Peak Oil and Soil
When discussing the value of soil especially in the context of Peak Oil, the devil is in the details.
There are two parts to this: First is that readers may not realize the gravity of the situation concerning food and Peak Oil. There is a wing of the Peak Oil argument that statistically demonstrates how food presently can be said to be a form of oil. Numbers run as high as 10 calories of oil per calorie of food, which with 2,000 mile Caesar salads from California and 10,000 mile apples from New Zealand, is not hard to believe.
In fact, every step of the food chain rests entirely on oil and cheap energy: seed production and storage; plowing and planting via diesel tractors; irrigation of the desert by diesel pumps; fertilizer created from natural gas, without which tired fields that have no natural tilth or manure could not otherwise produce; pesticides and herbicides created from oil and applied with tractors; the harvest by diesel combine and shipped by semi from remote areas; the drying of grain or year-round cold storage; shipping by truck center to the mill and then the grocery where coolers and air conditioning with computer registers and just-in-time inventory again support the entire process.
In fact, there is less than a week’s supply of food in the entire food chain, while consumers—in contrast to America before 1960–hold less than a week’s worth of food at home in their refrigerators.
The “Green Revolution”, which ended the famines of the 70s, could arguably be said to be a result of eating oil. The logical conclusion is that without cheap oil, we must again return to those times, except with 1/3 more population.
