Thank you very much.
I'm going to go back to Professor Ariya. I'm very intrigued by the evidence you gave. Some of our discussion has been focused on bigger issues like climate change that don't necessarily inform our CEPA study directly. By the way, I do agree with you on cap and trade.
I would like to go back to Mr. Bossio's question, which was raised in previous panels, about the emergence of computational methodology to dramatically improve our ability to assess very large datasets. I'm not sure it necessarily directs us whether we should go to a hazard-based model or a risk-based model. I think a risk-based model can be dramatically improved as this methodology takes root. I would be interested to hear a little bit more about how computational methodology is going to improve our ability to get it right for Canadians, to improve the health and safety of Canadians.
