WATCH | Outrage as Trump administration weakens endangered species law
US President Donald Trump's administration on Monday finalised rollbacks to key provisions of the Endangered Species Act, a law supported by a large majority of Americans and credited with saving the grey wolf, bald eagle and grizzly bear.
The move was met with anger by environmental groups and Democratic politicians, including presidential candidate Joe Biden, while two states announced they would take legal action.
Amendments include removing a rule that automatically conveys the same protections to threatened species and endangered species, and allowing information on economic impact to be gathered when making determinations on how wildlife is listed.
In a statement characterising the changes as "improvements", Interior Secretary David Bernhardt said: "The best way to uphold the Endangered Species Act is to do everything we can to ensure it remains effective in achieving its ultimate goal - recovery of our rarest species.
"An effectively administered Act ensures more resources can go where they will do the most good: on-the-ground conservation," added the former oil and gas lobbyist.
Biden, the leading contender for the Democratic party's nomination in next year's presidential election, hit back, saying the amendments could push some species toward oblivion.
"For decades, the Endangered Species Act has protected our most vulnerable wildlife from extinction. Now, President Trump wants to throw it all away," he tweeted.
"At a time when climate change is pushing our planet to the brink, we should strengthen protections - not weaken them."
He was joined in his criticism by Democratic Senator Dianne Feinstein of California, whose state is home to 296 protected plant and animal species.
Conservation groups also reacted with dismay, vowing legal challenges against what the non-profit Sierra Club dubbed the "Trump Extinction plan".
Kristen Boyles, an attorney for Earthjustice, said: "Prior to today, a newly-listed threatened species would immediately have protections in place, there was sort of a default rule."
But "a species could be listed right now and it would have no further protections than it did before it was listed under the act" until a species-specific review takes place, she added, and even then it was not clear how robust those protections would be.
Other changes include modifications allowing companies to build roads, pipelines, mines, and other industrial projects in an area designated as a "critical habitat" for a species - paving the way for its gradual destruction so long as each individual step is sufficiently modest.
"So it allows this death by a thousand cuts," said Boyles.
Federal agencies may also begin gathering information on the economic impact of listing animals as threatened, despite the fact that the statute as passed by Congress explicitly states that science alone should determine if species should be protected.
Species like the grey wolf saw their population decimated in the early 20th century, but staged a remarkable comeback thanks to the law - which was signed by Republican president Richard Nixon in 1973 - and are now legally hunted in the Northern Rockies.
Similarly, there are today some 10 000 nesting pairs of bald eagles, the national symbol of the US, from a low of 417 in 1963.
A 2018 paper published in the journal Conservation Letters found that about four in five Americans support the act, while one in 10 oppose it, and support for the law has remained stable over the past two decades.
"The great majority of Americans value our natural heritage and find inspiration in it. This administration seeks to trash what so many value, what excites our children and generations to come," said Duke University conservation ecology professor Stuart Pimm.
Since taking office, the Trump administration has targeted more than 80 environmental and health regulations in the name of easing regulatory burdens on business.
Environmentalists have fought back with lawsuits, and some rollbacks have later been reinstated.
The attorneys general of California and Massachusetts announced their intention to sue the administration over the changes to the act, and other Democratic-led states could follow.
