Cornell researchers suggest we eat less. The average American consumes 3,747 calories a day. That's 1200-1500 calories more than recommended. It's the reason we're fat and unhealthy, while our planet is lean and unhealthy.
The problem is that American diets are larded in animals and in junk food. Both use more energy to produce than healthful staples like potatoes, rice, fruits, and veggies.
By eating less junk and less meat, the average American would have a massive impact on fuel consumption and his/her health.
The authors suggest moving towards more traditional, organic farming methods for meat and dairy. They suggest crop farmers reduce pesticides and use more manure, cover crops, and crop rotations for better energy efficiency.
Changing the way we process, package and distribute food would help too. Although apparently the single most dramatic improvement in energy use would come from you and me consuming less processed foods. On average, American food travels 1,500 miles before it gets eaten.
Try the Modern Commandments: 1) Buy local. 2) Support organic and sustainable farms. (Stop whinging about the price, you're going to buy and eat less.) 3) Eat mindfully and savor every nourishing bite.
