Strength in Numbers?

Been a little quiet on the blog lately but writing for a web magazine - Suite101 for which I recently published an article on global population growth. On NPR's Diane Ream show this week, guest Paul Ehrlich, author of The Population Bomb (1971) and more recently The Dominant Animal spoke on the implications of current trends in the fertility rate as the global population barrels along towards a whopping seven billion people. Certainly this is an issue of crucial importance, not only for the quality of life of those alive today, but, as Erlich points out, especially for those who come after us.
