hmm actually from what i have read over population is more of a problem.
the world has little left that is still belonging to the world. most we humans took and destroyed.
there is a good point that agent smith makes in the matrix
he said humans are like viruses they move from area to area and destroy every thing along the way, sucking all of the resources and manipulating them for the worse.
thats we are doing.
even obama started globally funding abortions because too many countries are too overcrowded, because the girls in africa can't afford or maintain a healthy life. its not just in the us its everywhere.
in china you have to kill your first born baby. this world is on its way to overcrowding.
this world is already beginning to be "overpopulated"
