Just for the sake of conversation......................
I don't completely buy this for 2 main reasons.
1. There are groups of scientists that suggest that "Global Warming" is actually a natural cycle of the earth. The idea is simply that our short livespans are too small to really be able to recognize the pattern of change as a natural event, not the result of human activity. Supposedly, according to this crowd, if we could look back in time and have good temperature data for 10000 years, we would see this pattern take place off and on, warmer and colder.
2. Corals are VERY adaptive. So we are losing some species of corals (and if that REALLY is our fault, then indeed shame on us). HOWEVER, where these die out, new species will survive which can t take the warmer heat. NO, I am not a believer in Evolution. But I do believe that the created world is very flexible. And if anything out there can better demonstrate flexibility in nature, that would be the coral reef. Look at how you can take a coral and put it in horrendously different conditions. And it's response? It will change it's shape of growth or density of polyps or something.
Way freaking cool.
Now, we should probably as a whole planet slap ourselves and start taking better control of our environment. But then again, how many of us sacrifice convenience to carpool to work? (etc, etc, I know I don't)
