Thank you very much. I want to thank our two presenters.
I want to pick up and follow on my colleague Terence Young's questions a bit, because he was asking a question, and I understand, Dr. Leszczynski, you didn't have these answers at your fingertips with regard to possible carcinogens that were moved off or down the list, but I think you gave your own examples at the very beginning.
What I heard you asking in your particular presentation, which I think is what we need to struggle with here as a committee, is this. Is there an ethical and moral need for us to look at a precautionary principle, or do we continue to follow what we saw with acid rain, with cigarettes, etc., where generations of people were harmed, died, got cancers, heart diseases, etc., and the ecosystem was destroyed by acid rain? What is the ethical duty of parliamentarians or people who are in charge of the health and safety of a nation or communities to have a consideration of not just the clear and definite evidence...? As Mr. Young and Dr. Tarzwell were saying, yes, there is some evidence but not all.
I think this is eventually an ethical and moral issue for us all. Do we err on the side of safety and precaution so that we do no harm or as little harm as possible, or do we wait for definitive studies?
You talked about that, but you didn't give me an answer about what you think is the moral and ethical duty of people like us, parliamentarians, who actually have to create, make legislation or regulations that would keep our citizens safe. You didn't answer that question yourself. You posed it a lot of times. I'd like to hear what you think.
