Ruminants (cows, buffalo, goats and sheep) produce a total of about 16 grams of protein per day per capita globally. | |||
* 10 g protein/day per capita from milk{{x|from 297 mL/day of milk per capita}} | |||
* 6 g protein/day per capita from meat{{x|from 30 g/day of meat per capita}} | |||
* This was calculated in [[Code:food2.sql]]. | |||
Some of this food goes to waste, but there might be ways to [[food waste#mitigation|mitigate that problem]]. | |||
