The world stands at a crossroads. Either we continue on our path of environmental degradation, rapid population growth, and vast populations trapped in extreme poverty-or we choose international cooperation and sustainable development and avoid the cascade of global crises that will surely result if we do not. In this vital book, Jeffrey D. Sachs, one of the world's most respected economists, provides an analysis of our planet's plight that is deeply informed, profoundly disturbing, yet ultimately optimistic. Drawing on years of experience as economic advisor to governments and organizations across the globe, Sachs presents a new paradigm that offers practical solutions-and genuine hope for a crowded planet.
