Hey I'm all for making agriculture humane and to end needless suffering. I'm just saying there's got to be a point on the ethical scale where farmed animals are better off than they would have been in nature. I live around massive cattle operations, and they are absolutely in every way possible better off than a bison wondering the Serengeti. If only because they can drink water whenever they want and never fear a giant croc will drag them into the water to be drowned.
And yes, pig and chicken operations like that should be stopped.
