Why are Limestone structures eroded by acid rain?

Calcium carbonate + carbonic acid -> Calcium Salt + Water + CO2. This reaction has been responsible for the natural formation of limestone caves over millions of years, but more recently more acidic rain has been produce by the excess Sulfur Dioxide produced by burning Coal. SO2 reacts with water in the atmosphere to produce Sulphuric acid (H2SO4).
