From Vegetarianism: Wiki
"To produce milk from dairy cattle, calves are separated from their mothers soon after birth and slaughtered or fed milk replacer in order to retain the cows milk for human consumption. Vegans state that this breaks the natural mother and calf bond. Unwanted male calves are either slaughtered at birth or sent for veal production. To prolong lactation, dairy cows are almost permanently kept pregnant throughartificial insemination. After about five years, once the cows milk production has dropped, they are considered "spent" and sent to slaughter for hamburger meat and their hides. A dairy cow's natural life expectancy is about twenty years.
In battery cage and free-range egg production, unwanted male chicks are culled or discarded at birth during the process of securing a further generation of egg-laying hens."
So this makes me want to become a vegan. Even if I'm a vegetarian because of environmental reasons and not because of the meat industry............. ohhh but giving up banana yogurt and cheese sounds too difficult.
Ah I should not be reading wikipedia articles this late.
