How long do you think it would take for the environment to purify itself from the pollution of mankind?
Has anybody thought about a computer model for this?

about a hundred years for the obvious stuff,deforrestation harmfull gassesmharmfull agriculture,but some things will take millions of years although much would end up burried,out of harms way ,such as silicone and oil contamination
Many desserts will remain ,we have set an drying out process into motion that is hard to reverse,and only Human intervention ,at great expense with advanced technowledgy and much labout can reforrest desserts ,but it can be done

Then there would be a over population of things like deer and the other things man kills. they would eventually overpopulate certain areas and their eating habits would probably destroy certain habitats or cause the extintion of some species in the food chain of the environment. without humans, all the endangered species would not be cared for.. and die too.
Certain things would stop like smog, yet some of the trash would take thousands of years to decompose. Brush fires would still be caused but not put out. Lightning can cause these too. The Earth would be habitable to be taken over by the next evolution.

Human pollution would be replaced by other pollution.
An increase in numbers of cattle and swine could yield much more methane gas.
Since there would be no firefighters, forest fires would be larger and more common, releasing tons of CO2 into the air.
Still, some things would clear up almost immediately. The air would become cleaner even after just a single day without cars or factories.
Other things could take decades, such as garbage dumps, or even hundreds of years, like toxic waste dumps.
These problems will be cleared up much more quickly by high technology in 50 or 100 years with human help.

Pretty fast, except for the unnatural long lived isotopes we've created.

At least we'd be rid of Al Gore.
