Giving up meat and dairy in your diet could be the “single biggest way” to reduce your environmental impact on earth, a new study suggests. Researchers have found that while meat and dairy provide just 18% of calories and 37% of protein, it uses around 83% of farmland and produces 60% of agriculture’s greenhouse gas emissions. It also suggests that cutting these products from your diet could reduce food’s carbon emissions by up to 75%. We find out more from the lead researcher of the study, Joseph Poore, from the Department of Zoology and the School of Geography and Environment, at the University of Oxford.
