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 that this is our world. If we can tell 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.

The tourist industry is considered to be the largest industry. Before 1950, one million people traveled abroad each year but by 1990s, the figure had (46) to 400 million every year. Such large (47) of tourists; however, are beginning to cause problems. For example, on the Alps the climbers are destroying the mountains they came to enjoy. Even parts of Mount Everest in the Himalayas are reported to be covered (48) old tins, tents and foods that have been thrown away. But at a time (49) we have greater freedom to travel than ever before, more and more people are asking how they can enjoy their holidays without (50) problems by spoiling the countryside. Now there is a new holiday guide called “Holidays that don’t cost the earth”. It tells you how you can help the tourist industry by asking your travel agent before you go on holiday.
