Lettuce 'three times worse' for environment than bacon, new study says

Lettuce 'three times worse' for environment than bacon, new study says - SFGate:
"Meat-lovers, prepare to shove this in the face of all your vegetarian friends.
According to a new study from Carnegie Mellon, a vegetarian diet could be worse for the environment than a carnivorous one. 
Only pork chops can save the ozone now!
Fruits, vegetables, dairy and seafood have a more negative impact on the climate than meat, claims the study.
The meat-less diet increases energy use by 38 percent, water use by 10 percent and greenhouse gas emissions by six percent. 
"Eating lettuce is over three times worse in greenhouse gas emissions than eating bacon," Paul Fischbeck, professor of social and decisions sciences and engineering and public policy, told Carnegie Mellon.
"Lots of common vegetables require more resources per calorie than you would think.
Eggplant, celery and cucumbers look particularly bad when compared to pork or chicken."
The study set out to discover if the obesity epidemic in America is adversely affecting the environment.
While it's true that losing weight and eating fewer calories reduces energy use, the USDA's recommendations for healthy eating (lighter on the meat, heavier on fruit and veg) isn't necessarily the best thing for climate change."
