World population

World population growth
The BMJ records an interesting description of how the world population has grown out of control.
The first modern human was about in about 160000 BC.
In AD 1 the world population was 250 million
1776 1 billion
1945 2.3 billion
2006 6.5 billion
The human population has quadrupled in less than 100 years.
The annual increase in population of the world is 79 million
This has profound implications for the future of the world
So we worry abut whether or not we eat too much of this and that. Or the millions of starving and quietly and surely we are driving the human race into extinction by over populating the globe
