Trend in gross world product to 2050 and what it implies for world average economic lifestyle

Excerpt from a talk I gave at OWPP/Cannon Design, Chicago, Environmental Awareness Week, October 2010. A projection of gross world product to year 2050 "leads to a world in which its average citizen has a per capita gross domestic product approximately equal to that of the average person in Japan or in the European Union today." (quote from my book, CO2 Rising, The MIT Press, page 126). The graph shown is figure 7.2, with data to year 2009. -- Tyler Volk, Professor of Biology and Science Director of Environmental Studies, New York University.
