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.
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
The area of desert in the world is growing every year. Many parts of the world which once had large populations and produced plenty of crops, have become deserts. Dunhuang in China, deep in the heart of the Gebi Desert, was once a great city.
Cattle are one cause of the problem. In good years, famers increase the numbers of their cattle. Then one year, the rains fail to come. The farmers do not want to kill any of their cattle, so the cattle eat ail the grass and anything that grows on poorer land. If this continues for several years, the grass never grows again and the land becomes a desert. One suggested answer is for farmers to limit the numbers of their cattle.
Another problem is that good soil is gradually lost. When trees are cut down, there is nothing to hold the soil in place on the hillside. So when if rains, the soil is washed down the hills and into the rivers. Strong winds can also blow away the valuable soil that lies on the top of the fields.
地球本是多方位,包羅萬象的,但作者從地球的沙漠化方面考慮,列舉了造成此情況的原因,暗示人類要注意這個嚴重的'問題。
這是一篇很好的原因 結果式文章。先陳述結果,後列舉原因。
地球
世界上沙漠的面積每年都在擴大,許多地區曾經人口眾多,五穀豐登,而今卻成了沙漠。中國的敦煌曾經是一個大城市,而現在卻深深陷入戈壁灘的腹地。
造成戈壁灘的原因之一是牲畜問題。年景好時,農民就增加牲畜飼養的頭數。後來有一年天沒有下雨,農民又不想把牲畜殺掉。因此,牲畜就把草和更加貧瘠的土地上所長的任何東西全都吃光。這種情況如果繼續幾年,那麼,草就再也長不出來了,土地也就變成了沙漠。有人提出的解決辦法是讓農民限制飼養牲畜的數量。
另外一個問題就是沃土逐漸流失。樹木被砍伐了,山坡上就沒有什麼東西能夠把土壤保持住了。因此,下雨的時候,土壤從山上被沖刷下來,流到河裏去了。大風也可能把田地表面的肥沃土壤颳走。
