John,

This year marks the 50th anniversary of the Endangered Species Act. No law has done more to save wildlife from extinction. But the law is only as strong as the rules used to implement it on the ground.

Unfortunately Trump gutted these rules on his way out the door. Now President Biden has the chance to not only undo Trump’s actions but go further and strengthen protections for our most vulnerable plants and animals. Sadly his administration has left most of the bad Trump changes in place.

Since its inception the Act has protected millions of acres of forests, mountains, rivers, deserts, beaches, oceans and other habitat — as well as the fragile and fascinating network of life we know as biodiversity. It has also become an inspiration for other countries in their pursuit of wildlife protection.

It’s the reason bald eagles still soar across our skies, grizzlies and wolves roam the Rockies, blue whales migrate along the West Coast, and American alligators stomp through the Southeast.

But its work is far from over: We still face the loss of 1 million species in the coming decades. So we need to make sure the Act is as strong as possible.

The U.S. Fish and Wildlife Service and NOAA Fisheries have proposed to restore some of the protections that were slashed under Trump. But instead of leading the effort to address the extinction crisis, they’re proposing to keep in place the majority of the harmful Trump policies that are pushing species like polar bears, northern spotted owls and gulf sturgeon toward extinction.

Tell Biden’s agencies you expect more of them. They must revoke the Trump rules in their entirety to ensure a strong Endangered Species Act for the next 50 years and beyond.
