Yea i agree the world is very overpopulated and if we look most animals are extinct or are becoming extinct. I think us humans can handle more heat then most of these animals but soon enough the earth wont take it. Causing natural disasters leading to something massive that many of us wont be able to survive.
I go camping in the backwoods often for solitude and experience nature, wildlife and fresh air. I make it a point to tread lightly to preserve what exists now. I hope this respect has some impact on the future.
