Over the last twelve years the world's population has grown by one billion and has now reached seven billion people. Ona Radtke describes and analyses the causes and consequences of this unbridled growth, which has long accompanied human history as a central theme, but has rarely been thoroughly questioned. This author believes that overpopulation has always been the main source of discord, poverty and war, affecting all facets of life. Now, after many years of extensive travel and observation, he is calling for an increase in consciousness and for redirection. The book includes an interview with the author, a biographical outline with accompanying photos, and a postscript by Professor Wolfgang Lucht of Potsdam Research Institute for Climate Impacts and the Geographic Institute of Humboldt University, Berlin.
