Ultimately, none of it matters. In a billion years the sun will burn out and our entire planet will be destroyed with nothing remaining but a few chunks of rubble floating around the galaxy. All life on earth is ultimately meaningless and without a point. Human beings are vain and misguided at best, evil and cruel at the worst. Life is indeed nasty, brutish, and short. Bring on the fossil fuels, nuclear waste, war and economic oppression. You only live once, it applies as much to the planet as to an individual. Lets use up this earth for all we can, as quickly as possible and make an end of it.
