Pollution comes from a variety of sources. In addition, it alters, changes, and even destroys a variety of places. For example,
exhaust from cars pollutes the air. When it rains, runoff from fertilizers and pesticides, which farmers use to help crops grow, can pollute the water in oceans, rivers, lakes, and streams. Garbage dumped in landfills is not only an eyesore, but also a source of harmful gases that can damage the earth’s atmosphere. Light pollution, which comes in the form of bright streetlights or signs, disrupts the view of the night sky. Noise pollution caused by cars, trucks, and machines interrupts the natural sounds of the world around us, such as birds singing or leaves rustling. Why are the fertilizers used by farmers bad for the environment?
A) They take up space in unsightly landfills.
B) They cause crops to grow and overtake land.
C) They enter into the water supply when it rains.
D) They can release harmful chemicals into the air.
