It’s easy to exaggerate problems as well, so we have to be very cautious. We have to always preserve our integrity as scientists. Even though we were advocates in terms of trying to get society to do something about it, we had to continue with honesty, in terms of how to express these fears, for example, to the news media. It’s easy to try to exaggerate the problems just to get more attention. So for me, it was very clear that the best way to deal with that was to do the best science that I was capable of doing. Furthermore, to try to distinguish clearly when I was talking as a scientist, in contrast to talking just as a person with value judgments, in terms of thinking that society should do something about it, but that’s not necessarily the scientific issue. That’s more a conviction issue.
