This means that the cattle zoomass is now more than 50 percent larger than the anthropomass, and that the live weight of the two species together is very close to a billion tons. Even the largest wild mammals add up to only a small fraction of those masses: the 350,000 elephants in Africa, with an average body weight of 2,800 kilograms, have an aggregate zoomass of less than 1 million tons, which is less than 0.2 percent of the cattle zoomass. By 2050 there will be 9 billion people and, most likely, 2 billion cattle, together augmenting their already crushing dominance of Earth.
