Will the earth be able to sustain all of us? If so, for how long? These are questions that few of us think about. Our concerns are about the economy, global warming, world conflict, immigration, local violence and crime. But maybe all these issues are triggered by the one and most important real problem that we are facing today: world overpopulation. Regardless of how bad this issue is, its like the elephant in the room, no one seems to care, no one talks about it, its like we are in denial. But is there a real and reachable solution for this problem? Yes, there is.
