@browncoat - I've heard of places like that too, but at least in those cases, it's pretty obvious what is happening and it's easy to avoid it.
But there are many places at the moment which are getting sinkholes, or might be about to, because they've simply used up too much ground water.
People just take water use for granted, but there is only so much to go around, particularly in places without a huge amount of yearly rainfall. And often water is taken from reservoirs under the earth much more quickly than it can replenish itself.
Sinkhole repair is going to be the least of people's worries in places like this. If it gets to the point where the earth itself is moving under their feet, they have probably used up the vast majority of the water and that's not something we've got an abundance of at the moment.
