Question: if the conditions are better than they used to b, why do you still oppose animal testing? Animal testing means that drugs can be tested without endangering human life, so what's wrong with it?

Because although the conditions are better they will never be the same as the animal would have in their natural environment. Being held in a laboratory will always have some stress attached to it especially when the experiments are then added to that.
You are right to say that animal testing is done to make sure that drugs are safe to go in to humans but the problem is that not all animal tests are really reliable because of the differences between humans and other species. So even if a drug is tested in animal it might still be unsafe in people because the animal is only an estimate of what will happen. My work involves looking for non-animal tests that would be better than what is done at the moment by being able to predict what happens in humans more accurately.
