Actually, that is the problem, It's called carrying capacity. The problem is that most people are afraid to admit it. If the earths population were half what it currently is we wouldn't be having this discussion about burning fossil fuels, or depleting our fisheries, or that we've destroyed 99% of the native prairies in the USA.
I digress. If you think things are crowded now, think about this, current estimates project that the world's population will double again in the next 54-72 years. Chew on this, if we cut the worlds per capita carbon output in half, we will be in the same situation 60 years from now that we are today, if nothing else changes.:sad:
