From Chester Peterson, Lindsborg, Kansas, US
Niall Firth writes that “livestock graze on a quarter of our planet's ice-free land.” Could all this land produce crops? Not my pastures. They support a stocking rate of only 2.8 hectares per “cow unit” – a 450-kilogram cow with late winter calf. Some US ranches must allow as much as 16 hectares. These cattle must have good legs: it can be a long way to water. They are the only way to “harvest” this land.
