so why do they keep getting caught in those traps baited with it?
Apparantly, the favourite food of a mouse is peanut butter, unless they are mice from Birmingham, in which case they prefer chocolate. wierd huh?
ok - i apologise for what is basically an essay that follows, but here goes:
Anyway - back regarding the animal testing thing:
99% of all drugs that are invented fail at the animal testing stage, for whatever reason; often they cause abnormalities in offspring, or injury/death to the subject animal. Obviously there are other reasons why a drug can fail - it might be found not to actually do anything. Nevertheless, most drugs fail due to the side effects they cause, that are detected by animal testing.
In addition, I beleive its something in the region of 90% of drugs fail at the human testing stage.
Let us imagine a hypothetical situation where all animal testing for drug research has been banned. There are thousands of drugs in production at the moment. If we imagine that there are only 5000 drugs being produced in the world (i have no idea exactly how many there are, but its definately more than this), then lets do the maths.
5000 x 9 = 45,000.
This is how many drugs fail in the human testing stage. This means that there are 50,000 drugs (including the 5000 that do pass the human testing stage) that pass the animal testing stage.
This is 1% of all drugs produced. so the other 99% of drugs fail. this is:
50,000 x 99 = 4,950,000 failed drugs
Im not sure how accurate this number is, but bearing in mind the facts ive been given, i must assume that it is correct.
if we had no animal testing, then we would have to try all of these drugs out on humans. Bearing in mind that most of these drugs will have horrible to fatal consequences, we're talking about destroying the lives of 4.9 million people. This is a significantly larger number than the entire population of scotland. If youre scottish, imagine everybody you know either very ill, dead, or with deformed children.
The drugs we produce save many millions of more lives than that every year.
Then bear in mind that it takes several test to sometimes detect problems with drugs. Thalidomide has already been mentioned. the majority of mothers using Thalidomide had no problems with their babies, yet there was a small percentage that did, which resulted in hundreds of congenitally malformed babies. Thus to test for possible problems with a drug, many subjects must be tested on for each drug. This means that probably each drug must have at least 100 subjects to test on, maybe more, to maintain experimental validity.
This leads to 100 x 4,950,000 = 495,000,000 subjects at the least. Admittedly that is spread out over many years, but nevertheless if we're talking people instead of animals, thats almost 1/12 of the entire current population of the world that we would have to use for experimentation.
As i think i've demonstrated, we cannot test on humans. So the only choice we have is to test on animals, or not to have any drugs.
If you beleive that each animal life is worth the same as a human life, then I can see why you might not want to use this huge number of animals (and these are conservative estimates at best) for testing purposes. If you dont feel that an animal life is worth that of a human life, then surely in order to save lives, then we have to experiment on animals.
Your choice. Maybe people who are against animal testing should not useany drugs that are tested on animals. In that way it would be similar to vegetarianism - if you dont beleive in using animals, then dont use the products you get from them. Of course, that means no drugs that have been developed in the last 50years....
