When I meet old friends and they ask, "How are you?" I often reply, "I'm fine; it's the world I am worried about." "Aren't we all" is the common response. Most people have a rather vague sense of concern about the future, but some worry about specific threats such as climate change or population growth. Some are beyond questioning whether civilization will decline if we continue with business as usual, and instead they are asking when this will occur.
In early 2009, John Beddington, chief science advisor to the U.K. government, said the world was facing a "perfect storm" of food shortages, water scarcity, and costly oil by 2030. These developments, plus accelerating climate change and mass migration across national borders, would lead to major upheavals.
A week later, Jonathon Porritt, former chair of the U.K. Sustainable Development Commission, wrote in the Guardian that he agreed withBeddington's analysis but that the timing was off. He thinks the crisis "will hit much closer to 2020 than 2030." He calls it the "ultimate recession"— one from which there may be no recovery.
These assessments by Beddington and Porritt raise two key questions. If we continue with business as usual, how much time do we have left before our global civilization unravels? And how do we save civilization?
In this urgent time, World on the Edge calls out the pivotal environmental issues and how to solve them now. We are in a race between political and natural tipping points. Can we close coal-fired power plants fast enough to save the Greenland ice sheet and avoid catastrophic sea level rise? Can we raise water productivity fast enough to halt the depletion of aquifers and avoid water-driven food shortages? Can we cope with peak water and peak oil at the same time? These are some of the issues Lester R. Brown skillfully distills in World on the Edge. Bringing decades of research and analysis into play, he provides the responses needed to reclaim our future.
