Eating Less Meat 'Like Taking 8 Million Cars Off the Road'

"Having big U.K. meat-eaters cut some of it out of their diet would be like taking 8 million cars off the road," reports the BBC:That's just one of the findings of new research that scientists say gives the most reliable calculation yet of how what we eat impacts our planet. The Oxford University study is the first to pinpoint the difference high- and low-meat diets have on greenhouse gas emissions, researchers say... [Oxford University] professor Peter Scarborough, who is part of the Livestock Environment And People project surveyed 55,000 people who were divided into big meat-eaters, who ate more than 100g of meat a day, which equates to a big burger, low meat-eaters, whose daily intake was 50g or less, approximately a couple of chipolata sausages, fish-eaters, vegetarians and vegans... The research shows that a big meat-eater's diet produces an average of 10.24 kg of planet-warming greenhouse gasses each day. A low meat-eater produces almost half that at 5.37 kg per day. [Fish diet: 4.74 kg. "Vegetarian" diet: 4.16 kg] And for vegan diets - it's halved again to 2.47 kg a day. The analysis is the first to look at the detailed impact of diets on other environmental measures all together. These are land use, water use, water pollution and loss of species, usually caused by loss of habitat because of expansion of farming. In all cases high meat-eaters had a significantly higher adverse impact than other groups... A separate study also published in Nature Food in 2021 concluded that food production was responsible for a third of all global greenhouse gas emissions. And an independent review for the Department for the Environment Food and Rural Affairs (Defra) called for a 30% reduction in meat consumption by 2032 in order to meet the UK's net zero target. "The meat industry said the analysis overstated the impact of eating meat." Thanks to long-time Slashdot reader beforewisdom for sharing the article.
