The Endangered Species Act has had broad partisan support since being instituted in 1973. It has been credited with saving the bald eagle and grizzly bears, and continues to protect some 1600 species. The UN has determined that some 1 million plant and animal species are endangered.

The Trump administration’s changes to the Endangered Species Act include allowing consideration for economic factors, will no longer offer the same protections to “threatened” species as it does “endangered,” and removes any uniform interpretation of what risks species face in the foreseeable future.

His administration has rolled back several other regulations, including for offshore rigs and coal pollution.
