Question/Topic For Class

A question that I've thought a lot about, recently, is why isn't anybody doing anything? There's so much research and so many people are devoted to figuring this whole equation out, but for what? Action needs to be taken and it needs to happen now. When a large enough number of people come together to make this change a reality, only then could even the slightest changes begin. Do we, as a people, really even want to change?
