These animals survived multiple climate changes before that. Nope, it was humans.
We're the reason the North American continent has _no_ large predators except bears.

- cyberax 1y agoSure. A couple of species will go extinct. But somehow ALL the megafauna in Australia, Asia, and North America went extinct at approximately the same time humans arrived.
