them Spinning Through the Winter
By Hui Hu
Winter is supposed to be the best season for wind power – the winds are stronger, and since air density increases as the temperature drops, more force is pushing on the blades. But winter also comes with a problem: freezing weather.

While traditional investment in the ocean technology sector has been tentative, growth in Israeli maritime innovations has been exponential in the last few years, and environmental concern has come to the forefront.

<p>The UN hopes that new investments in ocean science and technology will help turn the tide for the oceans. As such, this year kicked off the <a href="https://www.oceandecade.org/" target="_blank" rel="noopener noreferrer">United Nations Decade of Ocean Science for Sustainable Development (2021-2030)</a> to galvanize massive support for the blue economy.</p><p>According to the World Bank, the blue economy is the "sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem," <a href="https://www.sciencedirect.com/science/article/pii/S0160412019338255#b0245" target="_blank" rel="noopener noreferrer">Science Direct</a> reported. It represents this new sector for investments and innovations that work in tandem with the oceans rather than in exploitation of them.</p><p>As recently as Aug. 2020, <a href="https://www.reutersevents.com/sustainability/esg-investors-slow-make-waves-25tn-ocean-economy" target="_blank" rel="noopener noreferrer">Reuters</a> noted that ESG Investors, those looking to invest in opportunities that have a positive impact in environmental, social and governance (ESG) issues, have been interested in "blue finance" but slow to invest.</p><p>"It is a hugely under-invested economic opportunity that is crucial to the way we have to address living on one planet," Simon Dent, director of blue investments at Mirova Natural Capital, told Reuters.</p><p>Even with slow investment, the blue economy is still expected to expand at twice the rate of the mainstream economy by 2030, Reuters reported. It already contributes $2.5tn a year in economic output, the report noted.</p><p>Current, upward <a href="https://www.ecowatch.com/-innovation-blue-economy-2646147405.html" target="_self">shifts in blue economy investments are being driven by innovation</a>, a trend the UN hopes will continue globally for the benefit of all oceans and people.</p><p>In Israel, this push has successfully translated into investment in and innovation of global ports, shipping, logistics and offshore sectors. The "Startup Nation," as Israel is often called, has seen its maritime tech ecosystem grow "significantly" in recent years and expects that growth to "accelerate dramatically," <a href="https://itrade.gov.il/belgium-english/how-israel-is-becoming-a-port-of-call-for-maritime-innovation/" target="_blank" rel="noopener noreferrer">iTrade</a> reported.</p><p>Driving this wave of momentum has been rising Israeli venture capital hub <a href="https://www.thedockinnovation.com/" target="_blank" rel="noopener noreferrer">theDOCK</a>. Founded by Israeli Navy veterans in 2017, theDOCK works with early-stage companies in the maritime space to bring their solutions to market. The hub's pioneering efforts ignited Israel's maritime technology sector, and now, with their new fund, theDOCK is motivating these high-tech solutions to also address ESG criteria.</p><p>"While ESG has always been on theDOCK's agenda, this theme has become even more of a priority," Nir Gartzman, theDOCK's managing partner, told EcoWatch. "80 percent of the startups in our portfolio (for theDOCK's Navigator II fund) will have a primary or secondary contribution to environmental, social and governance (ESG) criteria."</p><p>In a company presentation, theDOCK called contribution to the ESG agenda a "hot discussion topic" for traditional players in the space and their boards, many of whom are looking to adopt new technologies with a positive impact on the planet. The focus is on reducing carbon emissions and protecting the environment, the presentation outlines. As such, theDOCK also explicitly screens candidate investments by ESG criteria as well.</p><p>Within the maritime space, environmental innovations could include measures like increased fuel and energy efficiency, better monitoring of potential pollution sources, improved waste and air emissions management and processing of marine debris/trash into reusable materials, theDOCK's presentation noted.</p>theDOCK team includes (left to right) Michal Hendel-Sufa, Head of Alliances, Noa Schuman, CMO, Nir Gartzman, Co-Founder & Managing Partner, and Hannan Carmeli, Co-Founder & Managing Partner.

<p>theDOCK's own portfolio includes companies like Orca AI, which uses an intelligent collision avoidance system to reduce the probability of oil or fuel spills, AiDock, which eliminates the use of paper by automating the customs clearance process, and DockTech, which uses depth "crowdsourcing" data to map riverbeds in real-time and optimize cargo loading, thereby reducing trips and fuel usage while also avoiding groundings.</p><p>"Oceans are a big opportunity primarily because they are just that – big!" theDOCK's Chief Marketing Officer Noa Schuman summarized. "As such, the magnitude of their criticality to the global ecosystem, the magnitude of pollution risk and the steps needed to overcome those challenges – are all huge."</p><p>There is hope that this wave of interest and investment in environmentally-positive maritime technologies will accelerate the blue economy and ESG investing even further, in Israel and beyond.</p>- 14 Countries Commit to Ocean Sustainability Initiative - EcoWatch ›
