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.
I’ll be the crazy person. Where does meat come from, it not from murder?
Yeah, but that murder is worth it.
OK, so not crazy people then. Factual people to whom you won't listen. That's not really their problem.
Hard disagree, but each to their own.
