Which risk greatly increases when excessive groundwater extraction collapses subterranean karst systems?

💡 Explanation

Significant groundwater extraction weakens the structural integrity, especially where dissolution has occurred; collapse leads to sinkhole formation because physical overburden exceeds reduced support. Without mitigation, surface failure is much likelier, rather than seismic shifts or water changes.
