Well, even without industrial pollution, atmospheric carbon dioxide dissolved into clouds makes rainwater at least slightly acidic. Oh!But here in Indiana, a rain is almost ten times more acidic than natural rainwater.Why? Well, a lot of power plants and other factories that burn coal to make energy.Burning coal releases sulfur and nitrogen oxides into the atmosphere, which make rain more acidic.That does sound good! What would happen if you drink our rainwater?Nothing! The acid content isn't high enough to harm humans, and it doesn't affect the taste of the water, either.But acid rain can damage lakes, streams, and harm trees at high elevations.Also, acid rain accelerates the decay of buildings, statues, and sculptures.
