A legal shift could leave endangered species unprotected
The Trump Administration Defangs the Endangered Species Act
The proposed interpretation could make accidental deaths and habitat destruction harder to prosecute, weakening incentives to prevent biodiversity loss.
- 1The Endangered Species Act evolved from regulating hunting to protecting habitats essential to species survival.
- 2Court rulings established that destroying critical habitat can constitute illegal harm, even without directly killing an animal.
- 3The administration’s intentional-harm standard could exclude deaths from ships, logging and construction while facing legal challenges.

Einhorn explains how the proposed intentional-harm standard could leave whales struck by vessels and bats killed during tree felling outside enforcement.
The brief
Catrin Einhorn traces the Endangered Species Act from the environmental crises of the 1960s to a broad system protecting endangered animals and their habitats.
The law’s pivotal question is what counts as harm: courts have held that destroying essential habitat can violate the act, even when no animal is directly targeted.
A proposed interpretation drawing on Justice Scalia’s dissent would require intentional harm, potentially excluding deaths caused by ships, logging, construction and other activity.
That change could remove incentives to prevent collateral damage, especially for species with only a few dozen individuals, while weakening the ecological protections built around them.
Wildlife advocates and states are challenging the policy, turning a dispute over statutory language into a larger test of how the country responds to biodiversity loss.
