The US FDA says: "if a drug causes cancer in rats, we're not gonna certify
it for human use".  Remember Saccharin?  Because, if a chemical does 
do something nasty to animals, it'll *probably* do something equally 
nasty to human beings.  And "probably" is good enough.  And it's evil
(to use your terminology) to perform tests in that scale on human beings 
to find out for sure - Hitler's Germany did such testing.

And, in the case of things like Saccharin, it's extremely difficult to detect 
that a drug is doing nasty things.  Saccharin, (If I remember correctly) was 
guessed at being capable of causing a couple of cancers per *million* people.  
You want to do testing on humans on that big a scale?  How?  Or (as they do 
with rats) extremely high dosage testing for several generations?  If doing 
this testing on animals is unethical - what's doing the same on human beings?  
Don't give me any nonsense about tissue cultures or computers.  They simply 
*won't* catch problems that subtle.

OF COURSE, killing thousands of animals to determine that Chlorox is corrosive
is stupid and cruel.  But blanket condemnation of all animal testing is 
equally so (to the people suffering from the conditions the drug is being
researched in the first place).  Fortunately, most Universities have ethics 
committees that review test plans before allowing researchers to perform 
tests on animals or people.  Perhaps the cosmetics industry should be forced
to clear test plans with a government body that evaluates testing for
reasonability.
