Why obese? I agree with your points on industrial production, but the only case where excessive fat is produced is in fat ducks and geese. Chicken, for example, are not reared to be overfat, but to have a lot of meat. BTW, this is mostly done by selecting and crossing breeds -- to a point where cruelty does intervene, imo, because some of the breeds they come up with are not viable in "real" circumstances and some can hardly walk... But your points upthread about weight etc, and this comment on obesity, don't seem to me right.
