Whatever their food is, 1kg of beef requires 24kg of grain’s worth of energy. This is something they teach in high-school biology now. The higher the food chain, the more energy is lost. Stopping such production would be pretty beneficial to the environment, but whether we should is a complicated question.
But as I pointed out, many cattle are ranched on land that cannot grow grain. They can’t grow the sorts of crops that humans eat, only the sorts of crops that cattle eat. If cattle weren’t being ranched on those lands they wouldn’t be producing edible grain instead, or any other food that humans could eat. So the inefficiency is moot when it comes to the amount of nutrition produced, removing the cattle from that land would simply reduce the total amount of food we have available.
Sure, if you remove the cattle then wild animals could come in to replace them, but we should make sure that’s not going to result in starvation and poverty if we do that. Many areas of the world have subsistence ranching by the locals.
Interesting. However, a search says that feeding all the grass (or whatever) to cattle takes that food away from existing ecosystems in dry areas and potentially allow exotic weeds to take over land. So we probably don’t want this to expand to the point where we intrude on dry ecosystems.
It’s just a matter of land management. Many of those grassland areas used to have other large grazing animals on them, so as long as the cattle herds aren’t bigger than those old herds it should be sustainable.
