Over the past decade, renowned environmentalist Lester Brown has called for a worldwide mobilization to stabilize climate change, including a strategy for cutting carbon emissions 80 percent by 2020. With a look at recent geopolitics, Brown believes that food may be the issue that finally convinces the world to take the steps necessary to achieve this goal. He argues that we are entering a new food era, one marked by higher food prices, growing numbers of hungry people, and an intensifying competition for land and water resources. The issue of food security has become highly complex with every major environmental trend making humanity more vulnerable to food shortages: from climate change and population pressure to eroding soils and water scarcity. Brown joins the Council to share the newest edition of his strategy to address food insecurity, stabilize climate change and avoid environmental collapse: Plan B 4.0: Mobilizing to Save Civilization.
