This was a member-proposed webinar organized by Stan Becker. The topic of the debate was:

•    "The population of humans that can be supported sustainably on the planet at a reasonable standard of living is below 4 billion." Yes or No.            
             
Four debaters took turns debating in favor of one of the two positions: Timothy Guinnane and Jacques Emina argued "No", while Anastasia Pseiridis and Frank Götmark argued "Yes”. The webinar was  introduced by IUSSP President Shireen Jejeebhoy and moderated by Stan Becker.  Joel Cohen offered some background to frame the debate and Suzana Cavenaghi provided a summary of the debate at the end.
