Today, the human diet, especially that of Westerners, revolves around meat.Livestock products provide one third of humanity’s protein intake. In Australia livestock production is a critical export industry and contributes to high domestic consumption of meat products. According to a 2005 report from Australian government research agency, the CSIRO, an average Australian eats 35 kg of beef, 21kg of pork, 36 kg of chicken and 13 kg of lamb each year – roughly 290 g of meat per person, per day. To satisfy the meat requirements of Australians takes 16 million sheep, 8 to 9 million head of cattle, 5.6 million pigs and nearly half a billion chickens.

There’s a central reason we eat so much meat: it’s a great source of protein, iron, zinc,vitamin B12 and long-chain omega-3 fatty acids. But there are other, perhaps less well known, facts about meat consumption. The U.N. Food and Agriculture Organisation found that livestock are responsible for 18% of global greenhouse emissions – more than transport. Feeding and watering livestock accounts for over 8% of global human water use. Of the total combined weight of land-based animals, livestock makes up 20% and livestock displace native species and cause significant erosion problems.
