A documentary made involving Al Gore and supported by many celebrities that is based on the THEORY that Global Warming is the effect that pollution has on the earth causing abnormal weather and eventually the end of our healthy environment.
It is not based on science but on a random pick in theory and has never been proven to be true, but non the less billions of dollars are spent everyday trying to "prevent" the made up fear called "global warming".
What many of us are forgetting is the truth about pollution which is that it causes ashma nad is the leading cause of new deadly deseases, and hightens the chance of cancer in an individual by over 90%.
The weather changes that we find so "abnormal" are actually the natural progression of the aging earth as the universe expands and all of the galaxies become further away from each other, and the earth moves away from the sun.
"an inconvenient truth" is bull crap at it's best, the best peice of non-scientifical diagrams the world has ever seen.
