The Trump administration on Thursday announced plans to roll back the Endangered Species Act, ordering federal agencies to consider economic impacts before listing animals as protected under the law. The newly proposed guidelines by the Interior Department would allow corporations involved in mining, drilling or other forms of extraction to proceed with projects that would otherwise be prohibited. In response, the Natural Resources Defense Council tweeted, “This is unacceptable. The ESA is a wildly successful piece of legislation that has prevented 99% of the species it protects from going extinct.”
