Three-fourths of agricultural land is used to produce animal products, from which we get only 17% of our calories.

“Together with pasturing, three quarters of all agricultural land is thus being used to generate animal products (e.g. milk, meat, and eggs), while only one quarter is used for producing non-meat and non-dairy products, such as cereals, vegetables, tuber crops, and other plants."

“The benefits associated with livestock are societal, economic, and environmental. They contribute 17% to the global food balance, in terms of calorific intake per person per day, and 33% of the protein in human diets (FAOSTAT, 2008).”
