We all need a healthy environment.       , we produce waste every day and it         harm to our environment. Though we are young, we can still do    to help. In fact, even the simplest everyday activities can make a real       to the environment. Here are some ideas for you to live a     life.
Remember these three      : reduce, reuse and recycle.
Reduce means “use less”. Don't      things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think if it is really       or maybe the      one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from a         country.
Reuse means “use again”. Use things for       possible. When we buy things, make sure that they       a long time. We should take care of them       they will last, and we should       them if we can instead of throwing them away and buying new ones. Don't use a paper cup or a paper bag. It’s better to use a china cup and a lunch box because you can use them       .
Recycle means “change things into something else”. Although it       energy to change something into something else, it’s better than        things or burning them. Find out       can be recycled in your neighborhood and take part in recycling programs. We should also buy       made from recycled materials, such as recycled paper, to help save     .
