Paul and Anne Ehrlich recently offered what is likely the latest, carefully considered assessment of our chances of avoiding a collapse of civilization. It began with the publication of their findings in the Proceedings of the Royal Society B with a paper titled, “Can a collapse of civilization be avoided?” A summary of the findings was published on a blog of the Millenium Alliance for Humanity and the Biosphere (MAHB) hosted by Stanford University. I think you will find this assessment both interesting and sobering. Take a look at it.
