Yup, I have read studies of how the University of Minnesota and Wisconsin have been working on breeding cows with no legs. What do they need them for, right? Milk cows and beef cows don't use them because they have no need to walk. Not with factory farming. And who cares about the animal, because it's life is not it's own-it is going to be consumed or worn in the end.
I want to challenge you with this thought, however. Think of how your body operates when it is miserable and stressed-think of a lifetime of those elevated chemicals seeping into the muscle and fat of these animals, or milk. Wonder how hard it is to rid your body of metabolic wastes once the ability to move is taken away? Wonder what the effect of consuming the metabolic wastes and elevated cortisol levels of these poor animals will be? I guess we will see.
When it comes to the cloning of animals and the consumption of them-all we know is that any weakness that might occur from genetic engineering has not revealed itself yet. I can say that confidently because there is a lifetime of history behind any newly released drug or tampered food product that initially was to be as safe as water. I know that human beings want to figure all of this stuff out-it is why we have such evolved brains. But, there is a ripple effect in nature when we insert ourselves. That is an absolute truth. So we will see.
