The Arithmetic of Catastrophe

Professor emeritus of Physics Dr. Albert A. Bartlett gives a lecture entitled "Arithmetic, Population, and Energy". Posted on YouTube as “The Most IMPORTANT Video You'll Ever See”, Dr. Bartlett makes the case that “The greatest shortcoming of the human race is our inability to understand the exponential function.”
We all have a blind spot for the impacts represented by seemingly small annual growth rates, particularly with regard to energy consumption and population. A 7% growth rate means doubling every 10 years. We are now approaching the limits of growth on this planet, yet we still praise the benefits of growth. Highly recommended. 80 min.
