Of all our daily human activities, what we eat has perhaps the largest direct impact on the environment. Agriculture uses an estimated 70 percent of global freshwater to grow our food, and in the U.S., 22 percent of all our energy use is gobbled up by the food system. [In addition], the agriculture sector produces about a fifth of the world's greenhouse gases. A common myth is that the food system uses so much fossil fuel because we ship food around the globe. [But] our addiction to convenience foods" uses far more. From the making of fertilizer [to] running your refrigerator, the food system uses an enormous amount of energy. Not only are most of those fast and packaged foods higher in sugar and lower on nutrients. They are also wasting valuable energy resources. 'Conventional' food uses far more energy than organic [food does]. According to the Environmental Protection Agency, in 2007, U.S. agriculture used more than a billion pounds of pesticides. The USDA also reports farmers used 22 million tons of synthetic fertilizer in 2011. The amount of energy used to create synthetic nitrogen fertilizer (more than 13 million tons) could heat 5.5 million homes for a year. Junk food wastes money and precious resources. In 2013, Americans drank close to 39 gallons of soda per person (at a cost of about $150 per person), and in 2011, roughly 25 percent of the calories we consumed came from snack foods. And yet we willingly pay 1000 times more for that can of soda then what it actually costs. It turns out, it is not organic food that is the rip off.
