In Australia 70% of the beef produced for human consumption comes from animals raised on grazing lands with very little or no grain supplements. At any time, only 2% of Australia’s national herd of cattle are eating grains in feed lots; the other 98% are raised on and feeding on grass. Two-thirds of cattle slaughtered in Australia feed solely on pasture. To produce protein from grazing beef, cattle are killed. One death delivers (on average, across Australia’s grazing lands) a carcass of about 288 kilograms. This is approximately 68% boneless meat which, at 23% protein equals 45kg of protein per animal killed. This means 2.2 animals killed for each 100kg of useable animal protein produced. Producing protein from wheat means ploughing pasture land and planting it with seed. Anyone who has sat on a ploughing tractor knows the predatory birds that follow you all day are not there because they have nothing better to do. Ploughing and harvesting kill small mammals, snakes, lizards and other animals in vast numbers. In addition, millions of mice are poisoned in grain storage facilities every year. However, the largest and best-researched loss of sentient life is the poisoning of mice during plagues. With its soft feet and low water use, kangaroo is a source of less ecologically damaging meat. No Dust Each area of grain production in Australia has a mouse plague on average every four years, with 500-1000 mice per hectare. Poisoning kills at least 80% of the mice.
