Katherine Luck 3/3/2008 5-8 The Oil We Eat Richard Manning Conservation of energy is not an option, it is a fact. Plants have the unique ability to turn sunlight into stored energy in the form of carbohydrates – basic fuel of all animals Photosynthesis is the only way to make this fuel Humans consume 40% of Earth’s primary productivity. Extinction rate is 1,000 times that which existed before human domination of the planet. Energy cannot be created or canceled, but can be concentrated. More than 2/3 of humanity’s cut of primary productivity results from agriculture, 2/3 of which in turn consists of three plants: rice, wheat, and corn. These plants are able to store solar energy in uniquely dense, transportable bundles of carbohydrates. Agriculture is a recent human experiment, it is nor so much about food as it is about the accumulation of wealth/ Domestication was also a radical change in the distribution of wealth within the plant world Corn, rice, and wheat are adapted to catastrophes including floods. Iowa: almost all fields now, little prairie remains. A functioning grassland prairie produces more biomass each year than does even the most technologically advanced wheat field. It’s mostly a form of grass and grass roots that humans can’t eat. Oil is annual primary productivity stored as hydrocarbons, built up over many thousands of years.
