Environmental protection theme composition 1 The earth we live in suffers from disasters every year: floods, droughts, mudslides, locusts and plagues. Then why is there a disaster? Ah, the original culprit is human. Humans cut down a large number of trees, making a large area of forests disappear immediately. Without the protection of the forest, the flood washed away the houses and killed many people and animals. Coupled with people littering and destroying the natural environment, various disasters occur every year.
Some time ago, the drought continued, and it was difficult for people and animals to drink water in five southwestern provinces; Now there is a flood in the upper reaches of the Yangtze River, and the rushing flood has nowhere to go, so it attacks the city and plunders the land. On the surface, it must be because of climate change, but we can't ignore the root cause of human felling trees. Taking this flood as an example, the vegetation in the middle and upper reaches of the Yangtze River has lost its interception function because of its destruction. Yunnan cut down tropical forests to plant rubber and transgenic eucalyptus, and Yamakaji, Hubei planted pulp forests. Due to the high mountain, steep slope, poor soil erosion resistance and heavy rainfall, the ecosystem in southwest mountainous areas is very fragile. Once the natural vegetation is destroyed, ordinary heavy rain may cause floods.
China has built 22,000 dams, accounting for 45% of the total number of dams in the world. Judging from the frequent occurrence of droughts, human beings' endless "changing rivers to build reservoirs" may be the main cause of floods and droughts in the Yangtze River.
Hubei is known as "the province of thousands of lakes". In 1950s, there were 1332 lakes over 100 mu in Hubei, including 322 lakes over 5000 mu. However, due to "reclaiming land from lakes" and intercepting water in the upper reaches, several decades later, 15 lakes with an area exceeding 100 mu disappeared in Hubei every year.
Of course, it is precisely because human beings wantonly destroy the environment and nature that the environment of the earth, the hometown of human beings, has become very bad.
We should start from small things, start from life and do our best to protect the environment. The method is as follows: "Save every piece of paper and every drop of water, wash your hands in the toilet, mop the floor and wash your clothes, wash your hands with a mat, wash your face with water in the toilet, use less paper when going to the toilet, turn off the lights when going out at night, and don't take an electric car when going out to save energy. Because cars and motorcycles will emit exhaust gas, which will pollute the air, thus causing the increase of carbon dioxide and destroying the environment. We should also save every kilowatt hour, turn on less air conditioners and blow more electric fans, because electric fans save electricity. I saw some people selling frogs and snakes in the market. I don't think those people protect animals. Frogs eat all kinds of pests, while snakes eat mice. If there are only humans and no animals (including frogs and snakes), the end of the earth will come. In order to protect our environment, we should plant more trees and stop cutting down trees. If anyone catches a frog or a snake, we should stop it at once.
The new semester has begun, and I am about to become a fourth-grade student. In order to protect our environment, I will also make my contribution. Cutting down trees causes soil erosion, chemical plants discharge sewage and pollute water resources, and the chimneys of factories smoke every day, including the tail gas emitted by cars. These things are beyond my control, but what I can do is: don't trample on the lawn, don't pick flowers and trees, and don't throw garbage into rivers, ponds, streams, etc. Don't catch beneficial insects and animals, and don't defecate everywhere. ...
The environment is protected by everyone, and I can't do it alone. Partners, let's work together to defend our homeland and build a beautiful global village!
Essay 2 on the theme of environmental protection recently went swimming in East Lake, and found that the water quality was not good, the color of the water was dark, and occasionally it smelled strange smell. There are three main reasons:
First, improper urban sewage treatment, due to rain, urban sewage discharge is not smooth, resulting in sewage reflux, so that Xiaoling River is polluted;
Second, the problem of industrial sewage discharge along the Daughter River has not been effectively solved, which makes the water quality problem of the East Lake where Daughter River meets Xiaoling River more serious;
Thirdly, the plants in East Lake have not been treated, which makes a large number of aquatic plants rot and float in the lake, and the water quality is polluted.
Associated with the water pollution in East Lake, the earth on which we live is also suffering from various kinds of pollution. Therefore, people emphasize low carbon and attach importance to environmental protection. The purpose is to remind people that we must really love our home, love its green mountains and green waters, love its green grass and blue sky, and never allow pollution to the natural environment.
Once upon a time, people hacked and hacked, destroying the ecological balance of nature. Dunes have swallowed up thousands of hectares of fertile land, floods have destroyed lovely homes, sandstorms have swept half the country, and nature's revenge has embarrassed mankind. Everyone knows that without the earth, there would be no human beings; Without a good natural environment, there is no good life. Blindly plundering and conquering nature for a certain benefit will only destroy the ecosystem and bring mankind to the brink of difficulties. The flood in 1998 and the sandstorm in 2000 are both warnings issued by nature to human beings, which should arouse the attention of all mankind to environmental protection.
Protecting the environment is everyone's responsibility. Take care of the environment, starting with me. It is necessary to develop good health habits, actively participate in environmental protection activities, and consciously protect the environment, so that flowers are fragrant, forests are lush and lakes are clear!
Essay with the theme of environmental protection 3 Every year around the vernal equinox of the lunar calendar, it is a time of strong winds and sandstorms. However, although there are strong winds in Tianshui in recent years, there are few sandstorms and the air is fresh and sweet. Why is this? It turned out that the standing "greenguard" blocked the sandstorm for us.
As we all know, trees can expel oxygen and resist wind and sand. But no one consciously planted trees before. But cut down the trees one by one to make all kinds of tools and furniture, and decorate the home beautifully. But they don't know that these behaviors have hurt themselves and destroyed their homes. People in many areas cut down trees indiscriminately, causing natural disasters such as sandstorms, floods and El Nino. In recent years, in order not to make these natural disasters continue to spread, Tianshui people consciously shouldered shovels and pickaxes to plant trees on the mountains, planted a large number of green trees on the bare land, and built a "windbreak wall" for Tianshui. Visitors to Tianshui see Qingshan Bao and say, "This is not like the Loess Plateau. It is clearly a small Jiangnan with green mountains and green waters! "
Although the greening on the mountain is good, the city has become beautiful and tidy. However, people's actions and awareness of protecting the environment are still very poor. Black smoke from factories in cities pollutes the atmosphere and air; People discharge sewage into the river at will, making the original crystal clear river dirty and smelly; Farmers who grow vegetables in Heba use this water to "water" vegetables and take them to the market for sale. Isn't this for us to drink sewer water?
The "river-crossing customs line" under construction has improved the pollution of rivers, but also dug up some flowers and trees. I want to say to the workers' uncles, "You can't dig these flowers and plants for nothing to repair the river. You can kill two birds with one stone while digging! "
A few years ago, a new pedestrian street was built in Tianshui. There are many antique buildings in the street. Each antique building has two or three floors, and there is a beautifully carved faucet in every corner of the roof, which is magnificent. The street surface of the pedestrian street is composed of granite carefully selected by craftsmen. There are several ancient pagodas in the street, two of which have fallen leaves. Managers wrapped rattan leaves made of plastic around the trunks of the two ancient pagodas, and then installed green spotlights from the trees. Whenever night falls, the pagodas with green lighting look like real ones. They look much younger.
There are many benches on the pedestrian street for people to enjoy the cool and rest, but they can't enjoy these benefits! Someone deliberately stood on it and stamped their feet, and the stool was "green" and "purple". The sound of "squeaking" kept coming, as if to say "It hurts! It hurts! "
The shell boxes on the pedestrian street are very beautiful, and each one looks like a small house. They open their mouths wide, waiting for people to feed them. But some uncivilized people pour bad milk into shell boxes; Some even opened the lid under the shell box to let the smelly garbage leak into the street, making the street stink.
There are two lawns surrounded by iron railings in front of Tianshui Hotel. There is a wooden sign on the lawn, which reads in ten red letters: "The grass smiles shyly, please don't disturb". Let's take care of the lawn and don't trample it. However, some children deliberately shoot at the lawn, play football or throw stones, beating the grass that had been held high and bent down, twisting it into a ball like a hemp blanket.
On Sunday, my mother took me to the pedestrian street to buy clothes. I saw a child throw a bottle into the shell box as a basketball, and the result was thrown outside. The child ignored it and was about to leave. I hurried to pick up the bottle and put it in the shell box. Passers-by said I was a good boy to protect the environment, and the child bowed his head in shame. I guess he will never litter again!
I hope everyone can get rid of the bad habit of not paying attention to hygiene, protect our unique nature and make our city more beautiful.
Notes after writing: The antique pedestrian street in Tianshui is beautiful, but some people don't know how to take care of it. Tianshui has a mild climate, but we still need to plant grass and trees. I hope that through this activity, people will feel that protecting the environment is everyone's responsibility.
Parents' words: Great changes have taken place in our hometown through the construction in recent years. It is urgent to protect the environment; Protect the environment and start from a young age.
Teacher's comment: Meng Qingyao's exercise "Environmental Protection and Pollution" shows everyone his personalized thinking from the unique perspective of primary school students. Indeed, in recent years, Tianshui people have made great efforts to carry out the greening construction of the north and south mountains, built a "windbreak wall" for Tianshui, and built a "river-crossing customs line"-Tianshui Lake, so that Tianshui people can live in the "small northwest country" with "green mountains and green waters".
People should be more beautiful because of the beauty of mountains and water, and everyone should cherish and protect the home where we live. Between the lines, the little author reveals his dissatisfaction with some people with poor environmental awareness: air pollution, sewage discharge, and the benches on the pedestrian street being trampled "black and blue" ... This really makes people feel that the little author is worried about environmental protection. The proposal of "planting while digging" mentioned in this paper is simple, but it expresses a fourth-grade pupil's love for his hometown and his strong desire for people to protect the environment.
Environmental protection theme composition 4: protect the environment, starting from me. As we all know, the earth is our home, and the environment is closely related to our life. Humans have consumed a lot of water resources, polluted the environment and destroyed a beautiful earth. There is less and less water, and animals and plants are on the verge of extinction ... all because we don't pay attention to protecting the environment. Some people cut down trees everywhere, and now the world cuts down 1 1 10,000 hectares of forest every year on average. What a big number! Some people throw rubbish at will. Garbage floats on the stinking river, plastic bags are hung on the dirty branches, and peel scraps are piled up on the dark grass. The environment has been greatly damaged, and clear rivers, green forests and blue skies have all disappeared without a trace.
I read a cartoon in a book: in a big forest, a man was cutting down a tree with a cigarette in his mouth and a sharp axe, and the tree was crying. There is a woodpecker on that man's shoulder. The woodpecker looked at the man's head and said, "There must be insects in this piece of wood." That man does have a "bug" in his head. This "bug" refers to the human bug that destroys the environment. Strangely, the woodpecker said he had a "bug" in his head. However, in our daily life, in this world, there are countless people with such "worms in their heads", but few woodpeckers. Usually, many students' draft papers are thrown into the trash can after only a few strokes. You know, these papers are just trees. The water is too boiling when you wash your hands, not to mention. After washing your hands, you left the tap on. Let the water flow. You should know how precious water is in arid areas. Usually, throwing garbage on the ground will not only affect the environment, but also affect the beauty ... You know, our earth has been greatly damaged now, and those who have "worms in their heads" have never woken up. They destroy the environment for their own benefit: cutting down trees and destroying plants; For convenience, sewage is discharged into rivers. I don't know how many rivers are undrinkable. Our mother river, the Yellow River, has become turbid. The former land of abundance and the beautiful scenery of Beijing no longer exist, the air pollution is getting more and more serious, and acid rain is almost everywhere ... In the face of such shocking things, people don't seem to wake up, the greed bug in people's minds is getting bigger and bigger, and people have been fascinated by desire.
Now we must protect our beautiful earth, because saving the earth means saving the future. The first thing we should do is to kill the greedy bugs in our minds. Students, please light up your inner mirror. "Is there any bug in your mind?"
As a primary school student and a small citizen, we should take active actions, starting from small things, starting from the side and starting from me. Develop good hygiene habits, don't litter, don't dump garbage, bend over to pick it up when you see garbage, and don't spit everywhere; Take good care of flowers and trees and keep the campus environment clean and tidy; Protect wild animals, stop cutting down trees and protect plants; Be a little guardian to protect the environment.
I believe that through our joint efforts, Mother Earth will regain its former glory in the near future! Give us a clean and beautiful home!
The essay 5 on the theme of environmental protection is familiar to everyone. Low-carbon environmental protection is no small matter, low-carbon environmental protection has no distance. "Low-carbon life, start with me" is my slogan and my action!
Say "No" to "Water King"
Mom used to be the "king of water consumption" in our family. When washing vegetables and dishes, she always leaves the water pipe open, allowing tap water to flow freely. Once, I heard the sound of running water from the kitchen in the living room. I ran to the kitchen at the door and found my mother washing vegetables with the tap on, and there was a pile of unwashed potatoes next to her. I ran to turn off the tap and said to my mother, "Mom, is water the source of life?" Zhang Er's mother looked at me puzzled and asked, "Yes, why?" "Then why do you waste water? Washed with a washbasin, wouldn't it save trouble? " My mother paused for a moment, and then said to me shyly, "Oh, I really didn't pay attention to this." You reminded me right! " Since then, the phenomenon of "wasting water" has changed greatly. Although it will be repeated occasionally, as long as it is reminded, it will be changed immediately.
Call "Stop" to "Electric Tiger"
Our family used to have an "electric tiger" that consumed electricity without blinking an eye, and that was my father. Because my father often writes materials on the computer, I often find that the computer is not related, and I don't know whether my father left it on intentionally or forgot to turn it off to save trouble. Once it was time for dinner, my mother brought the food to the table. I called him several times, but he seemed to turn a deaf ear to what happened outside the window. I think Liu Bei invited Zhuge Liang out of the cottage. I invited you several times and still didn't come. It was too ostentatious, so I ran to him and said loudly, "Dad, it's time to eat." He just stood up to eat. I saw that my father had no intention of talking about mobile phones at all, so I asked him, "Dad, do you want to save electricity, low carbon and environmental protection?" "Of course." Dad replied smoothly. "Then turn off the computer to eat before turning it on, so you can save some electricity!" I warned you. Hearing this, my father sat down thoughtfully and turned off the computer. Then call me a "little housekeeper".
It is under my constant reminding and urging that my "water-wasting king" and "electric tiger" are only in name only, and have already entered the advanced ranks of low-carbon environmental protection in our family.
