We know how many people the earth can support

A quarter century after Joel Cohen asked the essential question “How Many People can the Earth Support?”, this article offers an answer, based on new science and geographical analysis, and asserts that we have long ago exceeded our planet’s long term ecological carrying capacity that optimistically...
