Just wondering what the general consensus of opinion on this subject is. It seems to be a political taboo to even speak of it.

I think the world's ideal "sustainable" population is somewhere between 2 and 4 billion mark. At current levels and beyond we are destroying the environment, directly (and indirectly) causing other species to become extinct and affecting climate change. Not to mention the speed that we are consuming our irreplaceable deposits of fossil fuel.

Before anyone replies i would urge you to watch the following link. It may be the most important video you have ever watched:

Arithmetic, Population and energy - part 1 of 8

Unfortunately, due to religious, moral and economic reasons there are no easy answers to this problem.

Another interesting link regarding population:

Easter Island - A microcosm of earth?


The above happened hundreds of years ago but is still, in my opinion, very relevant to our current situation.

Thoughts?
