The World Without Us

There’s a lot of discussion these days about whether or not humankind is putting excessive pressure on our earth’s finite resources. Population growth, new technologies for extracting fossil fuels, depletion of forest lands, loss of clean fresh water sources, garbage in the oceans, over fishing, the list goes on and on.

I was reading an interesting commentary on what would happen to our world if humankind was suddenly to disappear, how quickly it would rebound, become healthy again. Such a scenario, human extinction that is, is not all that unthinkable in view of international tensions these days.

Such thinking made the book, The World Without us, by Alan Weisman, compelling reading. Mr. Weisman suggests that, in his believable future world, infrastructures would begin to fail, the New York subway tunnels would flood almost immediately and within a few hundred years our most solidly built brick, mortar and concrete structures would crumble. Native vegetation would push up through asphalt roadways hastening nature’s reclamation of the earth. Coral reefs and sea life would rebound as the resilient oceans healed themselves.

Even 500 years later the earth, it seems to me, would be a much more attractive place to be; except, of course, I wouldn’t be there; unless I could somehow live in the future. But, I guess that’s a whole other issue.
