Less Is More: On Population, More or Less

The United Nations forecasts that by 2050 the world’s population will exceed 9 billion. How will that affect life on the local level, on the global level, and in developing countries? And what impact will all these new humans have on the climate? Last week on Sea Change Radio we talked with Paul Ehrlich, iconic authority on the subject of population. This week on Sea Change Radio, we continue our exploration of the topic. First, host Alex Wise speaks with New York Times environmental reporter and Dot Earth blogger, Andrew Revkin, and then later with Stewart Brand, frequent guest, former student of Paul Ehrlich, and environmentalist icon in his own right. Both guests share their thoughts on how immigration, urbanization, religion, and the increasing global empowerment of women are affecting the population equation. And for more on the ongoing debates surrounding population, check out Mr. Revkin's recent posts here and here via Dot Earth.
