The study found that, compared to meat-heavy diets, vegan diets resulted in 75 percent less land use, 54 percent less water use, and 66 percent less biodiversity loss.
A vegan diet avoids all animal products, including meat, eggs and dairy.
Vegan diets had the lowest totals, accounting for 5.4 pounds of carbon dioxide a day.
In terms of land and water use and effects on species’ extinction, vegetarians, fish eaters and low meat diets had similar results.
The study also found that vegans and vegetarians were on average younger than fish and meat eaters.
