Planet Earth Challenges

August 30th, 2005 · No Comments

Scientific American has a special issue (Sep 2005) focused on the challenges facing us: “Three great transitions set in motion by the Industrial Revolution are reaching their culmination. After several centuries of faster-than-exponential growth, the world’s population is stabilizing. Judging from current trends, it will plateau at around nine billion people toward the middle of this century. Meanwhile extreme poverty is receding both as a percentage of population and in absolute numbers. If China and India continue to follow in the economic footsteps of Japan and South Korea, by 2050 the average Chinese will be as rich as the average Swiss is today; the average Indian, as rich as today’s Israeli. As humanity grows in size and wealth, however, it increasingly presses against the limits of the planet. Already we pump out carbon dioxide three times as fast as the oceans and land can absorb it; midcentury is when climatologists think global warming will really begin to bite. At the rate things are going, the world’s forests and fisheries will be exhausted even sooner…These three concurrent, intertwined transitions–demographic, economic, environmental–are what historians of the future will remember when they look back on our age. They are transforming everything from geopolitics to the structure of families. And they pose problems on a scale that humans have little experience with. As Harvard University biologist E. O. Wilson puts it, we are about to pass through ‘the bottleneck,’ a period of maximum stress on natural resources and human ingenuity.”
