I understand there are more resources in some areas than others in the world. The world is not over populated. Most people happen to live in urban areas so it appears to be over crowded. If hoever the population was more dispersed, over crowding would not be a problem. It's not over populated or else we would not have space to build or travel by road.
Nothing is in the hand of man.
Really over populated. I have never understod why Arabs fell the need to get 10-12 children. Especially the poor families. No, but I believe most Muslim countries are over populated, while most western countries are underpopulated. The problem is the fact that most of the resources are distributed to the west, where they are not needed nearly as much.
