57 Billion People and Counting…
To the one half of the world who live on less than 2-dollars a day (they receive 300 times less per capita energy than the US citizens) the world must look extremely overpopulated with an effective population of 57 billion! [The EU27 with per capita GDP of $29,900 would account for 21 billion and the United States—per capita GDP of $43,223—for 18 billion of the total effective population.]
