[1] The first Earth Day was in 1970. People were beginning to worry about what we were doing to our environment (环境). So they set up Earth Day to tell everyone about their worries.

[2] In 2007, organizers in over 150 countries planned over 4,000 big events. But Earth Day is not just about marches (游行) and big events. In the week around Earth Day (22 April) there were many thousands of smaller, local events. These events dealt with environmental problems in the neighborhood.

[3] The World Wide Fund for Nature made a list of 5 things that each person could do to save the environment.

·Don’t leave the tap running.

·Turn off lights when you leave a room.

·Turn off your computer every night.

·Wash your clothes, and yourself, in cold or warm water, not hot water.

·Dishwashers use as little water as possible.
