If it has been proven.... Take the example of the aniline dye industry, where all of a sudden it seemed that all the workers there were getting bladder cancer. In the rat studies it didn't show that. You can give rats all kinds of things. Rats live in sewers and have livers that scoop stuff up and destroy it in a better way than humans.
If something has been implicated in cancer anywhere and I'm going to choose which sunscreen I want, why shouldn't I have the right to pick the one without the carcinogen, the same as people are making choices about genetically engineered food? If they don't want to be part of this big experiment, they should have the right to choose something that doesn't have it in it. If you take that little carcinogen, that little carcinogen, and this one and that one, we don't know whether all ten of them might make your body go tilt. It's not the one product; it's the fact that in a buffet of products we are choosing for our kitchens, bathrooms, and under our sinks, people want to know. They have a right to know what's in the products.
