Are vegetarians causing climate change? Research conducted by Carnegie Mellon University concluded that eating a vegetarian diet contributes to climate change because fruit and vegetable consumption uses up more resources than meat diets.
In other words, the process of growing, distributing, and selling vegetables uses up global resources, and vegetables have very high greenhouse emissions per calorie. According to Paul Fischbeck, a professor and one of the researchers, “eating lettuce is over three times worse in greenhouse gas emissions than eating bacon.”
The researchers point out that it’s a complicated issue because healthier humans are good for the environment when compared to an overweight society that uses up calories and energy in larger amounts. The thing to remember, however, is that diets that are traditionally healthier and more fruit and vegetable-based simply use the most global resources.
The research was part of a study of the food-supply chain and the effect that obesity in the U.S. has on the environment. You can read the original article here.
