I was just thinking a bit about this. Since the impact theory is under a lot of criticism (especially in regards to being responsible for extinctions specifically), there are some newer alternative theories that pin the megafauna extinctions to potential human activity. Afterall, this sudden cooling period probably took a massive toll on the growing food supply and probably left huge mammals as the best source of calories for humans. It would then make sense that in the absence of decent growing conditions, humans would systematically hunt down anything they could to feed themselves. So, if this is how it "went down", we can conclude that we are not in quite a good place in comparison. First, most of our large supply of wild animals are already suffering. Secondly, there are a lot more of us (those animals wont last too long with 8 billion humans hunting them all).
