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 also thirsty.This may s 1  strange to you,since nearly 70% of the earth's surface is covered w 2  water. But about 97% of that is sea water,or salt water. Humans can only drink and u 3   the other 3%一the fresh water from rivers,lakes,the underground and o 4  sources. And we cannot even use all of that. Even worse,some of it has been polluted.

    However as things stand today? this fresh water is still e 5   for us. But our need for water is b 6   larger and larger —almost day by day. We should take s 7   to do with this problem now and in this w 8   we can get away from a serious water shortage (^fc^) later on.

    We all have to learn how to s 9   wasting our valuable water. One of the first steps is to develop ways of reusing it. Today in most large cities,water is used only once and then sent into a sewer system (排污系統(tǒng)). From there it r 10   to the sea or runs into underground places.
