Post Carbon Fellow William Rees was quoted in “Op-Ed: Collapseologists are warning humanity that business-as-usual will make the Earth uninhabitable,” an opinion piece in the Los Angeles Times.

From the article:

Among the signatories of the warning was William Rees, a population ecologist at the University of British Columbia best known as the originator of the “ecological footprint” concept, which measures the total amount of environmental input needed to maintain a given lifestyle. With the current footprint of humanity — most egregiously the footprint of the energy- and resource-entitled Global North — “it seems that some form of global societal collapse is inevitable, possibly within a decade, certainly within this century,” Rees said in an email.
