No, I'm not truly convinced yet. It hasn't reached the level of Darwinism yet, really, and it's become a heavily political movement, which makes me (unfairly or not) even more skeptical. However, I haven't ruled it out, and it's not like I don't have respect for people who do believe that it's a problem. That being said, even if it is, I really don't see what we, as Americans, can do about it. Do we lower production while China and India continue to pollute at astronomical rates (and they will be even larger polluters in the coming years) based on something that has not been completely accepted in the scientific community and end up losing ground economically? I don't think so. Not yet, anyway.
