     Want to save the environment? You probably can't fix everything on your own, but by taking small steps

and keeping the environment in mind every day, you can make a difference,

     1. Think Green. Challenge yourself to think about the environment as you live your life. If you shut off

lights when you leave the room, turn off your TV when you're not watching it, you'll save energy. If you take

shorter showers, you'll save water.

     2. Shop Green. Shopping is fun, but buying things you don't need is wasteful and bad for the earth. Before

you buy something, ask yourself how much you'll really use it. Keep yourself away from buying products with

unnecessary packaging (包装), and whenever possible, buy things that were locally made instead of those

shipped from far away.

     3. Dress Green. Wear green trousers and T-shirts if you want. But what really matters isn't the colour, it's

how the clothes were made. If you want to help the environment, the best place to find clothes is at a vintage

store, but you might not want to buy everything used. No matter where you shop, keep an eye out for products

made from environmentally friendly materials like organic (有机的) cotton, which is grown without the use of

pesticides (杀虫剂).

     4. 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, or reusing an old textbook:instead of buying

a new one. If you want to do more, join an environmental group at your school, and encourage your friends to

join, too.
