Sorry to be so cheery, but the idea that the moment we are gone, everything will go back to pristine paradise is unprovable and lets us all collectively off the hook a bit too easily.

Thats interesting but it has absolutely nothing to do with wilderness.
<<SNIP>>
There isn't a lot of wilderness left in the world.
We are lucky here in Alaska. The vast majority of Alaska is still wilderness.

It may someday become wilderness, but I think it is highly unlikely we would recognize it as an ecological community today.
By the end of the 15th century, between 40 million and 80 million people are thought to have been living in the Americas. Many of them burned trees to make room for crops, leaving behind charcoal deposits that have been found in the soils of Mexico, Nicaragua and other countries.
About 500 years ago, this charcoal accumulation plummeted as the people themselves disappeared. Smallpox, diphtheria and other diseases from Europe ultimately wiped out as much as 90 percent of the indigenous population.
Trees returned, reforesting an area at least the size of California, Nevle estimated. This new growth could have soaked up between 2 billion and 17 billion tons of carbon dioxide from the air.
Ice cores from Antarctica contain air bubbles that show a drop in carbon dioxide around this time. These bubbles suggest that levels of the greenhouse gas decreased by 6 to 10 parts per million between 1525 and the early 1600s.
“There’s nothing else happening in the rest of the world at this time, in terms of human land use, that could explain this rapid carbon uptake,” says Jed Kaplan, an earth systems scientist at the Federal Polytechnic School of Lausanne in Switzerland.

I know I was. Nature seems to have its own secrets when it comes to restoring balance and equilibrium - in a single organism's body or in the biosphere itself. Reports like these give me hope as well as food for thought.
