Unfortunately most of our caves likely rely on the hydrostatic pressure to keep the roof up...
It's not the years in your life that matter, but the life in your years.
Most of the water we pump out of the ground ends up in rivers that flow to the ocean, Even Agricultural irrigation has to have run off, without it salts build up in the soil from evaporation and that isn't good of course. It's a double whammy, we are polluting the soil and therefore ground water, and the flow through the aquifers is less which has the result in concentrating the pollution. How many think that the increase in nitrates and possibly phosphates is why the Mill Pond is overgrown with weed? I had never seen th eMill Pond more than a year or so ago, but some of the videos from a few years ago are astonishing at how weed free at least the swimming area was.
