Sustainability The problem is apparent at once. Reducing either P or A is completely contrary to the foundations of our religious and economic systems. We are given the impression by “experts” that both P and A must increase continuously if we are to have a “healthy society.” How small must P become to be sustainable? David Pimentel, a global agricultural scientist at Cornell University has estimated that a sustainable world population, living at the dietary level of the average American, is about 2 billion people. The world population in late 2011 is estimated to have reached 7 billion people and was growing at the rate of approximately 1% per year! The annual increase of world population in 2012 is thus something like 70 million per year. albartlett.org/articles/art_meaning_of_sustainability_2012mar20.pdf
