Now I want to talk about a beatiful world! When I was young,I always dreamed that I lived in a beautiful country. There were many flowers and trees around our city.We counld hear the birds singing and see the children dancing. The streets were clear and the the air was very fresh! How nice it was!But that only was a dream of mine!How I wish that it would be come true! So I think we should do something to protect our environment. Everyone should make a contribution to protect the environment. Taking care of our environment is very important.Where ever you live,you can do something around your neighbourhood. Have you ever thrown any litter onto the ground?Have you ever drawn pictures on public walls? Have you ever cut down trees?If your answers are "No",it means that you have already helped protect our environment. It is our duty to keep our envionment clean and tidy. You might ask yourself,"Have I ever picked up some rubbish and thrown it into a box?Have I ever collected waste paper or bottles for recycling?Have I ever planted any trees or flowers in or near my neighbourhood?"If your answers are"Yes",it means that you have already done something useful to improve the environment. Now I want to say :Let`s do our best to make our world more beautiful

It is important to protect our environment, the energy in the world is limited. turn off the light and other appliance when you ,re not using them, we'd better not waste the energy, use public transportation, recycle the waste，I can learn more to develop new and clear energy, like the energy from the wind and solar 等。 参考例文：     With the development of our society, energy in the world becomes more and more limited, so it is quite important for us to save energy and to protect our environment. As a student, there are a lot of methods we can do to save energy at home. For example, first, we can turn off the light as well as other appliances when we are not using them. Second, recycle the waste water, paper and other waste so that we can reuse them. What's more, it is suggested to use public transportation more instead of private cars.      Above all, everyone can make a great contribution to our environment. I hope I can learn more to develop new and clear energy, like energy from the wind and solar.
 There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.

To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.
In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themsel
