I believe in climate change. As it has always happened for hundreds of millions of years. It's all part of the evaluation of this planet . where I'm sitting right now at one time was a tropical forest, another time it was a desert, again another time it was an ocean, on more than one time there was more than a mile of ice. There's probably been millions of plants animals and insects that have come and gone that we'll never know about. And if curtain species of deer birds bears and fish can't evolve with the changing environment, then they'll disappear too. Including the human animal. I really enjoyed this thread and the posts. it shows that there are a lot of well read intelligent people on HBC and I hope in the future there more threads like it. Oh and what I wrote above, just one persons opinion. Nothing more, and nothing less.
