The following two clips explore the mathematics of continual exponential growth and how it is linked to the doubling effect. Both point out the risks of these natural phenomena and the impact they have had and will have on society, resources and the environment.

He was President of the American Association of Physics Teachers in 1978 and in 1981 he received theirRobert A. Millikan Award for his outstanding scholarly contributions to physics education.
This video by gives an understanding exponential growth as a fundamental driver of global warming, environmental destruction, peak oil and natural gas, water and arable land shortages, social decay, resource wars, etc.
