michael michael kors wallets michael michael kors wallets A Vegetarian Diet Is More Energy Efficient Than a Meat Diet



Vegan Diets Better for Environment



Both the burning of fossil fuels during food production and noncarbon dioxide emissions associated michael michael kors wallets with livestock and animal waste contribute to the problem, the University of Chicago Gidon Eshel and Pamela Martin wrote in the report.



The average American diet requires the production of an extra ton and a half of carbon dioxideequivalent, in the form of actual carbon dioxide as well as methane and other greenhouse gases compared to a strictlyvegetarian diet, according to Eshel and Martin. And with Earth Day approaching on April 22, cutting down on just a few eggs or hamburgers each week is an easy way to reduce greenhousegas emissions, they said.



neither make a value judgment nor do we make a categorical statement, said Eshel, an Assistant Professor in Geophysical Sciences. say that however close you can be to a vegan diet and further from the mean American diet, the better you are for the planet. It doesn have to be all the way to the extreme end of vegan. If you simply cut down from two burgers a week to one, you already made a substantial difference. Meanwhile, Americans also consume an average of 3,774 calories of food each day.



In 2002, energy used for food production accounted for 17 percent of all fossil fuel use in the United States. emit a lot of nitrous oxide into the atmosphere. A single pound of methane, for example, has the same greenhouse effect as approximately 50 pounds of carbon dioxide.



Thevegetarian diet turned out to be the most energyefficient, followed by poultry and the average American diet.



In their study, Eshel and Martin compared the energy consumption and greenhousegas emissions that underlie five diets: average American, red meat, fish, poultry andvegetarian including eggs and dairy, all equaling 3,774 calories per day.



Thevegetarian diet turned out to be the most energyefficient, followed by poultry and the average American diet. Fish and red meat virtually tied as the least efficient.



The impact of producing fish came as the study biggest surprise to Martin, an Assistant Professor in Geophysical Sciences. can be from one extreme to the other, Martin said. Sardi michael michael kors wallets nes and anchovies flourish near coastal areas and can be harvested with minimal energy expenditure. But swordfish and other large predatory species required energyintensive longdistance voyages.



Martin and Eshel research indicated that plantbased diets are healthier for people as well as for the planet.



adverse effects of dietary animal fat intake on cardiovascular diseases is by now well established. Similar effects are also seen when meat, rather than fat, intake is considered, Martin and Eshel wrote. our knowledge, there is currently no credible evidence that plantbased diets actually undermine health; the balance of available evidence suggests that plantbased diets michael michael kors wallets are at the very least just as safe as mixed ones, and most likely safer. Such farms typically provide the vegetables sufficient to support 200 to 300 families on plots of five to 10 acres. michael michael kors wallets
