How the rainwater becomes acidic and its effect to plants animals humanbeing and metals?

If you have done 8th grade chemistry then you would have heard that some non metallic oxides like CO2 ,SO2 and P2O5 when diluted( put in aqueous solution) form acids like H2CO3 ,H2SO3 and H3PO4. Using this in real life when pollutants like carbon di oxide are released into the atmosphere they get mixed or diluted into water forming various acids.When the water evaporates and condenses it forms acid rain. Acid rain erodes rocks with certain minerals and largely limestone rocks
