Do you help the environment in any special ways that you would like to share with others Here are some good ideas:
Shopping bags Plastic bags are not good for the environment. Now more and more people begin to use paper bags. And some supermarkets provide recycled (可回收的) paper bags. Here is what you can do:If you don’t buy lots of things,don’t take any bags. This can save millions of bags. Bring a cloth bag when you shop,or use string bags. And you can also reuse your bags.
Clean up our beaches Our oceans (大洋) provide the earth with lots of things. To keep our oceans clean,we have to start with our beaches. Every year on the third weekend of September there is a global(全球的) clean-up,started by the international organization of Clean Up the World. In 1987,around the nation people picked up over 2 million pounds of waste things on our beaches. Next time when you go to the beach,you can take a bag to help pick up litter,or you can join a beach clean-up organization.
Save endangered animals Every day,about 100 elephants are killed by hunters. Hunters kill them because elephants,teeth are worth lots of money. Fishermen have killed over 6. 5 million dolphins. Here is what you can do: Don’t buy endangered animals’ products or boycott (抵制) products from endangered animals.

The world is not only hungry, but it is also thirsty for water. This may seem strange to you, since nearly 70% of the earth's surface (表面) is covered with water. But about 97% of that is sea water, or salt water.
Man can only use the other 3% the fresh water from rivers, lakes, underground, and other sources (源泉). And we can not even use all of that. Even worse, some of it has been made dirty.
However, as things stand today, this fresh water is still enough for us. But our need for water is becoming larger and larger quickly-almost day by day. We should take steps to do with this problem now and in this way we can get away from a serious world-wide water shortage (缺乏) later on.
We all have to learn how to stop wasting (浪费) our valuable water. One of the first steps is to develop (开发) ways of reusing it. Today in most large cities, water is used only once and then sent out into a sewer system(下水道). From there it returns to sea or runs into underground places. But even if every large city reused its water, we still would not have enough. All we'd have to do to make use of sea water in the world is to remove the salt. If we take these we will be in no danger of drying up.
