The president of the United States approved of a change in language to the Endangered Species Act of 1973. The revised definition allows for the aggressive exploitation of habitats of endangered species provided that the entire species isn’t threatened by that exploitation. The same president made it harder for citizens to petition for putting a species on the endangered list. That president was Barack Obama.
And there’s more. As a 2016 press release by the Center for Biological Diversity put it: “Over the past five years, the Obama administration has enacted several other administrative changes to the Endangered Species Act that collectively weaken its effectiveness.”
