When it comes to air quality, everything is connected. Acid rain cannot directly harm the human body, but the sulfur dioxide produced by acid rain can cause health problems. In particular, sulfur dioxide particles can promote chronic lung problems such as asthma and bronchitis. In addition, nitrogen oxides that produce acid rain promote the formation of ground-level ozone. While ground-level ozone helps block UV light, it promotes serious lung problems such as chronic pneumonia and emphysema.  When acid rain falls on a hill, acid rain produces a thick acidic mist that hangs low, obstructing vision and irritating the eyes and nose. Acidic fog also affects trees and plants, causing the leaves to turn brown and wilt.

“Limestone and marble are primarily composed of the mineral calcite (calcium carbonate), which dissolves readily in weak acid; in fact, this characteristic is often used to identify the mineral calcite.” This means buildings that are made out of limestone and marble, will be affected. Over time they may look worn down/ eaten away. A crust also forms on monuments and buildings made out of this, called gypsum. It's a reaction between calcite, water, and sulfuric acid that forms a mineral. Although the risk is low now, if humans continue to pollute and produce acid rain it may get to the point where the acid rain causes buildings to collapse and statues to erode past the point of recognition. This is why it is so important to help decrease the amount of acid rain in the environment. 

It is known that acid rain can leak into water systems, killing fish however, acid rain can also contaminate drinking water for humans. Poorer communities in other countries can bear the brunt of contaminated drinking water because a proportion of them collect rainwater for drinking purposes. If the acidity concentration in the water humans drink is too high it can cause brain damage over time.
