You have to remember, if there was a nuclear winter, the earth would have no life for thousands of years
Actually, according to David Suzuki, we're already in a nuclear winter. I'll have to find that article again, it was really interesting.
I think you're all pretty much right. Yes, the world constantly creates and destroys land. The problem, I think, lies in the fact that we as a species expect permanancy. We have built cities in beautiful places... directly in say, the hurricane belt. Or on the deltas of a major river. Look at New Orleans. The whole area used to change as sediments were washed in and out by the mississippi. Then we built walls around it to hold back the water. Now the region constantly loses STAGGERING amounts of land every year because there is no way to replenish it. Then Hurricane Katrina comes along. New Orleans was meant to be a pirate cove, not a major metropolis but we stubbornly hang on.
I think my point is that we fight nature directly head on most of the time. The things that Mother Earth does to actually fix the population tend to be more subtle, I think. Superbugs? Drug resistant strains? The diseases we've been fighting since day one are strong enough to overcome some of our best work. That, I think, is population control.
Oh, and I plan to have one baby myslef and adopt another.
