Eh, I think we are all doomed!

The world is already way too overpopulated and it is only going to exponentially grow. There is nothing that can be done, its too late. The only thing that could stop human usage of the world's resources is a disease, or bacteria that has the capability to deplete the human population like the black plague of the middle ages. Education will not come soon enough and people have no desire to change their ways of life. Even if there is a major disease that could drop the population numbers, human intelligence would most likely develop a way to overcome it. Sadly, we are too smart for our own good. Basically there is nothing we can do, just go eat a lollipop and watch the brown and gray sun set over huge, nasty piles of pollution!
