“For millions of years, our distant ancestors led a precarious existence as scavengers, hunters, and gatherers, and there were fewer than 10 million human beings on Earth at any one time. But over the last two centuries, the world’s population has skyrocketed. By October of 1999, some crowded cities had more than 10 million inhabitants each, and six billion people shared space on the planet. Trace the dramatic growth and spread of human populations on our global map, and see where on Earth as many as three billion more people may live by 2050.

Very interesting interactive. The population explosion in Africa is so severe that I can easily envision the time will come when only humans occupy the continent. The wildlife will have to be destroyed to try to feed the poulation.
Very true, mostly due to technology advances in medicine, food production, economic stability in the western world.
It is the same technology that can feed them if only corrupt governments would get out of the way.
