That is what this pretty much boils down to...imprinting human feelings on what is an animal's life.
It is a fact that animals today are being genetically altered in their minds so that they no longer have the desire to do certain things, like walk. Many of these animals who have no feelings go insane because the mind tells them to do something and they are unable to.
If you look at a horse you can see, it wants to run sometimes, that is the way it is built, what it is designed for. If you look at any other animal you can see there are basic needs there. I don't expect someone to get all touchy feely about animals but a basic respect would be nice. They are living creatures just like humans, whether or not they can comprehend complex ideas or have deep feelings. If you take a horse and put it in a tiny cage that it cannot move in for any long period of time. It will freak out, its brain does not know how to handle the situation of not being able to function as it is designed.
It is the same for a chicken, cow, pig, what have you. They all have those basic desires to feel earth under their feet, to be able to walk around, to eat the kinds of food they were intended to eat. When you start messing around with that you are playing God. I would also go a step further and say you are desecrating one of God's creations. You are taking something that was intended to live one way, and forcing it to live a completely different way.
My problem is that I don't have a farmers market. Everything I buy comes from a store like WalMart. So I the consumer am a big part of the problem. I have to eat so becoming a vegetarian is about the easiest solution. Not that I don't like meat, I enjoy it very mutch. However if I want to try and make a difference and practice what I preach that is the easiest option I can see.
Animals don't really have a choice about what it eats. That has actually caused quite a few deaths in America that know of. In one case a 4 year old healthy boy died from eating meat that was tainted by a virus that exists in cows because they feed the cows corn now. Mad Cow disease exists because the company feeds cow back to cows. Sometimes it doesn't matter how you cook meat, it is poison one way or the other.
Many epidemics such as the bird flue exist only because the companies are forcing the animals into such disgusting conditions. We have created more diseases from how we process our animals now. But not to worry we have medical advancements that we can buy to make us all better. That is if you can afford them, otherwise you die.
