I am someone who does believe the human species is far to overpopulated in areas of the world, we can see proof of that in third world countries where the starvation is coupled with to many mouths to feed, no contraception, and probably men praying to their angry sky god for their not to be another mouth to feed, just to have five more a pop.
Where theres to many people and not enough resources, you then have conflicts created, and people leaving in droves from such regions, coupled with other countries taking said resources from them, escalating the problem.
We are to overpopulated. When there are over populations of animal species in a region that effects the natural wildlife, like toads eating frogs or crickets eating crops, we as a species cull those creatures by what we think as giving balance back, and yet, when our own species gets culled, its a genocide, a tragedy, something that rocks the world.
We're a kind of self absorbed species thats dickish to all others. We might have exceptions like conservation, but overall, the greater majority is more concerned about having their froffy cappuccino then the cows locked in place unable to move while being milked.
Speaking of being milked, I have some delightful images involving guys in such situations.
