From Lester Brown, president of the Earth Policy Institute:
During the past two summers, Pakistan was hit with catastrophic floods. The record flooding in the late summer of 2010 was the most devastating natural disaster in Pakistanrsquo;s history. The media coverage reported torrential rains as the cause, but there is much more to the story. When Pakistan was created in 1947, some 30 percent of the landscape was covered by forests. Now it is 4 percent. Pakistanrsquo;s livestock herd outnumbers that of the United States. With little forest still standing and the countryside grazed bare, there was scant vegetation to retain the rainfall.
Pakistan, with 185 million people squeezed into an area only slightly larger than Texas, is an ecological basket case. If it cannot restore its forests and grazing lands, it will only suffer more ldquo;naturalrdquo; disasters in the future. Pakistanrsquo;s experience demonstrates all too vividly why restoring the earth is an integral part of Earth Policy Institutersquo;s Plan B to save civilization. Restoring the earth will take an enormous international effort, one far more demanding than the Marshall Plan that helped rebuild war-torn Europe and Japan after World War II. And such an initiative must be undertaken at wartime speed before environmental deterioration translates into economic decline, just as it did for the Sumerians, the Mayans, and many other early civilizations whose archeological sites we study today.
Our natural systems are the foundation of our economy. We can roughly estimate how much it will cost to reforest the earth, protect topsoil, restore rangelands and fisheries, stabilize water tables, and protect biological diversity. The goal is not to offer a set of precise numbers but rather to provide a set of reasonable estimates for an earth restoration budget.
