Pork

Global average water footprint: 4800 litres of water for 1 kg of pork.

In an industrial pig farming system, it takes 10 months on average before a pig is slaughtered.
It produces 90 kg of swine carcass, 5 kg of edible offal and 2.5 kg of skin.
A pig consumes about 385 kg of grains (barley, corn, soybean meal, canola meal, wheat and other small grains and starch feed) and 11 cubic meters of water for drinking and servicing the farmhouse.
We need about 10 m3 of water during the slaughtering and cleaning processes.
To produce this feed we need 435 m3 of water.
This total volume of water is then distributed over the three major products based on their relative market values and product obtained per kg of live pig.
