You probably hear a lot about the environment. But do you really worry about it? Do you help to save the Earth? Cleaning a planet is not a task for only one person. People everywhere have to get involved and understand this is our world. If we pass the world about the importance of reducing, reusing and recycling, the destiny of this planet can change. Reducing the amount of waste you produce is the best way to help the environment. Did you switch off the water while brushing your teeth in the morning? You should do it! Did you walk to school or did you use public transportation? Reusing is another way of being environmentally friendly. Try to find ways to use things again! Take cloth sacks when you go shopping instead of taking home newspaper or plastic bags. You should use cloth sacks again and again. You have to save some trees! Shoe boxes and margarine containers can be used to store things or become fun art projects. Use your imagination! You can also recycle in your home or even at school. Many communities have recycling centers for newspapers, batteries and a variety of glass and plastics. These can be made into new products. 28.
