WHAT CAN WE DO ABOUT GLOBAL WARMING?

Dear Earth Care,

I am doing a project on behalf of my school about global warming. Sometimes I feel that

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!

Ouyang Guang

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

than you might imagine. This is because no one lives near the top of Mount Kilauea, where the rocks fall. The lava that flows slowly like a wave down the mountain causes far more damage because it buries everything in its path under the molten rock. However, the eruption itself is really exciting to watch and I shall never forget my first sight of one. It was in the second week after I arrived in Hawaii. Having worked hard all day, I went to bed early. I was fast asleep when suddenly my bed began shaking and I heard a strange sound, like a railway train passing my window. Having experienced quite a few earthquakes in Hawaii already, I didn't take much notice. I was about to go back to sleep when suddenly my bedroom became as bright as day. I ran out of the house into the back garden where I could see Mount Kilauea in the distance. There had been an eruption from the side of the mountain and red hot lava was fountaining hundreds of metres into the air. It was an absolutely fantastic sight.

The day after this eruption I was lucky enough to have a much closer look at it. Two other scientists and I were driven up the mountain and dropped as close as possible to the crater that had been formed duing the eruption. Having earlier collected special clothes from the observatory, we put them on before we went any closer. All three of us looked like spacemen. We had white protective suits that covered our whole body, helmets,big boots and special gloves. It was not easy to walk in these suits, but we slowly made our way to the edge of the crater and looked down into the red, boiling centre. The other two climbed down into the crater to collect some lava for later study, but this being my first experience, I stayed at the top and watched them.

Today, I am just as enthusiastic about my job as the day I first started. Having studied volcanoes now for many years, I am still amazed their beauty as well as their potential to cause great damage.
