My point is simple. I believe we humans are in real trouble. I believe that before nature dies from us screwing around she will get rid of us. If you are religious, well maybe God is sick of us. He said we have dominion over the earth not the right to destroy or even wound it. As to what can we do about it, I have no idea except be aware of it and acknowledge our part in it. In my lifetime the Earth has changed I don't need scientist to tell me this. I personally do not want to see any species vanish, but I must admit sometimes we humans are very worrisome.
