Researchers have linked dietary data from over 55,000 individuals with data on the environmental impacts of the foods they eat. The team, from the Livestock, Environment and People (LEAP) project at the University of Oxford, found that the dietary impacts of vegans were around a third of those of high meat eaters. They also saw a 30% difference between high- and low-meat diets for most of the measures of environmental harm.
Industry also drives people’s demands fwiw, without lobbying, subsidy, advertising, and the cultural dominance of meat production those things have brought about, meat consumption wouldn’t be anywhere near what it is today
