No to Population Growth

Today, in a New York Times Letter to the Editor, I challenge investment strategist Ruchir Sharma's assertion that slow population growth is to blame for a lagging U.S. and global economy. Sharma's shortsighted perspective fails to look at the disastrous impacts of ongoing population growth on our already overstressed global environment. I further argue that, with the growth of a global middle class, or "consuming class," humanity's carbon footprint is destined to expand well beyond what sheer population trends suggest, exacerbating health-threatening air pollution in Asian mega-cities and deepening water crises that threaten security in already tempestuous parts of Africa and the Middle East. Sharma is chief global strategist for Morgan Stanley Investment Management.
