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 make it clear that your choice of sports 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 kinds of chemicals and a great deal of energy are used to keep its fields
in good condition. This causes environmental problems. For example, in the dry areas of Portugal and Spain,
golf is often the cause of serious water shortage in some places.

resources (資源) and you purse. Simple and free, power walking can also keep you fit. If you walk very
often, it will be good for your heart and bones. Experts (專家) say that 20 minutes of power walking daily
can make you feel less nervous, 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 (再生材料). But the final purpose should be "green gyms". Compared

membership. And best of all, it's free.
