1 . As time goes on, people have come to realize the importance of protecting the environment. But they can’t deal with everything by themselves. Take small steps, and you can make a difference.
●Think Green. Think about the environment as you live your life. If you turn off lights and TV when leaving the room, you’ll save energy. If you take shorter showers, you will save water.
●Shop Green. Shopping is fun, but buying things you don’t need is wasteful and even bad for the earth. Before you buy something, ask yourself how much you will use it, and whenever possible, buy things locally made instead of those shipped from far away.
●Dress Green. What really matters is not the colour. It’s how the clothes were made. So look for products made from environmentally friendly(环保的)materials.
●Study Green. What’s better than learning about the environment? Save it while you learn. It can be as simple as using both sides of a piece of paper before you recycle it.

2 . For many of us, summertime means road trips to the beach or mountains, or at the very least some additional dust on the outside of our vehicle. The extra dirt leads us to do one of two things: wash our car in the driveway or head to the car wash. But which choice is better for the environment?
The main concerns with either choice are the amount of fresh water used and the types of chemicals used to get rid of the dirt. Both of these concerns can be closely monitored when washing the car at home, says Katy Gresh, spokeswoman for the Southwest Region of the Pennsylvania Department of Environmental Protection. She advises car owners to keep a set amount of water in a container for the entire wash. “You don’t want to leave the water running or use more than you need for the job,” she says. But even following this piece of advice comes with an environmental risk: Washing your car in the driveway gets the dirty water into drains (下水道).
“Drains are not made for treating waste.” says John Schombert, executive director of 3 Rivers Wet Weather. Even when car owners use natural soaps to wash their car, Schombert says they are probably ineffective in breaking down grease(油脂)anyway.
The commercial car wash knows full well the rules regarding wastewater in drains. According to the International Carwash Association (ICA), professional car washes must use special water treatment systems. These processes not only keep the dirty water out of drains and regular water treatment systems, but also work to reduce water usage at commercial facilities.
As experts point out, cleaning our car at home can use 100 gallons of water. Compare that to self-service car washes, which allow you to use only about 17 or 18 gallons of water. And most full-service car washes average about 30 to 45 gallons of water per vehicle.

3 . 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 choice of sport 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(高尔夫球场) 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 shortages in some local areas.
In fact, 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 pair of good 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 can 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 control your weight better.
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(代替物) 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.
