I'm in the middle or writing an essay for school on Animal Testing. When I originally agreed to do the subject, I wrote up a list of points I was planning to cover. Now, however, I can't seem to remember what I was thinking when I wrote one of them down. I meant to mention an instance or two of sacrifice 'for the greater good', as corny as that sounds. Could someone please tell me of a few of such instances? Anything in which a small group died or suffered so that a larger group wouldn't.
