Climate change plus human pressure caused large mammal extinctions in late Pleistocene

>"Humans tend to impact the bigger animals, with the smaller animals as collateral damage," he said. "Climate change is just the opposite - it affects the little guy first and then, through them, the big guys. Today, we see humans taking out the bigger animals and climate change affecting the smaller animals, so we can expect to see some pretty dramatic changes in the ecosystem."

One major problem today is that, because of human encroachment, there are no refuges for animals that might want to relocate because of climate change.

"One thing we can do, as conservationists, is to create and connect natural areas" to allow animals to move around, he added. "Because species can no longer do this by themselves, maybe the solution is to do it for them."
