What factors apart from acid rain could be killing trees?
Limestone, an underlying material for many soils, dissolves and corrodes when exposed to high concentrations of hydrogen ions. How is this information important in understanding the effects of acid precipitation?

Acid precipitation is considered severe if it falls below pH 4. Considering the pH of rainwater, how easy would it be to convert the rainwater to acid precipitation?

Carbon dioxide forms a weak acid called carbonic acid when dissolved in water. How can this be a significant factor in the formation of acid rain?

I'll give hints. 
Most of the ways to kill you can be used to kill the trees.
the rainwater is already acidic.
Because of carbonic acid.
