Dairy farming is based on forced pregnancies and killing calves. To supply milk that should be for calves to millions of humans requires cows to be continually impregnated, and their calves to be taken from them. The male calves are used for veal -- and will soon be killed. If calves (male or female) don't appear healthy, they are killed at birth. No matter how idyllic farming appears to be, it is inherently cruel.
