8 Trump Administration Removes Habitat Destruction from Endangered Species Act Protections¶

The Trump administration finalized a rule on July 10, 2026, that removes habitat destruction from the regulatory definition of "harm" under the Endangered Species Act. The change, effective September 14, 2026, allows farming, drilling, mining, logging, and development to proceed in endangered species habitats without violating the law, weakening decades of habitat protection policy and undermining U.S. conservation credibility internationally.

Trump administration rule removes habitat destruction from ESA "harm" definition, effective September 14, 2026
Habitat loss is a primary driver of extinction; the change separates habitat protection from species protection
Development and resource extraction in endangered species habitat no longer constitutes illegal "take" under the act
The policy reverses a legal interpretation upheld by the Supreme Court in 1995's Babbitt v. Sweet Home
Weakens federal consultation requirements for projects affecting listed species outside designated critical habitat areas

7 Bluefin tunas return to Yorkshire waters for first time since 1960s¶

Two giant bluefin tunas were caught off Yorkshire for the first time in over 60 years, marking a significant marine conservation success. The recovery is attributed to International Commission for the Conservation of Atlantic Tunas (ICCAT) management that allowed populations to rebuild and recolonize historical ranges.

First bluefin tuna catch in North Sea since 1960s
Two fish caught off Yorkshire near Whitby in week of August 19
Species nearly fished to extinction in Mediterranean during 1970s–1980s
Recovery driven by ICCAT stock protection and management
Bluefin return coincides with increases in minke whales and bottlenose dolphins in North Sea over past decade
