Unlike clubs (as clearly demonstrated by TheBitterEnd's question) qualified caving leaders are required, as a matter of course, to make the topic of conservation an element of every beginner's trip they present, as per their BCA/NCA certification training. Club cavers have the same, if not greater (because of privileged access to otherwise restricted caves), responsibility towards conservation but since it is often the case that no-one fulfils a conservation role within them, it's hardly surprising that many members appear unaware of the hundreds of pages of conservation literature easily, and in most cases freely, available to them.
This results in an irony that, unlike proper cavers, professionally-led beginners are receiving consistently better education regarding the importance of protecting formations (debatably meaning they might be more useful as custodians of delicate environments than some pukka club members?).
QED, education does not protect caves since many cavers are totally uneducated in conservation.
