By looking at environmental events, such as beach closings or smog alerts on hot summer days, students discuss the human causes of such events. They then draw a poster or sign to indicate how they might encourage others to become more environmentally friendly. During the summer, many people suffer breathing and respiratory problems, or have burning, watery eyes.
Beaches are closed.
UV readings are now a regular part of weather reports. Rainwater is much more damaging to cars, buildings, and other structures with stone or metal surfaces. High bacteria counts in water due to pollution such as sewage and other types of materials close beaches. Low ozone levels allow more damaging ultraviolet rays to reach the earth's surface, causing burns and cancers. Acid in water eats away at surfaces of metals, wood, and stone.
