Thank you very much, Madam Chair.
Thanks as well to the witnesses for being here with us today.
Mr. Schwarcz, you've been questioned a lot today in committee. At the very start of your presentation, you cited some very interesting facts. You said that some substances might be carcinogenic and that even small quantities of those carcinogens raised at times unfounded fears in citizens. You cited the example of California, where you've recently been. You said that excessive labelling might be counter-productive because, at some point, people became totally indifferent to the matter.
Despite my young age, I get the impression that everything has become carcinogenic in the past 20 years or so. We're discovering carcinogenic elements in everything. I don't believe that was previously the case. Scientific progress is definitely enabling us to make certain discoveries, but perhaps sometimes we go too far. We may not have enough scientific data to show that a substance is really carcinogenic. You're making the public aware of these issues on a radio program, if I correctly understood. Do you think there is a lack of information, of scientific data, and that it's not being sufficiently explained to people that certain substances may indeed be carcinogenic, but that quantities are so small they virtually have no impact on the consumer?
