I have a strong view that animal testing, if used in a humane manner, can be incredibly useful and important, as it may be able to save millions of innocent people.
For example, cancer kills 20,000 people every single day and if no cure is found, this figure will grow and grow. Unfortunately, we need animals to test on, however this animal will die for a very noble, worthwhile cause.
Overall,in my opinion, if it is for the right reasons, animal testing should be allowed.
