Nowadays, a variety of environmental problems affect our entire world. But now that most important thing for our life is being polluted. A clean environment is necessary for a peaceful and healthy life. When fossil fuels i.e. oil, coal and gas are burned to provide energy for cooking, lighting etc. they form polluting gases. In the sea, oils spills pollute sea water and kill marine life. Artificial fertilisers pollute river water, killing wildlife and spreading disease. Pollution could be prevented by: Keep clean environment ; Use recycled paper to help save trees ; Plant more trees ; Try to avoid buying plas ; To protect environment we also have to save energy ; Walk more, drive less  ; to protect natural resources ; to conserver wild life ; to conserve the old forest, rainforest, to prohibit hunters who hunt wild animals out of the law .When we protect the environment, it’s mean we are protecting ourselves and our future as well. I hope that in the future the earth will be cleaner.

Environment is an essential part of our life. A clean environment is necessary for a peaceful and healthy life. An environment is the natural surroundings which helps human beings, animals and other living things to grow and develop naturally. But nowadays, our environment is disturbing many diffrent ways. Any type of disturbance in the nature's balance affects the environment totally. It does not onlyruin human lives but also affects the environment with the lttle step taken by everyone on the earth. We should reduce the amount of waste, throwing wates preperly to its place only... and many other simple ways. It on very inportant to save envirnment  for human existeence.When we protect the envinment, we are protecting our selves and our future as well

          Every years in my school , there are many volunteer works . And I always join it . First , I don't understand that : '' What is the volunteer work ? '' . But when a volunteer explains , I understood . Then I donate many things such as : pens , books , shoes , clothes , ...... I think it is very useful for many people need them . I love doing volunteer works very much , because I can help people poor , ..........

Decide which of these things may not be possible in big families:

- being by yourself

- playing sport with others

- helping younger children

- living in a big house or flat

- keeping the place tidy

- having a low supermarket bill

- doing lots of washing

- travelling cheaply

- annoying your older brothers and sisters
