Reading for Understanding
1. Read the text and choose the headline:
a) Acid Rain Effects on Plants
b) Acid Rain Effects
c) Acid Rain Effects on Human Health
d) Solutions to Reduce Acidity
Acid rain has a negative effect on plants and animals. Once the acid gets into the water cycle it can cause the acidification of lakes and streams. The National Surface Water Survey (NSWS) identified over a thousand lakes and thousands of streams in the United States, where some form of acidification has taken place. Of these lakes and streams, 75 percent of the acidity in the lakes was directly due to acid rain. 50 percent of the streams had been affected by acid rain. Many areas of the Northeastern United States and Eastern Canada contain lakes and streams affected by acidification from acid rain.
Changes in the pH of lakes and streams affected by acid rain can result in a decrease in the variety of fish, plants and animals living in or near the water. Some animals and plants can not tolerate the higher levels of acid. Snails, clams and bass are examples of animals that can only tolerate a small increase in acidity.
Acid rain destroys trees and plants by causing damage to leaves and dissolving nutrients in the surrounding soil. Trees in higher elevations, have a greater risk for damage due to acid rain because they have greater exposure to clouds carrying sulfur dioxide and nitrogen oxide.
Acid rain can also have a devastating effect on man-made structures, such as those made of stone and metal. Bronze statutes and marble monuments are deteriorated by acid rain. Costly repairs and maintenance are required to clean acidic compounds resulting from dry deposition collecting on buildings.
One important misconception to clear up about acid rain is its direct harm to humans. Acid rain falls from the sky just like regular rain, without odor or taste. Acid rain is not directly harmful to humans. Yet, sulfur dioxide and nitrogen oxide are harmful pollutants before they combine with water and oxygen to form acid rain. These gases cause harmful particles that can be inhaled by humans, causing lung and heart disorders.

tolerate терпіти, виносити elevation висота
clam морської молюск devastating спустошливий,

bass окунь inhale вдихати
