We will not destroy the world, once some kind of ballance is once again obtained it will start to recover, at the rate we are going there will most likely be very few humans around to see it happen though.

I don't think we will destroy the earth, asteroids can't destroy the planet they can however erase entire ecosystems and press the reset button on our planet. I think what were currently doing the world over is equal to that; Earth will always be here, human beings might not. I'd hate for an intelligent life form to make itself extinct when its entirely avoidable. Simply put we have too many people not enough resources anymore, oil and coal is why we can support the population we have. Well actually that's a lie, we can't support the population we have right now. What oil and coal has done is enabled us to cheat, without those resources our planet could sustain around 3.5-4Billion people that would be homeostasis. That's the point we need to get back to, our oceans can't sustain us anymore and our agriculture is inadequate. We would literally have to turn the entire continent of Africa into a farm to match the demand for food we will need for our growing population and do so by 2040. Our population today is about 7 Billion people, and what's truly frightening is if you extend the graphs out for our fisheries, well they just plain out will not exist by 2050.
When presented with this information and the studies to back it up, people attack the information and the studies and don't want to believe it. Its not comforting to actually be able to look out and see an end point for sustainability. It often causes responses like, "So what's your solution kill 3.5Billion people?" Well no, the solution is to prevent any further population growth and to lower our population via a 1 child policy globally. That was the purpose behind China's 1 child policy to reduce population they just failed terribly to do it. Being as that will never happen, and unless every nation on the planet is willing to jump on the wagon of sustainable development my solution is much more caliginous. We do nothing at all, we keep doing as we have been doing because even if we were to miraculously get every person in Canada and the United States on board with conservation of the oceans; there's 1.344 Billion Chinese, and 1.241 Billion Indian's who would completely nullify our cause.
