The oil we eat: Following the food chain back to Iraq—By Richard Manning (Harper's Magazine) on 2009-05-18
-
Scientists have a name for the total amount of plant mass created by Earth in a given year, the total budget for life. They call it the planet's “primary productivity.”
-
humans, a single species among millions, consume about 40 percent of Earth's primary productivity, 40 percent of all there is.
-
-
two thirds of humanity's cut of primary productivity results from agriculture, two thirds of which in turn consists of three plants: rice, wheat, and corn
-
-
are able to store solar energy in uniquely dense, transportable bundles of carbohydrates. They are to the plant world what a barrel of refined oil is to the hydrocarbon world. Indeed, aside from hydrocarbons they are the most concentrated form of true wealth—sun energy—to be found on the planet
-
Agriculture was not so much about food as it was about the accumulation of wealth
-
Plants can spend their solar income in several ways. The dominant and prudent strategy is to allocate most of it to building roots, stem, bark—a conservative portfolio of investments that allows the plant to better gather energy and survive the downturn years
-
There is a very narrow group of annuals, however, that grow in patches of a single species and store almost all of their income as seed, a tight bundle of carbohydrates easily exploited by seed eaters such as ourselves
-
Under normal circumstances, this eggs-in-one-basket strategy is a dumb idea for a plant. But not during catastrophes
-
Corn, rice, and wheat are especially adapted to catastrophe. It is their niche
-
Farming is the process of ripping that niche open again and again. It is an annual artificial catastrophe, and it requires the equivalent of three or four tons of TNT per acre for a modern American farm. Iowa's fields require the energy of 4,000 Nagasaki bombs every year
-
A functioning grassland prairie produces more biomass each year than does even the most technologically advanced wheat field. The problem is, it's mostly a form of grass and grass roots that humans can't eat. So we replace the prairie with our own preferred grass, wheat
-
On average, it takes 5.5 gallons of fossil energy to restore a year's worth of lost fertility to an acre of eroded land—in 1997 we burned through more than 400 years' worth of ancient fossilized productivity
-
All the domesticates came from an area along what is now the Iraq-Syria-Turkey border at the edges of the Zagros Mountains. This is the center of domestication for the Western world's main crops and livestock, ground zero of catastrophic agriculture
-
The wheat-beef people swept across the western European plains in less than 300 years, a conquest some archaeologists refer to as a “blitzkrieg.”
-
Wheat is temperate and prefers plowed-up grasslands
-
The supply of temperate grasslands lies in what are today the United States, Canada, the South American pampas, New Zealand, Australia, South Africa, Europe, and the Asiatic extension of the European plain into the sub-Siberian steppes. This area largely describes the First World
-
Temperate grasslands make up not only the habitat of wheat and beef but also the globe's islands of Caucasians, of European surnames and languages
-
colonists in all of the neo-Europes enjoyed greater stature and longevity, as well as a lower infant-mortality rate—all indicators of the better nutrition afforded by the onetime spend down of the accumulated capital of virgin soil
-
In about 1960 expansion hit its limits and the supply of unfarmed, arable lands came to an end. There was nothing left to plow. What happened was grain yields tripled
-
tinkered with the architecture of these three grains so that they could be hypercharged with irrigation water and chemical fertilizers, especially nitrogen
-
In the forty-year period beginning about 1960, the world's population doubled, adding virtually the entire increase of 3 billion to the world's poorest classes
-
Ever since we ran out of arable land, food is oil.
-
The grinding, milling, wetting, drying, and baking of a breakfast cereal requires about four calories of energy for every calorie of food energy it produces. A two-pound bag of breakfast cereal burns the energy of a half-gallon of gasoline in its making
-
vegetarians can lose the edge in the energy argument by eating processed food, with its ten calories of fossil energy for every calorie of food energy produced
-
It takes thirty-five calories of fossil fuel to make a calorie of beef this way; sixty-eight to make one calorie of pork
-
Prairie's productivity is lost for grain, grain's productivity is lost in livestock, livestock's protein is lost to human fat—all federally subsidized for about $15 billion a year, two thirds of which goes directly to only two crops, corn and wheat

Co - incidently we are presently engaged in doing a
feasibility study on building a series of Barges with
this new, State of the Art, concrete tech.
-
I would consider reinforced concrete rather than Ferro-cement. So instead of a frame work of steel rods bound together, covered with chicken wire and then plastered to make it water tight, I would have a civil engineering company build me a standard concrete water tank of the required size.
