Just say the river on the west side of my home! In the past, the river was crystal clear and sparkling. There are many small fish and shrimps singing and dancing in it, swimming freely, living a carefree life all day, and the river is full of vitality. I liked to play there at that time.
Nowadays, because paper mills and other construction sites in big cities discharge sewage at will, people keep littering. The vibrant river disappeared and became a smelly river without fish and shrimp. I don't like it anymore!
Human beings depend on the environment for survival, and the environment depends on human protection. Do humans have to wait until the moment when the earth is destroyed to realize it?
I appeal: it is urgent to protect the environment! Let's act together.
Environmental protection: an English composition about writing a letter to the mayor to protect the environment
Recently, the problem of environmental pollution has become more and more serious.
Air pollution, noise pollution and water pollution are all seen in the newspaper.
It's everywhere. Obviously, we should do something to protect our earth. because
We only have one home. We should try our best not to pollute the environment.
Call on people around us to work hard to protect our unique home.
Protecting the environment, protecting the environment, protecting the environment is everyone's responsibility! Start with me! There are more and more people on the earth, so human beings must protect the environment better. In this way, people can live on the earth for a long time. However, with the increasing number of various factories, pollution has followed, and the pollution and waste gas discharged by factories are more harmful to human beings and the environment. But some factory owners, for their own black-hearted money, ignore the health of others, which is really hateful! Some people eat lunch boxes and throw rubbish after eating them. There are also random cuts. Please, all these people with shortcomings must get rid of this immoral bad habit! Therefore, we should loudly appeal to everyone in the world to start from small things, from me and from now on! Everyone should strictly and boldly supervise, seize heavy penalties, and never be soft! Especially the factory owner! Protecting the environment is everyone's responsibility! In this way, the environment can slowly change back to clean air without pollution and everywhere. There are several colors of stones at the bottom of the river, which can be seen at a glance. You can see beautiful scenery, flowers and trees everywhere! Ah! People can go back to the beautiful and pollution-free nature. Class 3 (5), Grade 3, Gong Ming No.1 Primary School
Environmental protection composition 150 words protect the environment
On campus, we can learn a wealth of knowledge, meet serious and responsible teachers and find like-minded partners. School is my home. On campus, garbage can be seen everywhere on the roadside. Bend down and pick it up with both hands and throw it into the dustbin. This small action will reduce pollution and add cleanliness to the campus. When the surrounding environment is clean and tidy. Are we too hard to be happy? Let's start from now on, start from me, start from scratch and add a clean home.
The answer is difficult! Please adopt!
Environmental protection composition 150 Among the fragrant flowers in the four fields, the flowers are smiling, and butterflies are flying with bees and chasing each other. In the abrupt forest, some birds sing charming songs, some dance beautifully together, and some play games happily. How beautiful that tree is with its long hair!
But now, people chop down trees and burn firewood to make disposable chopsticks, which destroys the ecological balance of nature. When the flood comes, we will die without resistance. Sandstorms never let people leave alive. In fact, these are all warnings from nature. And people don't listen to advice and continue to do these things that destroy nature. People indiscriminately catch birds and other rare wild animals, make them extinct, even send them to restaurants, and then sell them for a little money. People catch and kill indiscriminately, but help pests, let them destroy the forest, and finally harm themselves. People waste a lot of water resources, for example, they run out of water without turning off the tap, and the water falls down after a few sips. If every household has a little water, isn't the whole water resource more? Factories make things and put in some chemical formulas. When pollutants are discharged, the air is polluted more seriously, causing the air to smell bad, and flowers and trees bow their heads in despair. It has brought many terrible viruses to people, affected people's health and destroyed the ecological environment.
Therefore, we should take action, don't litter, save water, don't cut down trees casually, care for animals and other small life, and use less chemical formulas in factories, which will do less harm to nature and give people a good environment. .
I believe that if we do this, our environment will be good, people will live well and live longer, so the world will become a beautiful world.
There is only one earth in the sentence category of 1000 words or famous sayings about environmental protection.
The earth is our home, respecting the earth means respecting life, saving the earth means saving the future, and protecting ecological balance means protecting human beings.
The rapid development of science and technology at an unprecedented speed and scale has enhanced the ability of human beings to transform nature and brought unprecedented prosperity to human society. However, long-term plundering of resources will be punished by nature. We have encountered environmental pollution such as air pollution, white pollution, water pollution, air pollution, decoration pollution, soil pollution, light pollution and the ecological crisis of the earth. For example, the ozone in the atmosphere is decreasing, the global temperature is rising, the tropical rain forest is decreasing sharply ... The sharp decline of the quality of the earth's environment has become a worldwide problem that directly threatens human survival.
In recent years, various media have paid more and more attention to such a climatological term: El Nino. Many climatic phenomena and disasters are attributed to the ravages of El Ni? o, such as forest fires in Indonesia, heavy rains in Brazil, floods and snowstorms in North America, droughts in Africa and so on. Almost became synonymous with disaster!
Scientifically speaking, El Nino is the product of the interaction between tropical atmosphere and ocean. It originally refers to an abnormal warming of equatorial sea surface, and now it is defined as a global climate anomaly caused by air-sea interaction. This is also the result of human beings themselves. In addition, some data show that:
● The global population will increase by more than 90 million people every year, reaching 6 billion, and will reach 3 billion by the middle of 2 1 century. 30% of the global land is degraded by human activities, and 24 billion tons of soil are lost every year.
● Every year, the world's oil flows into the ocean as high as 6.5438+million tons, with millions of tons of heavy metals and countless domestic wastes.
● Bacteria and pollutants in water kill about 25 million people every year.
● The world emits about 23 billion tons of carbon dioxide into the atmosphere every year, an increase of 25% over the beginning of the 20th century. At the same time, particulate matter, sulfur dioxide, carbon monoxide, hydrogen sulfide and other pollutants in the air have also increased significantly.
● The global forest area is disappearing at an annual rate of about 6.5438+0.7 million hectares, with an average of 654.38+0.40 species dying every day. ...
All this warns us that human beings are destroying themselves while destroying the environment. As far as water resources are concerned, it can be divided into surface water and groundwater, which seems inexhaustible. In fact, according to the current situation of human use, only fresh water is the main water resource, and only a small part of fresh water is available for people to use. Renewable resources in fresh water depend on the earth's water cycle.
With the development of industry and the increase of population, a large number of water bodies are polluted. Groundwater pollution mainly comes from the infiltration of surface water or soil water, agricultural nitrogen fertilizer and garbage oil pollution. Once the nitrate in nitrogen fertilizer enters the ground, it becomes nitrite and becomes carcinogen in human body. Due to the excessive demand of cities and industries, fresh water is continuously pumped out as domestic and industrial water, and then discharged again as surface sewage. Causing the groundwater level to continue to decline; The pollution of surface water is mainly manifested in the laying of drainage system and the increasing use of cleaning agents, which makes the phosphate content in waterways and lakes increase day by day. This overnutrition leads to the rapid proliferation of algae. Consume oxygen in water, kill fish and worsen ecosystem. Due to the improper treatment of mercury compounds and other heavy metals in industry, serious water pollution has also been caused. Mercury gradually concentrates through the food chain, and finally causes serious nerve damage to birds or fish-eating humans.
On the other hand, a large number of frequent irrigation can enhance infiltration and make the groundwater level rise to the surface. In arid areas, the land infiltrated by water will precipitate salt from underground water due to abnormal evaporation, and it will become uncultivated saline-alkali land sooner or later. In the late 1980s, the actual utilization of fresh water in the world was about 300 billion cubic meters per year, accounting for 1/3 of the total available. However, with the increase of population and per capita income, people's consumption of water resources has also increased geometrically.
Can't these phenomena attract our attention? We should remember not to enjoy one kind of happiness while inhibiting another. Let's take a look at Miles Mahon, the urban design and planner of Ottawa Development Service. He said, "One principle that planning and construction should adhere to is: to protect the natural and human environment, we must have long-term goals, not just short-term benefits, but also organically combine * * * policies, expert opinions and residents' opinions. "
This has led to the vigorous rise of green products and brought a glimmer of life to the deteriorating global environment. For example, fluorine-free refrigerators have gradually entered people's lives. Sweden has developed a wind-driven refrigerator whose compressor is driven by a windmill installed outdoors. France produced a refrigerator with solar radiation as energy source and methanol and activated carbon as refrigerants. Chinese scientists and technicians are developing an absorption refrigerator with ammonia, water and hydrogen as the medium, which is driven by heat and keeps the medium circulating. Liquefied gas, coal gas, biogas and kerosene can all be used as its heat energy sources.
Resources and environment-the guarantee of human life
Since the birth of mankind, all the necessities of life, production and life depend on the planet where we live. The atmosphere, forest, ocean, river, soil, grassland and wildlife on the earth form a complex and closely related natural ecosystem, which is the basic environment for human survival. For a long time, human beings have been stuck in the conquest and plunder of nature, and it seems that they never want to protect and repay the earth that feeds them. While achieving brilliant achievements in civilization, human plundering of nature has scarred our planet, and the increase of population and production activities has also caused impact and pressure on the environment.
As we all know, human beings regard the natural environment as the material basis for survival and continuation. However, with the development of modern industry, the natural environment has been destroyed more and more seriously. Air pollution, water pollution, land pollution. . . . . . Then there will never be a pure land in the world.
Maybe you will think it is very important to develop science and technology. It is not too late to go to environmental protection when science and technology are developed. You will regret it then. If we are too intoxicated with the victory over nature and think that we have made great achievements, then we are not far from extinction.
Climate warming, ozone hole, acid rain, toxic waste, wildlife extinction and air and water pollution are a series of global environmental problems we are facing at present. What should we do in the face of these problems?
Protecting the environment is everyone's responsibility, but we are only students now, so we can't make great contributions to the environment of all mankind. However, we can start from the environment around us and protect the school environment, such as observing the regulations prohibiting littering, throwing garbage into designated places or containers, avoiding using disposable beverage cups, lunch boxes and plastic bags, and using paper boxes instead, which can greatly reduce garbage, reduce the pressure of garbage disposal and take care of flowers and plants.
Although these are trivial matters, as long as we work together to save resources, reduce pollution and adjust our way of life, we can make contributions to protecting the earth.
Save resources, protect the environment, and be the little master of protecting the earth.
Expo 20 10 will be held in Shanghai, and its proposition of "Better City" indicates that Shanghai and other cities will use and transform the natural environment to create a highly artificial living environment for the benefit of all urban residents.
2 1 century is a green century. The theme of the World Expo held in Aichi, Japan is "the wisdom of nature". It can be seen that people pay more and more attention to nature and ecology. The dominant residence in 2 1 century is green home, the dominant food in 2 1 century is green food, and the dominant environment in 2 1 century is green environment. Green is also the eternal theme of mankind. Greening is an important link to embody green.
The word greening is not strange to us. As we all know, greening can beautify the environment, release oxygen, reduce noise and temperature, stop sandstorms and improve the environment. Not only that, greening can also reduce people's fear and anger and promote positive psychological reaction. It can be said that greening is an indispensable part of life.
20 10 Expo Shanghai will take greening as the highlight of urban planning. With the countdown to the Expo application, the restless indicators on the dial strike a chord with all those who care about the Expo, especially the staff of Shanghai Greening Administration Bureau, which is closely related to the Expo project. After all, 60%-80% of the 400 hectares bid site will be green space. Greening is very important for the urban construction of Shanghai World Expo 20 10, improving people's quality of life and promoting economic growth.
First of all, greening can promote the urban construction of Shanghai. It is understood that the 20 10 World Expo will have a number of green corridors perpendicular to the Huangpu River, extending the green belt from the riverside area to the hinterland of the city, just like the link between modern cities and nature; Against the backdrop of green trees, a 400-500-meter-long flower bridge dedicated to tourists will cross the banks of Pujiang and become a landmark building connecting the past, the present and the future. After the World Expo, the Expo space will be transformed according to the urban prototype of this area, and it will be integrated into the urban area of Shanghai. Green corridors and canals will be preserved. The flower bridge across the Huangpu River will also be preserved, which can guide tourists to take a walk in a new city park. After the exhibition, it will become another landmark building in Shanghai as a part of the city appearance.
Secondly, greening can improve people's quality of life. On February 2, 2004, Shanghai was officially awarded the title of "National Garden City", and Shanghai also put forward the goal of building a forest city. 1990, Shanghai is still in the debt repayment stage; However, in 2004, Shanghai newly built green space 1.800 hectares, with a green coverage rate of 36%, and the per capita public green space in urban areas reached 10 square meter. Within the inner ring, the green blind area with a service radius of 500 meters has been basically eliminated, and a large number of large public green spaces have been built; Due to the 20 10 World Expo, more urban green spaces will be built. In the construction of green space, not only the ecological function is highlighted, but also the comprehensive service function and urban landscape function of green space are paid more attention to. With this development momentum, by 20 10, Shanghai will reach its goal just around the corner.
Not only that, greening will also bring economic growth. Due to the 20 10 World Expo, the housing prices in Shanghai will rise. According to the data of real estate investment, the most direct beneficiary of green space is the real estate developer: the park green space invested by * * * always revolves around "Zebei"-there is almost no house price near the park that is not "long grass but high price". In recent years, the property price near the park has risen by at least 1000 yuan per square meter, and the average number of sales of buildings near the green space will be much higher than that far away from the green space.
Without a green home, there will be no peace and tranquility. There is no green grass, only a piece of pale road, dazzling pale in the strong sunshine. ...
Water is the source of life, and green is the color of life. Only a green city can be full of vigor and vitality. ...
Green is an eternal concept of human beings.
Green is a symbol of civilization.
Green, it shows the inspiration and charm of nature.
Let's take action from now on to make the city greener and more vibrant.
My 20 10, my Expo!
