英語環(huán)保作文：Cars and Air Pollution

　　too many cars have created a lot of serious problems in our world. besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. all the time, they are pumping huge amounts of waste gases into the atmosphere. these gases are very harmful, causing disease and even death.

　　one possible solution is to design and develop clean cars and clean fuels. in shanghai, some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as the petrol. but it may take decades for the new models of clean cars completely replace the traditional ones. another solution is to develop modern public transportation systems and restrict the use of private cars. if the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not buy private cars. and the total number of cars in big cities will reduce greatly.

　　on the whole, the elimination of air pollution needs the collective efforts from the government, the public and the environmentalists.

　　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. ad:from .

　　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

　　earth hour started in australia with millions of homes and businesses turning their lights off for one hour. now it has grown to become one of the world’s biggest climate change initiatives. people are all joining together in a global effort to show that it’s possible to take action on global warming.

　　earth hour has brought about some new changes to our lives. the iconic bird’s nest national stadium and the nearby water cube national aquatics center, usually illuminated by floodlights, went dark at 8:30 p.m., while dozens of hotels, office buildings, shopping malls and restaurants also switched some lights off. people join activities such as candle-lit dinners and star-gazing parties as a response to the call for going dark. however, some critics have dismissed the event as simply a gimmick that will not make any difference.

　　from my point of view, earth hour is a global call to action to every individual, every business and every community. a call to stand up, to take responsibility and to get involved in working towards a sustainable future. earth hour is a message of hope and a message of action. everyone can make a difference.
