Quarrying obviously destroys intercepted cave passages.
Pollution from run-off liquids, or dumped refuse, doesn't threaten the cave as such but could pollute water flowing through it and emerging from springs at a lower altitude - a serious matter if the spring is someone's water-supply.
Smaller-scale threats are vandalism, including litter and graffiti, the theft of stalagmites etc. and the trampling of flowstone or sediment exposures. The last threat is usually more from ignorance than anything.
A problem faced by show-cave owners is that of "lampenflora" (german, lit. "lamp flora!) - algae and fersn growing in the light from the flood-lamps. It arrives as spores borne on air-currants or on visitors' clothing. It may look pretty, superficially, but is not part of the cave's natural ambience, and many show-cave managwers now take steps to minimise the problem.
Whilst not a human threat to caves per se, White Nose Syndrome, a fungal infection, is ravaging the bat populations in caves and elsewhere in North America. Cavers, national park officials etc are doing what they can to avoid spreading the spores by human means, but the bats are their own, unwitting, worst enemy. They are herd animals and fly from cave to cave according to environmental conditions suiting the bats' differing needs in hibernaculae, day-roosts, mating-swarm accommodation and nurseries.
