individuals can have little effect on such huge environmental problems. However, 1 still think people should advocate improvements in the way we use energy today. As I'm not sure where to start with my project, I would appreciate any suggestions you may have.

Thank you!

Dear Ouyang Guang,

There are many people who have a commitment like yours, but they do not believe they have the power to do anything to improve our environment. That is not true. Together, individuals can make a difference. We do not have to put up with pollution.

The growth of the greenhouse gas, carbon dioxide in the air actually comes as a result of many things we do every day. Here are a few suggestions on how to reduce it. They should get you started with your project.

1 We use a lot of energy in our houses. It is OK to leave an electrical appliance on so long as you are using it - if not, turn it off! Do not be casual about this. So if you are not using the lights, the TV, the computer, and so on, turn them off. If you are cold, put on more clothes instead of turning up the heat.

2 Motor vehicles use a lot of energy- so walk or ride a bike if you can.

3 Recycle cans, bottles, plastic bags and newspapers if circumstances allow you to. It takes a lot of energy to make things from new materials, so, if you can, buy things made from recycled materials.

4 Get your parents to buy things that are economical with energy - this includes cars as well as smaller things like fridges and microwaves.

5 Plant trees in your garden or your school yard, as they absorb carbon dioxide from the air and refresh your spirit when you look at them.

6 Finally and most importantly, be an educator. Talk with your family and friends about global warming and tell them what you have learned.

Remember - your contribution counts!

AN EXCITING JOB

I have the greatest job in the world. I travel to unusual places and work alongside people from all over the world. Sometimes working outdoors, sometimes in an office, sometimes using scientific equipment and sometimes meeting local people and tourists, I am never bored. Although my job is occasionally dangerous, I don't mind because danger excites me and makes me feel alive. However, the most important thing about my job is that I help protect ordinary people from one of the most powerful forces n earth-the volcano.

I was appointed as volcanologist information for a database about Mount Kilauea, which is one of the most active volcanoes in Hawaii. Having collected and evaluated the information, I help other scientists to predict where lava from the volcano will flow next and how fast. Our work has saved man lives because people in the path of the lava can be warned to leave their houses. Unfortunately, we cannot move their homes out of the way, and many houses have been covered with lava or burned to the ground.

When boiling rock erupts from a volcano and crashes back to earth, it causes less damage
