That's the spirit that the U.S. was built on. Unbridled greed and self interest, #### everyone and anything that gets in the way of it. That's why we have the environmental problems we've got now. Unchecked, things are going to get real ugly all over the place, and it won't be localized. You think the U.S. has an immigration problem now? Just wait until sea levels rise, desertification really kicks in in currently high population/poorly economically developed areas, and all those folks are looking for a new place to stay alive.
This planet has conducted a number of experiments in various lifeforms. Might be our run is just about up. The difference between us and the species that died off before is it'll be all self inflicted damage on our part. Smart enough to figure out the means to destroy the environment we require to live, but not smart enough to keep from doing it. I hope the insect people learn from us in a couple million years.
