Not to put too fine a point on it, but human procreation seems to be the problem moreso than individual carbon footprint.
I think the one ecological concept often overlooked is the idea that there really aren't any wasted resources; everything is being used by something. Each additional human usurps resources that could be growing more butterflies or elephants. The trick of course, is figuring out some kind of balance that makes sense to each of us on a personal level. The desire to minimize our own impacts is often over-ridden by the biological desire to pass on genetic information even though we all know how un-important our own genes are in a population sense. But sustainability will simply never occur on a finite planet with an ever increasing human population no matter how much some of us attempt to reduce our individual footprints. Just my 2 cents, discounted for inflation. -Tim
