菜食主義の食事（vegetarian foods）における肉を食べる人よりも糖尿病（diabetes）になる人が少ないことや憂慮する科学者の会（the Union of Concerned Scientists）の研究結果、環境などの話です。
長いですが和訳をお願い致します。
Vegetarian foods are often praised for their health benefits.
Vegetarians usually have lower levels of heart disease, and studies have also shown that they have a lower risk of diabetes than people who eat meat.
What most people are less aware of, however, are the positive impacts that vegetarian foods have on the environment, compared to non-vegetarian foods.
Researchers from the Union of Concerned Scientists in the United States recently studied how consumer behavior affects the environment.
The study showed that meat consumption is one of the main ways that humans can damage the environment, second only to the use of motor vehicles.
So, how can eating meat have a negative effect on the environment?
For a start, all livestock animals, such as cows, pigs, and sheep release methane gas from their bodies.
One cow can produce up to sixty liters of this gas each day Methane is the second most common greenhouse gas after carbon dioxide.
Many environmental experts now believe that methane is more responsible for global warming than carbon dioxide.
It is estimated that twenty-five percent of all methane released into the atmosphere comes from farm animals.
