A Vegan Diet Is the Best Diet for the Environment

It has been well established that what we eat affects planetary health. Compared to a meat-based diet, a vegan diet results in only 25% of greenhouse gas emissions, 25% of land use, 46% of water use and 34% of biodiversity loss, according to a new study published in the Nature Food journal.1 A vegan diet also has 44% less total environmental impact when compared to the Mediterranean diet, showing that even small amounts of eggs, dairy and fish in our diets have an environmental impact.2
