Beef farming, whether for meat or dairy is very intensive and, to my mind, inhumane in the US. I would probably have to be vegan if I went there.
In this country, and elsewhere these methods are being introduced, which is why all the meat I eat is organic, or raised to the highest welfare standards and, living in a quasi-rural area I can buy from local farmers. The meat and milk I eat comes from grass-reared cattle, who may be overwintered in barns, warmer, drier and healthier to being out in all weathers up to their hocks in mud, and destroying the pasture they use in the summer, and will be fed hay and fodder mainly grown on the farm they live on.
Some land, like high uplands and grade 5 land is not suitable for arable crops unless there is a high input of nitrogenous fertilisers. Grazing cattle and sheep is the best use of it and their droppings fertilise the flatter land so that occasional arable crops can be grown.
