It is everyone's duty to help animals to stop extinction (灭绝). As a student, there are so many things you can do yourself too! Please look at the following tips (建议) to help the endangered animals.
Send a letter to your local environment protecting center and show how you feel about the quick extinction of animals. Use the facts to write what you have found. Give some advice to the officers who make the strong rules to save animals.
Draw pictures and make a poster. Put this poster somewhere at school or where people will usually see it. Add some texts in the sign to make it clear why you care about the loss (丧失) of animals. It may encourage people to do something to protect the animals.
Avoid buying things that come from endangered species (物种). When you travel, be careful about what you buy. You shouldn't buy things made from endangered animals or endangered tree species from forests that the animals live on.
Watch your diet. Before eating meals, you should see if you will break a food chain. If you see somebody doing something bad for the food chain, please stop him at once.

The world is in dangerous situation now. We must do something to protect the environment. But, what are the main problems we face?
The greenhouse effect
The atmosphere(大气层)around the Earth is necessary for all living things. It is like the glass of a green house, and it lets sunlight in and keeps heat from getting out. Without it, the Earth would bet he same as the Moon-cold and lifeless.
When we burn fuels such as petrol and coal, we produce a gas called carbon dioxide(CO2). Too much of this gas pollutes the atmosphere, and causes it to keep in too much heat. As a result of the greenhouse effect, the Earth’s temperature is increasing. This causes sea level to rise, and in the future may cause cities to disappear.
Cutting down forests
Every year, we destroy nature by cutting down huge areas of forests. This makes the greenhouse effect worse because trees take in CO2 and produce oxygen. Cutting down trees also destroys the homes of the animals that live in our forests, and causes the surface of the soil to be easily destroyed by rain. This can cause floods and even more damage to the environment.
Bad habits
Many of our habits cause pollution. People often use things once and then throw them away, or leave them on the ground as litter. This creates mountains of rubbish and pollutes our land and seas.
In order to protect the environment, we need to take proper actions. We should be different from many consumers and become “green consumers”. This means that we should only but and use products friendly to the environment. We should also try to recycle as many things as we can. We can reuse things for the same purpose as before, or we can use them for new purposes. If we just learned to live in new and different ways, we can make a difference.
