    How green are you? Do you know how to be green? We all need a healthy environment, but we produce waste every day and it is harmful to our environment. Though we are young, we can still do something to help. Here are some ideas for you.

    Reduce

    Reduce means "use less" .Don't waste things. This saves money and reduces pollution. Before we buy something new, think whether it is really necessary— or maybe the old one is still useful.

    Reuse

    Reuse means "use again" .When we buy things, make sure that they can last a long time. When something is broken, we should repair it instead of throwing it away and buying a new one. Don't use a paper cup or a paper bag. It's better to use a china(瓷) cup and a lunch box because you can use them again.

    Recycle

    Recycle means "change things into something else" .Though it takes energy to change something into something else, it's better than throwing things away or burning them.

    So please remember these three words: reduce, reuse and recycle.
