In this updated edition of the landmark Plan B, Lester Brown outlines a survival strategy for our early twenty-first-century civilization. The world faces many environmental trends of disruption and decline, including rising temperatures and spreading water shortage. In addition to these looming threats, we face the peaking of oil, annual population growth of 70 million, a widening global economic divide, and a growing list of failing states. The scale and complexity of issues facing our fast-forward world have no precedent

With Plan A, business as usual, we have neglected these issues overly long. In Plan B 3.0, Lester R. Brown warns that the only effective response now is a World War II-type mobilization like that in the United States after the attack on Pearl Harbor.

The world faces numerous environmental trends of disruption and decline such as rising temperatures, falling water tables, shrinking forests, melting glaciers, collapsing fisheries, and rising sea levels. In "Plan B," Lester R. Brown notes that in ignoring nature's deadlines for dealing with these environmental issues we risk the disruption of economic progress.

In addition to these environmental trends, the world faces the peaking of oil, the addition of 70 million people per year, a widening global economic divide, and the spread of international terrorism. The global scale and growing complexity of issues facing our fast-forward world have no precedent.
