Daniel knows how to save the world.

There are many things we can do to save the world but I think one of the important things we have realize in the world is how much waste that we create and how much of it is unnecessary. Once we truly realize that we can conserve so much more than we are right now only then will our life on this planet last longer. Even then it's hard to tell that we can even save the planet after wasting so much and all the overpopulation. Another thing we have to do as a world is to spend more money on learning more about other planets, like Ryan said, and making them livable. Another thing that we need to spend money on research is how to create some sort of artificial food, like Soylent Green(/sarcasm). The funding for such programs could come from all the money that we are spending on wars and research on nuclear weapons etc. I don't think that it is possible for us to be able to start creating more resources than we are using because the world will never come together in peace to allow every single country to drop its military and start focusing on what is important. It is a sad thing to realize that human extinction isn't far from now when you think about it in terms of how long the planet has been around and how long the planet WILL be around.
