More: In what would be a seismic shift, the Trump administration is quietly moving to strip a core protection of the Endangered Species Act, according to an internal memo obtained by The New York Times.

Under a new interpretation of the law's language outlined in the memo, the accidental killing or injury of an animal would no longer be considered illegal; only actions specifically intending to target an animal would.

The change would be transformative because, in the United States, the killing of endangered animals almost always happens incidentally, in the course of economic activity. Until now, industries and individuals could be held accountable for those foreseeable deaths and, as a result, they have been incentivized to avoid them.
