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.
Rather than looking it as shifting the blame, could you not see it as another way in which you can make an impact?
We are where we are and we collectively need to reduce our environmental impact. Being conscious of what you eat is one way to do that, if you want to help.
