When you enter a supermarket, you see shelves full of food. You walk between the shelves. You carry a shopping basket with your food in it.
You probably hear soft, slow music as you walk between the shelves. If you hear fast music, you walk quickly. The supermarket plays slow music. You walk slowly and have more time to buy things.
Maybe you go to the meat department first. There is some meat on sale, and you want to find it. The manager of the supermarket knows where customers enter the meat department. The cheaper meat is at the other end of the meat department, away from where the customers enter. You have to walk by all the expensive meat before you find the cheaper meat. Maybe you will buy some of the expensive meat instead of the meat on sale.
The department selling milk and milk products such as butter and milk powder is called the dairy department. Many customers like milk that has only a little butter fat in it. One store has three different jars of low fat milk. One says “1 percent fat” on the jar. The second says “99 percent fat free”, the third says “Low fat” in big letters and “1%”in small letters. As you can see, all the milk has the same amount of fat. The milk is all the same. However, in this store the three jars of milk cost three different amounts of money. Maybe the customers will buy the milk that costs the most.
Most of the food in supermarkets is very pleasing. It all says “Buy me!” to the customers. The expensive meat says “Buy me” as you walk by. The expensive milk jar says “Buy me! I have less fat.”

Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.  

Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses （球场） in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.  

There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.  

Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.
