Anybody who ever studied ninth grade biology knows that a colony of bacteria will die in its own poisons, despite an abundance of food. We have a choice here. We can take care of the earth as if our lives depended on it. (and they do!) Or we can do nothing. In that case the earth will take care of herself. She will balance. Eventually, enough of the human race will die off (or kill each other off) to a point where our polution is no longer a problem. So You tell me what you think should be done.
