prevents the formation of acid rain which would otherwise react with limestone and cause calcium bicarbonate to form, which would easily dissolve away

Sulphur becomes sulphur dioxide when it is combusted. SO2 contributes to acid rain. Acid rain erodes limestone as it reacts with calcium carbonate.

Sulphur dioxide is released from burning fossil fuels. When Sulphur dioxide dissolves in water an acidic solution is formed.
This gas rises and dissolved in clouds eventually leading to acid rain falling.
Acid rains erodes limestone.
So if we reduce the amount of sulfur in fossil fuels would decrease the amount of acid rain therefore less erosion of limestone would occur.
