(30 POINTS)

Choose two pieces of evidence that support the author's perspective on pollution.

A) The types of pollution and their effects vary greatly. At the same time, however, they are related; each type of pollution affects the other types. An example of the connection between different types of pollution is acid rain.

B) Though pollution is everywhere, there are ways to help prevent it. By walking or riding bikes—instead of driving cars—people can help decrease air pollution. People can also buy and eat organic foods to support farmers that do not use fertilizers on their crops.

C) Acid rain is caused mostly by sulfur or nitrogen emissions given off by sources such as car exhaust and the burning of fossil fuels such as coal. These harmful chemicals rise into the atmosphere where they react with other compounds and then fall as an acidic form of rain, sleet, or snow.

D) Pollution has other effects, too. Breathing toxic air or drinking polluted water can cause humans and animals to develop health problems that can be serious and sometimes deadly. The deaths of too many members of a certain species of animal can upset the local ecosystem, or the area in which they live.

E) Unfortunately, pollution is like air: it’s everywhere! Pollution is the introduction of harmful substances into the environment that can cause damage and harm to humans, animals, and the environment. It takes on a number of different forms, from chemicals and garbage to something as seemingly innocent as light or noise.
