What do you think can we do about GLOBAL WARMING?

Sometimes I think man has left it too late to do anything, we have taken and taken from this earth without giving back, without appreciating what we had, I think in the name of greed I think. The world is a big complex thing, mother nature gave to us and we took unfortunately we didn't wake up to what we have done and still people don't seem to care all that much, I think we have to stop doing a lot of things and I don't think big companies are going to let that happen...it is scary.
