Antibiotics, insulin, vaccines for polio and cervical cancer, organ transplantation, HIV treatments, heart-bypass surgery - it reads like an A to Z of medical progress. But these major advances have something in common: they were all developed and tested using animals.
Animal experimentation is a contentious issue, but it boils down to two essential questions: does it work, and is it ethical?
The first is easy to answer: it works. Some would have you believe there are alternatives for all animal research, or that animal testing is always misleading and unsafe. These are fallacies.
Where there are reliable alternatives, of course, we use them - that's what the law demands. Magnetic resonance imaging, computer models and work on isolated tissues and cell cultures can be useful; but they cannot provide the answers that animal research can.
No one chooses to use animals where there is no need. It gives no one any pleasure, and it is time consuming, expensive and - quite rightly - subject to layers of regulation. Yet it is still the best way of finding out what causes disease, and of knowing whether new treatments will be safe and effective.
Biologically, we are similar to species such as mice and rats, because we have practically the same set of genes. Their bodies respond to disease and treatments much as ours do. If a genetically modified "purple tomato" can fight cancer in mice, as announced yesterday, it might work for humans, too.
Medical research is an arduous process. By the time a therapy reaches the patient, it is easy to forget just how important animals were in its development. Patients might not know that the powerful new drugs Avastin (for bowel, breast and lung cancer) and Herceptin (for breast cancer) were developed after research on mice.
In fact, animal research has contributed to 70 per cent of Nobel prizes for physiology or medicine. Without it, we would - medically speaking - be stuck in the Dark Ages.
It is not only drugs and vaccines. Just last week, researchers in Seattle announced that they had used an electronic brain implant to enable a monkey to move its paralysed limbs, a discovery with the potential to allow severely disabled people to regain movement.
I challenge anyone who has followed the tragic case of Daniel James, who committed suicide after becoming paralysed in a rugby accident, to try to stop research in the UK on spinal injuries, some of which involves rats.
Far from being ashamed of this kind of research, we should be proud of our scientists, whose work offers hope to those suffering from incurable disorders.
But what of the ethical issues? Some say that saving people from suffering is no excuse for the death of laboratory animals.
Those who object are entitled to refuse treatments that have been developed through animal tests - even if that means rejecting virtually every medical treatment that exists.
You got cancer, and you need a heart transplant to survive. The doctors think that they can give a heart transplant, but they never done it before. They want to try to do it on someone, but no one want to volunteer, and it became illegal to use animals to do experiments. They did it on you. You SURVIVED, for 1 month then you die. Do you want that to happen?
Animals and humans have different side affects to different things. You can not determine what humans are not able to used based of an animal correctly. Why be hypocritical by using animals if you're not going to use yourself. Hat makes you think that if you wouldn't want to be stuck with needles to benefit someone else's needs, then why stick an animal with no voice to speak.
Scientific experiments of the reasons for the development of science. We can discover some diseases and their cures.
First, experimenting on animals has led to some of the best scientific breakthroughs of our current age. The use of animal in scientific experiments removes the risks affecting the humans, it uses to find cures for some diseases or virus and test them.
On the other hand, some people say that animals should be kept not be used them in scientific experiments. It is not true because it isn't legal or ethical to perform scientific experiments on humans.
In my view, animals should be used in scientific experiments.
This is outrageous! Animal testing should be illegal. Yes, we may need to make a few sacrifices but think about what is morally right: rather than thinking whats best for us. As you said that monkeys are relatively the same as us, this means we should save them. Use them: not to our advantage, but to marvel at or discover new things about them. We are so lucky to have different species on our planet. Imagine a world without animals. The world would be begging to discover new life and other things. So instead of using them: killing them, let us be grateful for what we have. If they started killing us (let us pretend that they were superior) our lives would be tarnished and we could do nothing about it. Think about how they feel
You say that no one will volunteer to have an experiment done on them so instead you use animals. This is wrong because animals DO have a heart and an opinion, but they just can't say it as we do not understand them. Charles Darwin was the first discoverer of animals having feelings and Dawin was a very popular scientist with a lot of correct conclusions. I believe that animals should have the same rights as humans because we too are classed as animals therefore we are all equal.
