Scientists have learned a lot about the kinds of food people need. They say that there are several kinds of food that people should eat every day. They are: (1) green and yellow vegetables of all kinds; (2) citrus fruits and tomatoes; (3 ) potatoes and other fruits and vegetables; (4) meat of all kinds, fish and eggs; (5) milk and foods made from milk; (6) bread or corn, rice is also in this kind of food; (7 ) butter, or something like butter.

People in different countries and areas eat different kinds of things. Food are cooked and eaten in many different kinds of ways. People in different countries eat at different times of the day. In some places people eat once or twice a day; in other countries people eat three or four times a day. Scientists say that the difference isn't really important. It doesn't matter whether foods are eaten raw or cooked, canned or frozen. It doesn't matter if a person eats dinner at 4 o'clock in the afternoon or at eleven o'clock at night. The important thing is what you eat every day.

Nowadays there are two problems in feeding the large number of people in the earth. The first is to find some way to feed the world's population so that no one is hungry. The second is to make sure that people everywhere have the right kinds of food to make them grow to be strong and healthy.

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 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 of 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 neighborhood and take part in recycling programs. 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.
