Study Claims Lettuce Is "Three Times Worse Than Bacon" For GHG Emissions (cmu.edu)
davidshenba writes: Sticking to a vegetarian diet may not the best for environment — in fact, it might be harmful to it. According to new research from Carnegie Mellon University, following the USDA recommendations to consume more fruits, vegetables, dairy and seafood is more harmful to the environment because those foods have relatively high resource uses and greenhouse gas emissions per calorie. "There's a complex relationship between diet and the environment," Ph.D. student Michelle Tom said. "What is good for us health-wise isn't always what's best for the environment. That's important for public officials to know and for them to be cognizant of these tradeoffs as they develop or continue to develop dietary guidelines in the future." As you might suspect some find the study dubious at best.
In fact, IF you'd THINK about the amount of energy used in collection, transportation, and preparation of a vegetarian diet, and consider how much you have to eat to get the calories and nutrition you need to survive then consider the calorie density of BACON, it's quite plausible that the entire process of putting bacon in your belly requires the generation of less greenhouse gases per calorie than it takes to put lettuce inside you.
Because calorie wise, 4 oz of bacon is like 4 KG of lettuce. And the lettuce still has no protein in it.

Obviously in your country it might be different.
In the US it seems 30% - 40% : http://www.worldfooddayusa.org...

Our digestive systems are not as good as cows' for processing that stuff.
See The Vegetarian Myth, written by a long term vegan/vegetarian.

Yes, but it's not orders of magnitude worse. To eat a cow, you have to grow it to the point where it's worth slaughtering before you cut it up and get some delicious sizzling steaks.
How many meals do you think the cow eats in that time?
Apparently they're slaughtered at between 3 and 16 weeks for good beef. How many meals do you think they eat in that time?
3-16 weeks? Cattle will be slaughtered at around 3 years age. Are you thinking of chickens?
