Full Planet, Empty Plates, Chapter 5: Eroding Soils Darkening Our Future

The thin layer of topsoil that covers the earth’s land surface was formed over long stretches of geological time as new soil formation exceeded the natural rate of erosion. Sometime within the last century, soil erosion began to exceed new soil formation. Now, nearly a third of the world’s cropland is losing topsoil faster than new soil is forming, reducing the land’s inherent fertility. Soil that was formed on a geological time scale is being lost on a human time scale.

Full Planet, Empty Plates: Chapter 2. The Ecology of Population Growth

Throughout most of human existence, population growth has been so slow as to be imperceptible within a single generation. Reaching a global population of 1 billion in 1804 required the entire time since modern humans appeared on the scene. To add the second billion, it took until 1927, just over a century. Thirty-three years later, in 1960, world population reached 3 billion. Then the pace sped up, as we added another billion every 13 years or so until we hit 7 billion in late 2011.

Rising Temperature Raising Food Prices

Over the last two months, the price of corn has been climbing. On July 19th, it exceeded $8 per bushel for the first time, taking the world into a new food price terrain. With heat and drought still smothering the Corn Belt, we may well see more all-time highs in coming weeks as the extent of crop damage becomes clearer.

World in Serious Trouble on Food Front

The world was hoping for a good U.S. harvest to replenish dangerously low grain stocks; this is no longer in the cards because of this Summer’s extreme weather. World carryover stocks of grain will fall further at the end of this crop year, making the food situation even more precarious. Food prices, already elevated, will follow the price of corn upward, quite possibly to record highs.

A Fifty Million Dollar Tipping Point?

By Lester R. Brown At a press conference on July 21, New York City Mayor Michael Bloomberg announced that he was contributing $50 million to the Sierra Club’s Beyond Coal Campaign. Michael Brune, head of the Sierra Club, called it a “game changer”. It is that, but it also could push the United States, and […]

Grain Production Falling as Soil Erosion Continues

The thin layer of topsoil that covers much of the earth’s land surface is the foundation of civilization. As long as soil erosion on cropland does not exceed new soil formation, all is well. But once it does, it leads to falling soil fertility and eventually to land abandonment. As countries lose their topsoil through […]
