If they want to see what an IUD does to a human, they certainly have plenty of real humans who have already been injured to care for. Instead, in America anyway, they push them out the door and back into civilian life with little regard for their problems. So, as a veteran myself, I feel strongly that this is totally unnecessary and that real wounds can be treated by real doctors, not some eager corpsmen who want to justify their immature explosion passions by claiming they are doing it to save our soldiers.
Paladin, slaughtering animals for food is totally inefficient. There IS enough crop land to grow food for all living humans, but not if the humans insist on eating it in the form of meat. The inefficient model of converting crops to meat (I mean feeding then slaughtering livestock) before eating them is a huge loss. Estimates I've read indicate that a chicken is 1/16th as efficient a use of the crops and a steer uses as much as 50 times as much food to raise as you get from it. Not only that, humans are not anatomically evolved for a heavy meat diet. Our teeth and our colons are those of herbivores.
Jude, the people who did vivisections on prisoners in concentration camps were scientists, too. Being a "scientist" doesn't give you any insight on right and wrong.
Finally, pigs are very intelligent and caring creatures. They have a bad rap because they like mud, but even human children like mud. What's so wrong with that!?
