Sign On: Oppose Rule that Weakens the Endangered Species Act

We need your voice to help defend one of our most important wildlife protection laws.

The Endangered Species Act (ESA), established 50 years ago, has been one of our nation's most powerful tools for preventing extinction. But a proposed change to the ESA threatens to weaken habitat protections for listed species.


Currently, the ESA prevents the direct killing of federally listed species. It also prevents "harm," which is any action that would negatively affect the species, including damaging or destroying habitat. The proposed change would remove the definition of harm, a change that is intended to undermine habitat protections for endangered species.


The Xerces Society invites you to join our letter opposing the proposal to remove the definition of "harm" from the ESA, which would ignore decades of legal precedent and put endangered species at risk of rapid extinction.

The Xerces Society is a donor-supported nonprofit organization that protects our world through the conservation of invertebrates and their habitats. Learn about Xerces.
