Yes, it is defeatist, in the sense that I realize the insignificance of humanity. Do you honestly think you can change the world for the better? Do you think a million people could, or even a billion? A change could be made, but in the grand scope of things, it would be negligible. There are facts here that trump everything that environmentalism and conservation could possibly accomplish: our species will become extinct, and our planet will recover relatively quickly from any damage we have incurred.
edit: @Hubster - I don't believe I said that humans are not affecting the environment. It's just that we are not affecting it significantly. Everyone here is thinking in terms of human time, not geologic time. I feel it is more than likely that in 1 million years the only evidence of our existence will be in fossils, and the air and water will most likely be nice and clean.
Yes, humanity is insignificant, but the damage trhat we've created isn't. By the time we're extinct, the effect of a (future) damaged environment isn't going to be akin to 65 million years ago, it will be much worse, because we will sicken this planet to it's core with our weapons by the time we vanish off it's surface.
Yes, perhaps it will heal itself. but I don't see it being something on a rapid timescale at all. Regardless, it doesn't give us the right to blunder around chopping things to pieces, scouring whatever we like and destroying the balance of life around us, which we NEED to survive. I just don't see it as a logical justification.
Keep another thing in mind: by the time above occurs, China and India will have become fully industrialised, an doubt no Russia will rise once again too by such a time (I speak of decades to come). How will the planet handle that extra load, with a possible seven fully industrialised nations when it's already buckling under the current load?
Edit:
I am thinking in geological timeframes, but because of said industrialisation, the earth would not have experienced such a rate of deep poisoning before. Thin scars heal, yes. But "deep wounds", "infections" etc... on a planetary scale, these will take a very LONG time to heal. Again, it still doesn't give us the right to mindlessly ruin our surroundings. It's not good for us as a species.
