Hello samuel. Animal experiments are an unfortunate necessity in medical research. It would be good if we didn’t have to do use animals, but there are some potentially life-saving treatments that we can’t really test on humans. So long as the experiments are carefully controlled and ethically monitored to make sure there is no unnecessary suffering caused, I would be willing to work on animals.
I don’t work on zebrafish myself, but I know a few people who do. They make good models to observe animal development, because they have a transparent body, so we can see everything that happens inside. They also have a backbone, which makes them a lot closer to humans that some of the other organisms used to study development in the lab, like fruit flies or tiny worms.
If working with animals was going to save a million lives then I would do it. It would be a necessary evil if it meant saving lives or curing diseases. It’s always a tough decision to make though!
I don’t work with zebrafish but they are amazing creatures and i think we can learn an awful lot by studying them. I have some in my fish tank at home though 😀
