Thanks to Frank Götmark and his colleagues at The Overpopulation Project for their recent review of A Planet of 3 Billion.  We appreciate the thoughtful critique, 

While we prefer to the term “runaway population growth”, and prefer to first ask the question “How Many People Can The Earth Support”, seeking an thoughtful and considered answer, before invoking the term “overpopulation”, the work by The Overpopulation Project is thoughtful and deserving of a comprehensive review by anyone who is haunted by the implications of runaway population growth.  Their website is a treasure trove of thoughtful analysis.  Pleasure give it a measured read, even if you too avoid the term “overpopulation” when you approach this complex set of issues.
