The only thing I dislike about Gore is his hypocritical personal energy gluttony. I voted for him against Bush and think we'd be all be better off is he had won.
Whether global warming is caused by human activities or not, we need to start changing the way we do things, if merely because we will be running out of fossil fuels in the next century. If we don't plan for that civilization as we know it will utterly collapse.
This all proves that it's a good idea and profitable to invest in infant energy industries. They are our future.
