Extinction....Hmm
One thing we can boldly say is controlled by the predators and the rate at which we prey on other organisms. Humans are the major causes of extinction in most cases. For example:
I don't have an idea of how many chimpanzees we have here in Nigeria, but the one that was seen yesterday in the Eastern part of the country was attacked and roasted... That's a minus one. I really don't think we have too much to start killing them, a few more killings and we might not have any Chimpanzees here anymore...

Nice Topic but I've been wondering if there's a possiblity of human beings being extinct with our rate of reproduction and death...
