I don't killing animals is immoral, so no. What I'm saying is that vegetable/wheat farming kills a lot more animals per pound of food, than a feedlot does.
Therefore, if one does find killing animals in order to eat to be immoral, they have few options other than starving to death.
A feedlot feeds corn or wheat to animals who are then consumed by humans. There are therefore two levels of cost: first the production of the grain feed and second the raising of the animal.
I am a vegan for health reasons, so I look at this two level procedure in meat production from an economic standpoint. Meat production is a huge waste of economic resources, more than doubling the cost of producing the same nutrients in vegetable form.
Here is a simple complete human diet: pasta and lentils, plus four pills per day (multivitamin, B12, calcium carbonate and Omega 3/6/9).
