The Earth is getting warmer because of the activities of people. We cut down and burn trees and send gases into the air with our cars and factories. Sure. We may not be leaders or scientists but we can play our part in protecting the planet. Here are two ideas.

Bike ,don't ride to school

Do you go to school by bus or by bike? If you bike, you are doing something for the Earth. Buses, cars,trains and planes produce a lot of carbon dioxide. If you live near to your school, why not bike there on warm spring mornings? 2

Wash the green way

Do you help your mom and dad wash clothes? Then wash them in an energy-saving way. When you wash clothes, wash them in cold or warm water to save energy , but not hot water. Wash your clothes when they fill up the machine. Some new ones use as less as one-fourth of the energy of older machines.

When the clothes are clean, dry them in the natural way, by hanging them on a line rather than (而不是)putting them in a dryer.

 4 For example , you can use it to clean the floor,water flowers, trees and so on. In all,you can cut the carbon dioxide used in washing by 90 percent.

If everyone pays attention to protecting the environment from himself,our earth will become more beautiful.
