Another widely discussed topic that deals with fairness is whether animal research is right or wrong. Sometimes when seeing animal research in TV-shows, I become really mad. Who has decided that the life of animal is less precious than ours? Do we really have the rights to govern their life in order to find cures?
If a dog has accidentally killed a man in self-defence, it has to be deceased. But when we use them as experimental animals, we might have to sacrifice at least 3 animals life before we have found the right cure, how can this be fair enough?
In the view of scientists, they think it is correct. Because there is no other way to find out how the cures work if they don’t be tested on living creatures, therefore animal is the only way. But how fair is it to animals?

THANKS FOR HELPING ME :D but I have got some questions:
Why can't I use "in the view of"?
Why should it be "aren't tested" instead of "don't be tested"?

Thanks again!
