in both the Karan and Bible, although the quotes are somewhat different. it states not only about not eating sick animals as leo9 so rightly said, but the main thing was, "its blood you must not eat" "this belongs to me". and so on. but misinterperating this is easy to do, as a lot of people dont believe in what any religious book says. at most all i see is religion causes more suffering to both man and animal, then any animal killing factory! unfortunatley its mans way again of making money, by mass slaughtering animals for the demand of the masses! its typical that yet again we see a goverment using propergander to fuse hate using peoples emotional consciousness! and they rise to the bait! even though they go out and buy meat, not knowing the horrors the animal suffered! i personally accept the "bolt method" this is far more "humane" then hallal. id prefer if offered to be put to death quickly rather than slowly. but again this whole thing is a mask, tensioning up an already unstable world!
i hope one day we wake up and become more friendly, towards animals. just like when all of a sudden, the world, [apart from a couple of nations] banned whalling!!
