Don't worry, I lead a very happy and fulfilled life, and just want to convince others to if nothing else change the excessively wasteful way of life we lead (I had to convince myself at one point also). I don't want to worry about where we are headed as a species, but I think if we aren't at least conscious of our affect on the world around us, one day we will look up and see that we are in trouble. That's all. I know the only view you have of me is the original post, which makes me seem like an apocolyptic doomsayer, running around telling people that we're all gonna die, but trust me I'm not like that at all.
