ecologist

Bear ecologist Chris Morgan says that, while he wouldn’t use the word “lazy” to describe black bears, he would absolutely call them efficient.

The English recognized this destructive pattern, but it took until 1968 for ecologist Garrett Hardin to give it a name and framework in his influential essay in Science magazine entitled “The Tragedy of the Commons.”

The heat can also cause what ecologists call "sub-lethal effects", where species essentially go into survival mode and don't reproduce.

And even if all living rhinos were dehorned, desperate poachers could still kill them for the remaining horn on their heads, said Lucy Chimes, a black rhino ecologist at the South African nonprofit Wildlife ACT.

"For a long time, most ecologists didn't treat urban areas as 'natural' environments, because humans lived in them. ... If we don't believe humans are part of the natural world, we're in trouble."
