Are vegetarians to blame for climate change? Researchers find lettuce is ‘three times worse than BACON’ for emissions…

  • Many common vegetables like lettuce require more resources per calorie
  • The study also found that they produce higher greenhouse gas emissions 
  • Researchers say relationship between diet and environment is complex 

Sticking to a vegetarian diet may not be as beneficial to the environment as you think — in fact, it might be helping to destroy it.

A study from Carnegie Mellon University has found that many common vegetables require more resources per calorie, and produce higher greenhouse gas emissions than some types of meat.

While lowering the weight of the general population has been shown to positively affect the environment, the researchers found that healthy eating leads to a higher environmental impact.

WEIGHING THE IMPACT

Researchers examined the food supply chain to understand the relationship between obesity in the U.S. and the environment.

They studied the impact of food from growing, processing and transporting, to food sales, service, and household storage.

Researchers also measured the changes in energy use, blue water footprint, and greenhouse gas (GHG) emissions.

Eating fewer calories and reducing the weight of the population leads to reductions in energy, along with a 9 percent drop in water use and GHG.

Eating these healthier foods, however increased the environmental impact.

Fruits, vegetables, dairy, and seafood contribute to a 38 percent increase in energy use, along with a 10 percent increase in water use, and 6 percent GHG emissions.

The study examined the impact of food from growing, processing and transporting, to food sales, service, and household storage, according to Carnegie Mellon.

Researchers also measured the changes in energy use, blue water footprint, and greenhouse gas (GHG) emissions.

‘Eating lettuce is over three time worse in greenhouse gas emissions than eating bacon,’ said Paul Fishbeck, professor of social and decisions sciences and engineering and public policy.

‘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.’

Michelle Tom, a Ph.D student in civil and environmental engineering and Chris Hendrickson, the Hamerschlag University Professor of Civil and Environmental Engineering examined the food supply chain to understand the relationship between obesity in the U.S. and the environment.

‘There’s a complex relationship between diet and the environment,’ says Tom.

‘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 trade-offs as they develop or continue to develop dietary guidelines in the future.’

Maybe the methodology is “impeccable” but the intellectual context is a huge obfuscation! Am I missing a joke here? If we’re going to “talk” about serious change, we should be talking about the internal combustion engine used in obscene redundancy by a spoiled rotten, but also “trapped” general public. Change the goddamned situation, idiots! By administrative fiat, “you” shall be issued a “chit” for your current vehicle. By a certain date (depending upon and coordinated with elements of the mandatory vehicle replacement program) your new electric vehicle will be ready for delivery, and your “chit mandated” old gasoline vehicle will be turned in for recycling. Etc. etc. But please let’s stop giving time and space to wasted idiocies like this Carnegie Mellon report. Again, the motivation for its funding is highly suspect!

1 – who paid for the study? (this should be asked of any study.)

2 – where is the impact from deforestation – primarily for the raising of meat?

3 – yes, animals raised in crammed spaces can be raised ‘efficiently.’ you are still torturing animals. would you torture your (or your friend’s) dog? why do you do it to cows and pigs?

4 – bloodlust is bloodlust. the reaction i get from most people when i tell the i am anti-war is outright hostility – all the more so after everyone around here voted obama and now, suddenly, war is just fine. same damn reaction i get from carnivores when i say i’m vegan.

5 – AGW is a scam. even if it were true, the policy of taxing a cornerstone of the lifecycle in order to create “global governance” is a sick farce. if it were really true, we’d be spending money on infrastructure.

What a crock. Where is the research supporting these claims? Looks like it’s written by someone who doesn’t know anything about climate change nor healthy eating…per calorie greenhouse gas? Come on, Dave. Look for credible evidence to back this up. It seems that the meat eaters are trying to justify their meat eating as causing no greenhouse gases. We are all smart enough to know this is false and there is a better way to be healthy AND save the planet…go vegan!

Well, we have the story on bacon and lettuce. How do tomatoes figure into the equation?

“The study also found that they produce higher greenhouse gas emissions.” So despite what they taught me about photosynthesis in grade school, plants are actually killing us with Carbon Dioxide? I wonder where the Oxygen Comes from then? This is as groundbreaking as it is ridiculous. Thanks for the laugh.
