Florida’s bedrock is limestone, which is naturally prone to being slowly dissolved by the slight acidity of rain and surface water. This makes many areas of the state vulnerable to sinkholes, with little that can be done to assess the specific risk without expensive geological testing. On the whole, Florida’s hurricanes and tornadoes do far more damage than sinkholes, while bad driving from illegals and retirees is the greater everyday hazard for Floridians.
Fracking’s fault.
