How do you explain the reason for the change in rate at which limestone was lost?

The change in the rate at which limestone is lost can be attributed to various factors, including increased acid rain due to higher atmospheric CO2 levels, which accelerates chemical weathering. Additionally, human activities such as industrial emissions and land-use changes can exacerbate erosion rates. Seasonal variations in temperature and moisture can also influence the dissolution processes of limestone. Overall, these combined environmental and anthropogenic factors contribute to the variability in limestone loss rates.
