tboy said:The only thing you're missing is the word eventually and possibly. We've impacted the earth to such an extent that the damage we've done (and are doing) is probably at the point now that it cannot recover naturally. As Bliss pointed out: how many species have become extinct? How many species are full of mercury? If they're damaged at a genetic level then there is no recovery without our intervention.
Same as nuclear reactors. If all the reactors in the world went critical, and radiation leaked all over the planet, no species would survive......(except maybe for roaches, they survive nuclear fallout)
After a million years I'm guessing there would be no evidence of humans or nuclear radiation and there would be life on earth.
Gotta think long term. :biggrin:
