As fossil fuel prices rise, oil insecurity deepens, and concerns about climate change cast a shadow over the future of coal, a new energy economy is emerging. Wind, solar, and geothermal energy are replacing oil, coal, and natural gas, at a pace and on a scale we could not have imagined even a year ago. For the first time since the Industrial Revolution, we have begun investing in energy sources that can last forever. Plan B 4.0 explores both the nature of this transition to a new energy economy and how it will affect our daily lives.

Ever since 9/11, many have considered al Queda to be the leading threat to global security, but falling water tables in countries that contain more than half the world’s people and rising temperatures worldwide pose a far more serious threat. Spreading water shortages and crop-withering heat waves are shrinking grain harvests in more and more countries, making it difficult for the world’s farmers to feed 70 million more people each year. The risk is that tightening food supplies could drive up food prices, destabilizing governments in low-income grain-importing countries and disrupting global economic progress. Future security, Brown says, now depends on raising water productivity, stabilizing climate by moving beyond fossil fuels, and stabilizing population by filling the family planning gap and educating young people everywhere.

In this powerful and provocative manifesto, Bill McKibben offers the biggest challenge in a generation to the prevailing view of our economy. For the first time in human history, he observes, “more” is no longer synonymous with “better”―indeed, for many of us, they have become almost opposites. McKibben puts forward a new way to think about the things we buy, the food we eat, the energy we use, and the money that pays for it all. Our purchases, he says, need not be at odds with the things we truly value.

If the US continues with its current policies, the next decades will be marked by war, economic collapse, and environmental catastrophe. Resource depletion and population pressures are about to catch up with us, and no one is prepared. The political elites, especially in the US, are incapable of dealing with the situation and have in mind a punishing game of “Last One Standing.”

It often seems that different crises are competing to devastate civilisation. This book argues that financial meltdown, dwindling oil reserves, terrorism and food shortages need to be considered as part of the same ailing system. Most accounts of our contemporary global crises such as climate change, or the threat of terrorism, focus on one area, or another, to the exclusion of others. Nafeez Mosaddeq Ahmed argues that the unwillingness of experts to look outside their own fields explains why there is so much disagreement and misunderstanding about particular crises. This book attempts to investigate all of these crises, not as isolated events, but as trends and processes that belong to a single global system. We are therefore not dealing with a ‘clash of civilisations’ as Huntington argued. Rather, we are dealing with a fundamental crisis of civilisation itself. This book provides a stark warning of the consequences of failing to take a broad view of the problems facing the world and shows how catastrophe can be avoided.

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.
