I somewhat agree with Harpgirl but she's too much of a butterfly for my tastes. I'll stick with cheeseburgers.

Massive increases in population in places like Africa were caused by drops in the death rate rather than by increases in the birth rate. It looks like we are all part of a global problem. David Suziki's book, It's a Matter of Survival has some disturbing information on trend lines and thing like the fact that there are more of us alive today than have lived in rest of the history of (wo)mankind.

Yet few of us are volunteering to leave the planet. I don't know about you but I was just kidding when I said that I would kill myself.
