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.
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.
