I recommend everyone see The Inconvenient Truth. It is an inspiring and thought provoking movie educating us about global warming. It made me proud of Al Gore for standing up and speaking the truth.
It also refreshed/renewed my faith in the process of life. Here is a man who lost (sort of) the presidency and went on to make a contribution to the world that seems even more poignant.
