I know that is a strong title, but honestly it is true. Eating meat is worse for the environment than driving an SUV. So, if you are driving around in a hybrid or other gas efficient vehicle for the environment (which I think is great), you should also go vegan.
"Which causes more greenhouse gas emissions, rearing cattle or driving cars? This question was posed in a recent report published by the United Nations Food and Agriculture Organization, which concluded the livestock sector “generates more greenhouse gas emissions as measured in CO2 equivalent—18 percent—than transport.”" - Satya Magazine
Satya magazine has an article this month about how being vegan is best for the environment, and at the bottom of this article is an excellent chart entitled "Do you eat like an SUV" which compares eating habits to driving certain types of vehicles. It is an excellent way to put this in perspective. So, please, go look at the chart. The article is a Q&A with authors of a study about eating and globa warming. Here is a link to the study.
Do it for the planet. Cut out the meat!
