I would be interested in your reply to the post by Alexander4450? Do you agree with him?
My answer to your question , is it is way too late. Selfishness and greed is unfortunately part of human nature. The planet will fight back with reaction, and will win, and it will eventually recover differently with or without human beings. If any survive, they will be few and THEN they might have a chance to wake up to the mistakes for a while, until selfishness and greed takes over again.
Steve, does your outlook agree with Alexander's, or disagree.
