Dear friends， I am writing this letter to call on everyone to pay attention to the present disasters caused by human activities. As some of you may know， over the past years， floods， droughts， landslides， and dust storms have frequented our planet. Not long ago， tsunami swept the Southeast Asia， which caused enormous damage. All these have sounded an alarm to human beings. So it is high time that we join efforts to save our planet. Above all， a task of top priority for us is to plant trees as many as possible， especially in the arid areas. At the same time， we should stop deforesting in large amount. And we can save our planet through many other ways， such as saving water and using recycled paper. So don’t hesitate to act out these measures. Even a small action is meaningful to our planet. Please join us in the action of protecting our planet. If you are willing to do something to save our planet， please start from the little thing right around you. Thank you！ Sincerely yours，
Last Sunday my father and I went fishing along a river. We found the water so dirty that we could hardly catch fish in it.
A lot of factories along the river always poured their waste water and rubbish straight into the river which made the river water polluted. In this way most of the fish in the river were killed.
If the river water all over the country is polluted like this， no living things will exist in the water. As we all know， environmental pollution does great harm to living things and human beings. Now more and more people have come to realize how serious this problem is. Our government is doing her best to take measures to fight against pollution. We expect that the water in every river will be made cleaner and cleaner before long.

Dear brothers and sisters,
Oh behalf of the University Students' Union, I, the Chairman of the Union , am earnestly calling for yo ur active participation in our environmental protection campai gn. It is the duty of every global villager; man just can not sustain his glorious c i vilization without a rewarding environment, which will be possible only if man makes considerable efforts to protect the environment.
Do you cherish precio us opportunities to volunteer in our joint efforts in environmental protection? Here is a great one not to be missed by any enthusiastic youth; Right next Saturday, our university is to run a publicity campaign to advocate environmental protection across the city. The University Students' Union will be in charge of recruitment of volunteers. Let's join our h ands and take action immediately.
here are many kinds of animals in the world,but not only the humans.we live in the same world,and we should be friends.as everybody knows,the humans are the rulers of the world today,so we should protect our friends--the animals!
but how to protect them?as first,i think we must stop killing the rare birds and animals,especially the young ones.the second,we have to protect the environment,to make the sky blue,to make the grass green,to give the animals a comfortable space to live
Today, as the development of the technology, people live a much better life than before, the average wage is promoted highly. The economy develops at the cost of polluting the environment, we can see the pollution everywhere, like the river water is dirty, the situation is so serious that we must take some action to control the environmental pollution. First, we should not throw away the rubbish, whenever we have rubbish at hand, we should keep the habit to throw it into the dustbin, sometimes the garbage can be recycled. Second, the government should make some measure to punish the industry which is not deal with the pollution well. With the government’s intervention, the businessmen will pay special attention to the pollution and dare not to ignore it. Protecting the environment needs everyone’s effort, to ourselves and our offspring’s health, we must take action to protect the environment.
Good environment can make people feel happy and fit . To improve the environment means to improve our life.
We should plant more trees and flowers around us . We shouldn’t cut them down . We should stop factories from pouring waste water into the river and waste gas into the air.
Whenever we see litter on the ground , we should pick it up and throw it into dusbins. Never spit in public. Don’t draw on public walls. It’s our duty to protect the environment.
Global warming in the Antarctic glaciers melt faster, sea level will rise rapidly, life on earth will have one's head above water. I told grandpa, this is too much carbon emissions.
When the Spring Festival, we do not have as they often buy a lot of fireworks, fireworks set off once the only in the New Year's eve, can rise to exult beaming atmosphere is ok, otherwise the carbon dioxide is really too much, families, cumulative emissions are impressive.
I appeal through the Internet, the farmers don't in the wheat straw burning, after the autumn harvest of freshwater and sell special corporations to finish molding fuel, can not only generate economic benefits, can save the environmental protection, protect the earth.
But in real life, some people still do not pay much attention, that insignificant, in my opinion, environmental protection from the pieces of small things to start. I have experienced such a small two things: one day, I went to the supermarket to buy things, approaching the supermarket door, saw a few distributed leaflets, see people give, see the car to put, but some people do not, readily I throw the paper in the trash. And see two people with glue will be posted on the wall alone, from afar, like a block of "psoriasis" while they do not pay attention, I took out my unique skills "tear paper", ha ha, "psoriasis" by me Get rid of a large piece. Another time, I play in the floor and found a distant grass on the smoke of smoke white smoke, approached a look, the original is a group of children in our group where the fire burning grass, grass a large, I big brother The identity of the quickly stopped, and talked about the risk of fire and the importance of environmental protection. They are ashamed, quickly from the nearby end of the water to extinguish the fire, the end of the burning action.
We humans all live on a planet, that is the earth. Earth, there is oxygen for us to breathe, as well as dense forests, vast grasslands, boundless oceans, all kinds of animals, constitute a beautiful nature.
But some people do not cherish the earth gave us everything, destruction of nature, a large number of hunting wild animals. Coupled with a variety of damage to the practice of the environment, to our nature brought more and more disasters, long yellow sand instead of the green Linhai, the surging river into a dry river bed, the beautiful scenic area into a wilderness. There are air pollution, the ozone layer has holes and so on these phenomena are people do not protect the environment brought about the consequences. Once upon a time, my hometown air is fresh, the sky is blue, really like a colorful painting, so beautiful! But now, the car it drained the smoke of the smoke, more than the factory, the discharge of sewage, the water into a black odor, causing serious pollution. There was a trash in my hometown, and people put the rubbish here, and some even threw the trash out of the trash. Every summer, here has become a habitat like flies mosquitoes, the wind blowing, hateful white pollution to join in the fun. In the trash next to a pond, the water floating some of the bubble rubbish, water and black and dirty, inside the fish are dead, pond water death in general silence.
I want to loudly call on people: the earth belongs to us human beings, belong to all of us, as long as we use our hands, start from me, from everyone to start to protect the environment, love the natural resources on the earth, so that the pond is still flowing in the clear Home, so that flowers are still so full of flowers in full bloom.
Human, ah, it is time to awaken, and opened his eyes to see our surroundings, this is our home ah, let us wash hands from the gold basin, with their own hands, with their own wisdom, with their own conscience Our children and grandchildren left a harmonious, beautiful home, let us for our generations of life to make an effort to survive it!
With the development of science and technology, the living standard of people is becoming more and more high, the problem of environment is becoming more and more serious, have you found?
Let's say water polluted problem! Gas stations and other factory always put the water into the river without purification treatment, lead to small fish have no home. Our country with fifty-one percent of people are unable to use clean water, the Numbers don't scary? So saving water is imminent, are you still in waste?
We say the trees reduced problem again! We are now a lot of trees are cut down le, so dust storm came, the flood came, and the nature to revenge us. We all know that the use of disposable chopsticks are made from trees, if each of us can use a pair of disposable chopsticks less every day, a year can keep millions of trees, see this, are you still in their own familiar behavior?
We take a look at the sky, blue sky has disappeared, white cloud also hid themselves, it is not the true? No, they just is the smoke from the factory to "protect".
These are the result of the water? Are we human beings themselves, if not disorderly cut down trees, trash, reasonable emission purification of sewage, we believe that our earth will be very beautiful. Everybody is responsible for protecting the earth, let us together to protect the environment!
