Tell Congress to oppose the ESA Amendments Act!

For more than 50 years, the Endangered Species Act (ESA) has been one of the most effective environmental laws in U.S. history, preventing the extinction of the vast majority of species protected under it. From bald eagles to sea turtles, the ESA has given wildlife a fighting chance to recover—guided by science, not politics.

Now, that progress is at risk.

Congress is advancing the ESA Amendments Act of 2025, legislation that would significantly weaken the law’s core protections at a moment when biodiversity loss is accelerating nationwide. According to reporting by National Park Traveler, the bill threatens species already on the brink by narrowing habitat protections and making it harder to list new species before it’s too late. Conservation experts warn that these changes could push vulnerable wildlife closer to extinction rather than recovery.

Major advocacy and environmental organizations are sounding the alarm. Humane World reports that the bill would undermine the scientific standards that ensure wildlife decisions are based on evidence rather than political pressure. NRDC has documented how this legislation fits into a broader wave of attacks on the ESA that favor industrial development over ecosystems, public lands, and long-term environmental health.

The ESA is popular across party lines and has proven its value time and again. Weakening it would harm wildlife, damage ecosystems, and set a dangerous precedent for rolling back science-based environmental protections nationwide.

Your member of Congress needs to know that this bill (H.R. 1897) and any other legislation that weakens the Endangered Species Act is not acceptable. 

Take action today by writing a letter to your representative and asking them to oppose H.R. 1897, the ESA Amendments Act.

Thanks,
