For instance, suppose my cause is to prevent the growth of a hole in the ozone layer. I tell people they must stop using CFCs.
Well, that raises issues about just how serious a threat was the “hole in the ozone layer”, and how much if anything it had to do with CFCs.
Suppose for the sake of the example that it was a huge threat, caused purely by CFCs, but limiting CFCs (instead of stopping using them entirely) would have been enough to resolve the issue.
