"Three decades of rapid economic development in China has left a troubling legacy - widespread soil pollution that has contaminated food crops and jeopardized public health. Although they once labeled soil data a "state secret," Chinese officials are slowly beginning to acknowledge this grave problem"

"Along with air to breath and water to drink, soil is one of our most important natural resources. Without it we would starve. "

"Home to more than 50 million people, the Loess Plateau in China's Northwest takes its name from the dry powdery wind-blown soil. Centuries of overuse and overgrazing led to one of the highest erosion rates in the world and widespread poverty."

"Beyond Food Miles Posted Mar 9, 2011 by Michael Bomford NOTE: The following article is concerned strictly with the energy equation of the food sytem and is intended to stimulate questions about how best to grow, transport, store and prepare (ideally local) foods. There are many reasons to favor local food, including supporting local economies and building local food security.      "There is nothing as deceptive as an obvious fact" -Sherlock Holmes   A locavore is "a person who endeavors to eat only locally produced food."[1] What better diet could there be for an energy constrained world? After all, feeding Americans accounts for about 15% of US energy use,[2] and the average food item travels more than 5,000 miles from farm to fork.[3] It seems obvious that eating locally will go a long way to reducing food system energy use.   Yet cracking the case of America's energy-intensive food system demands that we look beyond the obvious. A local diet can reduce energy use somewhat, but there are even more effective ways to tackle the problem. Single-minded pursuit of local food, without consideration of the bigger picture, can actually make things worse from an energy perspective.[4]   If you realize you're spending too much money, the first thing to do is figure out where it's going. Cutting back on pizza won't make much difference if you're spending most of your money on beer. Similarly, the first step in reducing food system energy use is to figure out where all the energy is going. That's what a team of economists working for the United States Department of Agriculture (USDA) did last year, in a report called Energy Use in the US Food System.     Where the energy goes: Energy used in the food system as a proportion of total energy used in the US in 2002.[5]     The report contains some surprises. Transportation is the smallest piece of the food system energy pie. Even farming isn't a particularly big contributor. The big energy users t
