Dear teachers and students,
Hello! Today, my topic is "protecting the environment and everyone is responsible".
Throughout the ages, earths mother has nurtured countless generations of children with sweet milk. She was beautifully decorated by her children. Now, however, the human race tormented her for its own sake. Man has only one earth; And the earth is facing a severe environmental crisis. "Save the earth" has become the most powerful voice of people all over the world.
Students, we are the small masters of the earth, environmental awareness is the important symbol of modern people. We should establish a sense of responsibility in The Times. Focus on the world and focus on the campus. To pick up the scraps of paper with a bent waist; Dont throw about; Take a few more steps, dont pass through the green belt, trampling green space. "It is incumbent on all of us to save resources and protect the environment. We need to start from now, start from our side, start small. Through our efforts, the sky of the motherland is bluer, the land is greener, the water is clearer. Whether it is the past, present, or future, whether it is family, country, or the world, the environment is always our friend, to be kind to our friends, to be kind to ourselves.
"There is only one earth", let us protect our homeland together.
Environmental problems are as big as not for individual country or individual people to address. In other word， we have reached the stage that environmental problems be solved for international view. To what extent do you agree or disagree?
In recent years， many nations have bee more aware of the environmental issues each nation faces， such as air and water pollution. The question is， are the environmental issues a national problem or an international problem? It is my belief that the environmental issues have grown to the point of being an international problem needing international cooperation to resolve.
Because of the differences in environmental policies， resources and technology， international cooperation could provide quicker results and have a greater impact on bringing resolution to environmental problems for nations of differing environmental policies and of lesser resources and technology. By pooling international resources and technology to address the environmental problems， the disadvantaged nations are provided the assistance needed. Otherwise their environmental conditions deteriorate ultimately affecting the resources and environment of the world as a whole.
One of the difficulities to an international resolution to environmental issues is the difference in individual nations view and policies toward environmental protection. In order for international cooperation to occur and succeed， the nations of the world must submit themselved to international standards and supervision by an international mission elected by the participating nations of the world. All members must agree to abide by the standards established.
The environmental issues facing each country are not unrelated to the well being of the rest of the world. The impact is long term and international in scope. Without international cooperation and agreement to address such environmental issues as glacial melting at the South Pole， depletion of the ozone layer， water pollution， air polution， etc.， the environmental conditions of the world will deteriorate to the detriment of every nation， not just those that ignore or lack the resources and technology to resolve their individual environmental problems.
As part of the same planet， it is the responsibility of each individual and nation to protect the global environment. Only international cooperation will provide the timely solutions and the effectiveness needed to stop the deteriorating global environment.
As we all know， the environment around us is getting worse and worse /more and more seriously today. Water is polluted， we have no clean water to drink. Many trees are cutting down， some animals are getting less and less. Some factories are pouring dirty air into the sky. The population is increasing faster and faster， resources are getting less and less…etc. Not only does it affect our lives and health， it also has a great affection in the future. People’s health has been greatly affected by air， noise and water pollution. Many people died of diseases. In order to live a better life， something must be done to stop the pollution. It’s our duty to protect our environment. We shouldn’t throw away rubbish everywhere. Trees are very helpful and important for us. We should plant more and more trees in order to live better and more healthy in the future.
If everyone makes contribution to protecting the environment， the world will bee much more beautiful. In a word， if everyone pays more attention to our environment， there will be less pollution and our life will be better. “There is only one earth”， I hope everyone will protect our environment well.
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 themselves.
Stepping into the new century environment pollution has become more serious than ever since. There are different kinds of pollution. Such as water pollution air pollution and noise pollution and so on. It seems that we live on a planet which is full of pollution. where all these pollution comesfrom? To a large extendthe environmental destruction is the heavy price that we pay for the rapid development of economy and the growing population. In order to have more fuel people cut down trees and dig more corals. But the growing needs for energy are hardly to meet.
Countless private cars on the street the gas stations are short of gasoline even the government has raise the price so many times in order to control the needs of gasoline but it’s still not working. Overusing the natural resources has already affected the ecological balance. However the factories still release the toxic air into the sky and the polluted water into the rivers. People still lack of the conscious of protecting the environment. I think it’s time for all of us to do something.
The government should put forward some more strict laws to prevent the environmentfrombeing further polluted. And they should let people know more about the importance of environment protection. And we should find the balance between the economic growth and environmental protection. Plant more trees in the deserts and stop cutting down the forest. Forbid the factories to pour the waste water into the rivers directly. Encourage people to use public transportations to work. Both government and ordinary people should join hands together to make our home clean and fresh again.
Only in this way our earth could be a better place to live in.
