We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young,we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you. Reduce Reduce means "use less",Don't waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary--or maybe the old 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 abroad. Reuse Reuse means "use again". Use things for as long as possible. When we buy things,make sure that they last a long time. We should look after them so that they will last, and we should repair 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 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. Find out what can be recycled in your neighbourhood and take part in recycling programmes. We should also buy products made from recycled materials,such as recycled paper, to help save trees. So please remember these three words:reduce, reuse and recycle. Question: What is the passage about? Options: A: How to produce things. B: How to burn things. C: How to help others.
