Teachers, students, Hello, everybody!
Each of us has a family, also love their home, but you know we have a common house? - That is our planet! Earth is our common "home", and is a very beautiful home, then there is blue sky with white clouds, a tree with red flowers, birds contention, how beautiful all the ah, but that we have not thought about how to protect the earth ? October 15, 20xx astronaut Yang Liwei and the family telephone said excitedly, "I - see our beautiful home", which sounds from space, how many Chinese people moved, the number of foreigners Yeah.
Today, however, when we again face the "beauty of our home", we can also say? Blue sky, how life used to be a brilliant landscape, now trapped in the gray, the clean air become very close to a desire to dream. Faced with an increasingly serious air pollution, looking at the sky, you say? Know of a small village called Demonstration of field do? The place was surrounded by the Castle Peak, Green River Flows, a beautiful place ah! However, the villagers are aware of the environment, no one important, they are deforestation, land reclamation, deforestation, forest gradually disappeared, the stream gradually dry, well water gradually withered. Today, this no longer see the mountains and never see green water, and the village people use very little water, wash your face, then keep feet, and finally carefully pour the water in a vat .... .. keep pouring in ah ....... This is a natural right to their punishment, which is the earth for their ambitions ah!
Students is only one earth. Earth is our lovely "home"! Let us join hands, for our home planet to create a better tomorrow.
Hello everyone,I'm ×××.My topic is "we should protect earth". As we all notice,the weather becomes very odd recently.In a month like now,it should be quite warm,but I'm still wearing my winter dresses.It's still rather cold,which shouldn't happen at this season.In summer it's extremely cold while terribly hot in winter.All these factors make earth a unfavourible place to live in. here you can show some pictures or other materials you have collected. We all know that earth is our common mother.We all live in it.She provides us everyting we need.She has been enormously generous to us.We should do our best to care for her. Now before it's too late,I think we should start to take actions.Protect the earth starting from you and me,from what we can do ourselves.For instance,ALWAYS throw rubbish in the bin and etc. Besides,we should try our best to know more about environment protection knowledge.The bad weather has made us suffer a lot.I believe everyone here has the same feeling as mine.I guess that's the price we paid for doing harm to the earth.We have nobody but ourselves to blame for that. At last,have you seen the movie"the day after tommorrow".It's a movie about weather.It's a good one and worth to have a look. THANK YOU!
Shanghai residents breathed the most polluted air they had seen in two months on Wednesday as weak cold air from the north brought pollutants to the Yangtze River Delta.
But clean air is expected on Thursday thanks to another round of cold air, forecasters said.
Seasonal factors played an important role as winter is the high pollution season, and straw burning in nearby provinces also contributed to the pollution, experts said.
Shanghai's air quality index, a new air quality reporting system that monitors sulfur dioxide, nitrogen dioxide, carbon monoxide, ozone, PM10 and PM2.5, reached 254 by 7 pm on Wednesday.
The figure, which indicated the air had reached the level of heavy pollution, was the highest seen since the index was introduced two months ago, according to the Shanghai Environmental Monitoring Center.
Shanghai's hourly density of PM2.5, air particles smaller than 2.5 microns, also reached 250 micrograms per cubic meter by 10 am, while the reading was only 60 micrograms per cubic meter early Tuesday morning.
The heavy pollution in the eastern metropolis followed thick air pollution in Beijing over the weekend. Beijing's density of PM2.5 broke the record since the municipality began publishing the data in early 20xx as its figure went higher than 900 micrograms per cubic meter in several districts of the city on Saturday.
Lin Chenyan, a forecaster with Shanghai Environmental Monitoring Center, said the cold front brought in airborne pollutants from the north.
"The cold snap is like a broom sweeping down all the way to Shanghai, and it brings the dust here," said Lin, adding that atmospheric motion sometimes causes trouble such as that.
Before arriving in Shanghai, the pollutants had left some of Shanghai's neighboring provinces shrouded in smog and fog.
Fifty out of the 72 monitoring stations in Jiangsu province reported medium to heavy pollution on Monday evening, according to Zhang Xiangzhi, deputy director of the Jiangsu Environmental Monitoring Center.
Yang Xin, a professor with Fudan University's department of environmental science and engineering who specializes in atmospheric particulates, said seasonal influences explain the record-breaking data in both Beijing and Shanghai.
"Take Shanghai as an example. It just celebrated its cleanest summer in 20xx - sea breeze from the southeast is helpful in diluting pollutants in the air. However, the monsoons coming from the northwest in the winter usually bring dirty air from the north," Yang said.
Agricultural straw burning in nearby areas also contributed to part of Shanghai's PM2.5 reading, according to Wang Lin, a researcher at Fudan University's Department of Environmental Science and Engineering.
"But it's hard for the Shanghai government to prohibit farmers in the neighboring regions from doing so," Wang said.
According to Lin, the forecaster, Shanghai's air was set to improve on Wednesday night and early Thursday morning. The next wave of cold air is much cleaner because of the clearing of air pollution in the north.
