Turning off all the electric appliances is very difficult now, but we can do it in our houses. Computers and lights are the tools that people who live in the city cannot live without, but some people do not turn them off when they do not use them. It not only damages the environment but also wastes the resources. People are very worried that if our environment is becoming worse and our resources are decreasing, it is possible that people will not live on the earth for a long time. The small action that we can do is turning electric appliances off when we do not use them.
