I think we'll go because of a polluted environment. So I say it will take thousands of years to restore balance to the earth.

We will all be gone before all the trees get cut down, thats what makes alot of our oxygen, they take in carbon dioxide ( which is deadly to us)and expell oxygen

Not that long. Plant a Christmas tree next December and see how big it is in 10 years.

I've been watching the History Channel series about life on earth after people. It's fascinating. Judging by the Mayan remains, a few 100 years.

Uh-oh... do you know something I don't? Wait- are you a diabolical mastermind just trying to figure out a time-table for nature to restore itself after you've wiped humanity from the globe?! Eegads! (take answer with large grain of salt. Or more than a grain, if so desired)

Double the time it actually took in the beginning.Nature should first get rid of all the dirties we have left and then regenerate its resources.So double the time.

if the planet is not a nuclear wasteland, despite the effects of pollution, after 100-200 years the earth will look much like it did before the 'superior' animal species dicked it up

What you forget is, that it took us ~8-9000 years to cut down a small portion of the forests, in that period the rate of our destruction was somewhat on par with how fast the forests could regrow, and since then it's been an uneven balance.. But, I think it'll take a good while. In some areas whole forests doesn't just appear from one day to the other, besides, several species has become extinct, so restoring the forests with a varity in species similar to how it was before the global industrialisation can take several thousand, if not milions of years, in my oppinion

I cut down half of my forest about 5 years ago. It will be ready to cut again in another 10 years when the middle growth trees (who now have sunlight) will grow stronger. By then, this year's saplings will be middle growth, and I will harvest the large trees and the cycle will begin again. I guess I just exposed myself as an evil tree killer, didn't I? (If you please, no complaints from anyone with oak furniture or cabinets... It may have come from my woods, and it would be quite hypocritical to DR my answer and have any wood in your house.) The real concern with reforestation, is whether or not a newgrowth forest can be seeded. One of our largest forest/agricultural problems coming up is the declining bee population. Once the bees die off, it's pretty much a "done deal" No pollination by bees = very little new growth. Long story short... With bees, wind and good climate, I can't imagine it not being completely overgrown in 50 years. Without bees --- Mars.

We haven't ''cut down half the world's forest''... yet.
