If Americans started eating beans in place of beef the country would be able to meet its greenhouse gas (GHG) reduction goals by 2020. The report, title, “Substituting beans for beef as a contribution towards U.S. climate change targets,” builds off of previous work. The new report that makes this conclusion is similar to the conclusions from other papers; however, this report directly connects an easy dietary change to being able to avert catastrophic climate change. Previously we’ve seen how easy and beneficial it is to be vegetarian, but this diet change doesn’t require a complete shift to vegetarianism. Just reduce the consumption of flesh from dead animals.
It’s simple: the easiest thing you can do today to help the people of tomorrow is to eat less meat.
“The nation could achieve more than half of its GHG reduction goals without imposing any new standards on automobiles or manufacturing,” Sabate said.
The study, which was conducted while Harwatt was an environmental nutrition research fellow at Loma Linda University, also found that beef production is an inefficient use of agricultural land. Substituting beans for beef would free up 42 percent of U.S. cropland currently under cultivation — a total of 1.65 million square kilometers or more than 400 million square acres, which is approximately 1.6 times the size of the state of California.
Harwatt applauds the fact that more than a third of American consumers are currently purchasing meat analogs: plant-based products that resemble animal foods in taste and texture. She says the trend suggests that animal-sourced meat is no longer a necessity.
