According to the report, based on figures from the United Nations' Food and Agriculture Organization, the production of one kilogram (2 lb 3 oz) of beef requires 15,455 litres (4,083 US gal) of water, cheese 5,000 litres, rice 3,400 litres, and carrots 131 litres.[2]
Over 75 kg (165 lb) of meat is consumed in the United States per person per year, 60 kg in Germany, 38 kg in China, and under 20 kg in Africa.[1]
Pigs can reach their market weight with 10–15 percent less food if they are kept on antibiotics, but overuse increases the likelihood of antibiotic-resistant bacteria, so-called "superbugs."[2]
