Researchers at the University of Minnesota say large-scale adoption of “traditional” diets rich in fruits, vegetables and fish would mean lower volumes of greenhouse gases than the diet that commonly accompanies rising incomes around the world, with large doses of sugar, fat and red meat. If so-called Mediterranean, pescatarian or vegetarian diets were adopted widely, habitat destruction would be reduced greatly, they said. Professor David Tilman said ” this dietary shift would prevent the destruction of an area of tropical forests and savannas as large as half of the United States.”
