The difficult of predicting the future and the effects of global warming. It may happen and maybe not, but do you care enough to make the catastrophe happen and if not - do you want to pay with your life or your money? It is a preachy instruction movie but Al Gore is an engaging preacher that would have made a better president than some other that I have seen. Anyhow, the real bastards of pollution are businesses.
DVD. I used it today as an introductory vehicle for future lessons on climate change and global warming. I had never seen it before and always suspected that, as usual, the hype had to do with the subject and not the construction and i wasn't mistaken. I didn't know that on the way there were several deviations to the protagonist's magnificence - and the way it's done is debatable. Very much so. Just pedagogical.
