Currently $ 19 in energy consumption in the United States (U.S.) used to manufacture and supply of food, so says David Pimentel and colleagues at Cornell University in the journal Human Ecology. Animal food products and junk foods require more energy in its production compared with vegetables, fruit and rice. To make one hamburger handfuls just needs at least 1,300 gallons of water, according to the U.S. Geological Survey. The study, by scientists from the University of Chicago, Gidon Eshel and Pamela Martin said that being vegetarian is very effective in saving energy.
"By reducing junk food and eat less meat, Americans can contribute a lot in fuel consumption and improve their own health," said Pimentel.
Small portion
Meanwhile, for those who have problems with eating habits, take it easy. Later people would eat in smaller portions. Why? The cost of food and energy sources that continue to swell as a result of global warming will make people eat less.
At least that prediction of the University of Illinois scientists to jacking the price of food in the future. Besides saving, reducing the size of the meal made for the health as well. Health care costs are also swell, making people forced to adopt a healthy lifestyle with diet.
Want to contribute in saving energy? Maybe it could start trying a diet. Originally it was not until malnutrition alone.
