"An Inconvenient Truth" was a very interesting movie. Having a strong belief that the environment is important and that we should preserve what we have, I found his points very valid. At the same time, he was very one sided like any politician can be, and lacked the sense in several parts of the documentary to understand the big picture. Regardless of Al Gore and his views, global warming is the issue that we all have to evaluate...
A constant temperature increase is already causing problems, but is bound to cause many more. The fact that we continue to pollute and destroy the ozone layer amazes me. I realize that it would be a huge process to shut things down and revamp our world industries, but where does our future lie. The world is indefinitely doomed if we continue to pollute.
What happens once the polar ice caps have completely melted away? This will be a very long time, but after that the oceans will raise in temperature and the same problem that happened back in the Permian Period of this earth will reoccur. The ocean's temperature had little differential between the poles and their was a mass extinction of aquatic life. 96% to be exact! This would cause chaos and throw off hundreds of life cycles, in addition to industries. We have to keep our eyes open today to make a future possible for tomorrow.
