The U.S. Department of the Interior is effecting significant changes that weaken how the Endangered Species Act is implemented, a move critics fear will allow for more oil and gas drilling on land that is currently habitat-protected, and will limit how much regulators consider the impacts of the climate crisis. The changes affect how the U.S. Fish and Wildlife Service and National Oceanic and Atmospheric Administration consider whether species qualify for protections, as well as how the agencies determine what habitats deserve special protections. It could make it more difficult to factor in the impact of climate change on species.
