Yup. the time will come where we can no longer sustain ourselves, then we will die off, at least to a much smaller group. Only then the earth might have a chance.
My vote is for asteroid to hit and end it all for all of us. Or a volcano, a much slower way to go, but the end result is the same. That would be the simplest solutions.
I think the time is sooner than we'd like to beleive.
