 Derek Joubert and his wife,Beverly,have made many films about wild animals in Africa. Their films and photographs are very popular and one of the photographs has been on the front cover of a National Geographic magazine.

  A working day for Derek and Beverly starts very early一at 4:30 in the morning!That's when they get up and start filming. And it's a long day―they often work until 8:30 in the evening. In the winter it's very cold and in the summer it can be 40"C. De?rek always does the filming―Beverly never does that,and she doesn't write. But Derek never takes photographs or records the sound. They work very well as a team,and they both believe we should shoot animals with cameras―not with guns!When they have finished filming and taking photographs for the day,they have dinner and Derek usually writes while Beverly looks at her photo?graphs. At night,they usually sleep in a small tent,but they sometimes sleep in the Land Cruiser―when you're very close to wild animals,it's sometimes safer to sleep in the car.

  Derek and Beverly have also traveled around the world and given talks about their work. Derek says that animals are not just something to look at―they play an important role. Beverly thinks the wild ani- mals can teach us a lot about ourselves.

 How green are you? Do you know how to be green? We all need a healthy environment,but we pro?duce waste every day and it does harm to our envi?ronment. Though we are young,we can still do something to help. In fact,even the simplest every?day activities can make a real difference to the envi?ronment. 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 some?thing 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 recy?cled in your neighbourhood and take part in recy?cling programmes. We should also buy products made from recycled materials9 such as recycled paper,to help save trees. So please remember these three words:reduce,reuse and recycle.
