Greg Craven's Argument

Greg Craven is the creator of "The most terrifying video You'll ever see". In this video, Greg Craven talks about the Global Climate Change (GCC). In this video he explains the four possible outcomes that can happen in the near future, and the future of the world depends on how we act. First of, Craven explains how if we take action but there is no GCC, we will loose money and we will enter global depression, he then moves on to saying that what if we don't take action and there is no GCC, we will all be happy as we have lost no money and there is no GCC. He then states, what if the GCC is true, and we take action, there will still be a cost factor, however, we will remain happy. Finally he moves on to the final outcome, saying, what if we don't take action and GCC is true. The world will end up in a catastrophe, which involve social, economical, health problems. Now in group "A", we have cost and global depression, as well as, Cost but happiness to us all. In group "B", we have Happiness, however we also have a global catastrophe. Craven argues that group "A" is the right choice, even though we will loose money in both the outcomes, however, the risk of not acting (Group "B") far out weighs the risk of acting (Group "A"). He explains how the best choice will be "A" because that option has the chance of eliminating a global catastrophe. I agree with Craven's argument, why would we chose choice "B" which has a possibility of a catastrophe when we can chose "A" in which both outcomes are not so bad. Yes, we may loose money, but isn't it worth a shot to try and save the world?
