The last two posters don't know much about farming, especially organic farming which is the best and most sustainable kind. One piece of land can grow both plants and animals, because they are rotated. The food units 'wasted' by the animal are not wasted at all -they are returned to the land to increase its fertility for the next vegetable crop. The rotation means that both animal and vegetable pests fail to complete their life-cycles and do not become significant problems, avoiding the need for pesticides. The wonderful US organic farmer and poet Wendell Berry said that people who wish to divorce the animal and plant kingdoms, (as both chemical farmers and vegetarians wish), take a solution and split it down the middle to make two problems.
