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.
