how long do we have?

As we continue to pollute our environment how long will it be until we (humans as a species) kill ourselves off? How much will it take to make this earth so toxic to human life that we either die, or live in miserable conditions? Can we go on for 1000 years, 100 years 10 years? What are we leaving future generations? These are questions most people don't want to answer. One thing is for sure, I am damn sick and tired of hearing the characteristic bs from hedonistic pigs that we have nothing to worry about. They use the same science that is telling us we need to make changes to justify their greed by showing "proof" that there really is no problem with pollution. Give me a freakin' break. GOD! what is wrong with these jerks. If there is any history to be read years from now these jackasses will be viewed with contempt for sure. Just hope that some future civilization finds a way to bring these idiots back to life and punish them.
