Dr. Albert Allen Bartlett is an emeritus Professor of Physics at the University of Colorado at Boulder, USA. He has lectured over 1,600 times on Arithmetic, Population, and Energy. He explains that sustainable growth is a contradiction, since modest annual percentage population increases will inevitably equate to huge exponential growth over sustained periods of time. He therefore regards human overpopulation as "The Greatest Challenge" facing humanity.

The above video is an excerpt from his lecture Arithmetic, Population and Energy. You can find the full video here:
