It’s a conscious decision that Sherry Rowland and I did, not just to communicate our findings to other scientists, but to actually try to do something about it. In some sense that was taking a risk. Of course, the signs of the ozone layer and the effects of industrial chemicals was not nearly as well established at that time as it is now. We were just convinced that it was very important to find out. On the other hand, we were taking a risk, in that it’s not a normal role expected of scientists. Our peers were perhaps questioning whether we were just seeking publicity or not. But again, we thought it was not important enough just to preserve our image in the scientific community, compared to what we really thought we had to do, which is to find out more about the problem and let the governments know more about it, so that eventually some action could be taken. And that’s indeed what happened.
