Study Claims Lettuce Is "Three Times Worse Than Bacon" For GHG Emissions (cmu.edu)

Posted by samzenpus on from the what-are-we-eating? dept.

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.

      The simple fact is that if animals weren't meant to be eaten, then they wouldn't have been made out of food. Besides, there is plenty of evidence that shows that animals are, in fact, delicious.

  2. The actual paper says nothing of the sort by burtosis · · Score: 5, Interesting

    The paper simply cites that on a per calorie basis many vegtables like lettuce, cucumbers, celery, etc are worse for the enviornment. It's actually obvious because these foods have no nutritional value with respect to calories, yet require water and other resources to bring to the table. The same paper states nutrition rich plant materials are actually better. The "debunking" article is just a knee jerking response and addresses "issues" that were never brought up in the paper. What we need to help fix this planet are people that run off of logic, not emotions.

    Let's focus on truly man made emissions, you know shit coming out of cars, coal plants, etc and stop trying to figure out how much a cow farts or how much is generated by eating lettuce. What a waste of time and money. All of the cows and lettuce eating people on the planet pail in comparison to one coal plant.

    Those cow farts are pretty much just as man made (and damaging) as your car when you look at a typical cattle (or chicken or hog) farm and the amount of mechanization that goes into turning grain and other feed into the meat in your supermarket.

    But in almost every case, the world's 1.5 billion cattle are most to blame. Livestock are responsible for 18 per cent of the greenhouse gases that cause global warming, more than cars, planes and all other forms of transport put together.
