I'm for living a good life and for doing the best I can. I look around and see things for what they are. Man, as a whole, is a very selfish species. People will march over the top of homeless people sleeping on the sidewalk while they carry signs and chant about freedom and rights.
We are on a downward spiral and will create our own demise. Whether it be nuclear war or over population, or a 100 other destructive scenarios. Planting windmills and capturing some sun certainly won't same us. It would take a lot more than that.
