A free-range steer grazing on ten acres of grass and slaughtered for meat kills one life form.
Ten acres plowed, harrowed, fertilized and otherwise cultivated for soybeans kills hundreds of thousands of worms, bugs, mice and other pests either through direct action or destruction of habitat.
I eat meat because it is kinder to my animal friends.
You are forgetting all the ticks, fleas, flies, horse flies, birds, chiggers, etc that live off of the steers you eat! lol
