It’s now well-known that what we eat affects the environment. In the UK, the average person eats 122 grams of meat a day. This study found that, compared to diets containing over 100 grams of meat a day, a vegan diet produces 75 per cent less greenhouse gas emissions, requires 75 per cent less land, uses 54 per cent less water and results in 66 per cent less biodiversity loss.

A second study found how even moderate intakes of animal foods have a damaging effect. A vegan diet was found to have a 44 per cent lower environmental impact than the Mediterranean diet, which contained only a small amount of animal foods, equating to less than 11 per cent of calories.
