The deterioration of the earth's environment has aroused widespread concern, so environmental protection has attracted more and more attention from all countries. However, due to the conflict between environmental protection and economic development and social problems to some extent, the understanding of the concept of environmental protection has become increasingly novel and reasonable in recent years.
Environmental protection is to protect the living environment of human beings from pollution and destruction by taking administrative, legal, economic, scientific and technological measures. We should also protect and improve the environment according to human wishes, make it more suitable for human labor and life and the survival of natural creatures, and eliminate the unfavorable factors that destroy the environment and endanger human life and survival. The problems to be solved in environmental protection generally include two aspects: one is to protect and improve environmental quality, protect human physical and mental health, and prevent organisms from mutating and degrading under the influence of the environment; The second is to make rational use of natural resources, reduce or eliminate harmful substances from entering the environment, and protect the restoration and expanded reproduction of natural resources (including biological resources) in order to facilitate human life activities.
Of course, environmental protection must also consider economic growth and social development. Only the coordinated development of the two is the new concept of environmental protection in the new era.
The quality of environmental protection is directly related to the stability of the country, and it is of great significance to protect the reproduction of social labor from destruction.
With the deepening of human understanding of the environment, the view that the environment is a resource is more and more accepted by people. Air, water, soil, mineral resources, etc. It is the natural wealth of society, the material basis for developing production and the constituent elements of productive forces. Due to serious air pollution, canned air is sold abroad; Water shortage occurs in many parts of the world due to water pollution, climate change and over-pumping of groundwater. Due to the rapid increase of population, the abuse of cultivated land, land desertification, land shortage and so on. It can be seen that failure to protect the environment and environmental resources will threaten the survival of human society and also affect the sustainable development of the national economy.
At the beginning of this century, industrialized countries only paid attention to economic development, neglected environmental protection and sought economic development at the expense of the environment. When pollution became a public hazard, aroused strong opposition from the broad masses of the people and affected the smooth development of the economy, it was forced to control it and paid a high price. Later people call it the development road of "pollution first and then treatment" This development model will not only slow down the development of national economy, but even destroy the material foundation of national economic development. On the other hand, if human beings do not act according to the laws of environmental science and wantonly destroy the ecological environment, they will inevitably be retaliated by the environment. Statistics show that the forest coverage rate of 1950 in Yunnan province is 50%, and it suffered a serious flood and drought disaster in 9 years on average. Due to deforestation and other destruction, the forest coverage rate is only 24.9% to 1980, which affects the regulation of climate. During 1950 ~ 1980, there were 1 1 disasters, which seriously damaged agricultural production. This is the revenge of the environment on mankind.

Protecting the environment is everyone's responsibility. Students, do you know? China is the largest developing country in the world, with the largest population and low per capita resources. For example, the total amount of fresh water resources in China is 2.8 trillion cubic meters, which sounds like a huge number. But, students calculate, divide this figure by 65.438+0.4 billion, what is the result?
China's per capita fresh water resources are only 2.8 trillion cubic meters, which is really pitiful. It is 1 of the world average level and 1 of the United States. Today, the northern part of China is suffering from a drought once in 30 to 50 years. According to the news released by the Ministry of Agriculture, the drought-affected area of crops in China is 65.438+0.46 billion mu. About 43% of winter wheat in China suffers from drought. There are 3.98 million people and 6.5438+0.95 million large livestock who have difficulty drinking water due to drought. From TV, we also saw that many rivers dried up and many originally green winter wheat turned into hay. So what caused the drought in the north?
The direct reason is that there has been no rain or snow in some places for more than 100 days, which is caused by drought and water shortage. This shows how important the relationship between water and people is! We know that water is one of the important resources for human survival and development, and it is an indispensable and irreplaceable special resource. Without water, there would be no life and no progress of civilization. However, China is extremely short of water resources, and the per capita water quantity in the world is 109. If we don't make rational use of water resources, we will face a crisis of fresh water resources and people will not get clean drinking water.
This is nature's punishment for human destruction of the environment! Shouldn't we wake up? We once praised our motherland in this way: vast territory and abundant resources, magnificent mountains and rivers. However, when we now face our beautiful motherland: a place once surrounded by green mountains and green waters. People cut down and cut down, the beautiful mountains disappeared and the gurgling streams dried up. Now, we can't see green mountains and green waters here ... teachers and students. Facing the national conditions, what should we do for the sustainable development of the country?
We should save every drop of water, insist on turning off the tap at hand ... and actively look for tips on saving water and recycling domestic water. Students, this is not just about saving water. We are the little masters of the earth, and each of us should have a sense of environmental protection since childhood. Protecting the environment is our unshirkable responsibility.
We should start from now on, from around us, and from small things: love makes the sky bluer, the land greener and the water clearer in our motherland through our efforts.

With the continuous development of society, environmental problems are not uncommon, and environmental problems have also attracted people's extensive attention. People have realized the important role of environment in human development and progress. Practice has proved that the environment plays an irreplaceable role in the development of human society. Therefore, each of us should pay more attention to environmental protection, cultivate environmental awareness and do our bit for environmental protection.
The development of human society is a long historical process. In the development of human politeness, we have experienced three periods of politeness.
From the primitive slash-and-burn ritual system to the intensive agricultural ritual system, and then to the mechanized and electrified industrial ritual system. It is not difficult to find that in the evolution of human politeness, the damage to the environment is becoming more and more serious, and the impact on the environment is also increasing. In the primitive ethical code era, people regarded nature as the object of reverence. People think that "oneself is an inseparable part of nature". The relationship between people and between people and nature is harmonious. The primitive politeness period did relatively little damage to the environment. In the period of agricultural civilization, people rely on the power of nature to realize their own progress and development. The relationship between man and nature began to move from harmony to opposition, and man and nature began to move towards opposition. During this period, anthropocentrism began to sprout. The destruction of the natural environment by human beings is becoming more and more serious. During the period of industrial civilization, its development was characterized by mechanization and automation, and the mode of production changed from manual production to mechanical production. The extent of human destruction of nature also reached the necessary level during this period. Exposed a series of problems. For example, global climate deterioration, ozone layer destruction, acid rain generation, accelerated species extinction and other issues. These problems have seriously affected the progress and development of human society. Engels once said: "We should not be too intoxicated with our victory over nature." Every victory that nature wins for us is revenge for us. It's time to reflect on the relationship between man and nature and find the harmony between man and nature. We should be soberly aware that human beings are small and their position in front of nature is correct. So we need to establish protection.
Understanding of the environment, from now on, from scratch.
Protecting the environment is a top priority. This requires the efforts and perseverance of each of us to gradually improve the environment. The harmony between man and nature should come from harmony. We should thank nature.
Protecting the environment is everyone's responsibility. Each of us has raised our awareness of environmental protection and participated in environmental protection actions. Environmental problems will gradually improve. The future of mankind will be more brilliant.

Over the years. Our country has been seriously polluted by the environment. Extraordinary sandstorms have occurred repeatedly in our country, seriously affecting people's lives and making it difficult for us to survive.
Green grass will become a desert, trees will fall to the ground forever, and we will not live happily: happiness will be gone, relatives will be gone, and even the earth we live in will disappear into the vast universe. However, this is not just a disaster caused by sandstorms. At the moment, even the South Pole is polluted and destroyed. Therefore, the earth has lost the last piece of pure land. Mount Tai was originally a good place for people to watch, but it has also become a protected area.
And we can only stand by and watch this beautiful and fragile earth disappear forever? From then on, can we see the wind blowing and grass watching cattle and sheep, and can we see horses running under white clouds? Although we are only primary school students, we can still make some contributions to our hometown and make Dingxi rise in expectation.
I heard from my father that there is a Lop Nur on the edge of Taklimakan desert, which is a vibrant oasis. There will be fresh air all year round, a desirable environment, an environment surrounded by greenery and covered by jungle, which will make people living there rekindle their expectations for an oasis life in the desert. But who can understand that the holy land, which lasted for hundreds or even thousands of years, was actually disappeared and destroyed by the fools there. The death toll is increasing one after another, and the forest has been seriously polluted by the air because the rotting bodies are not buried, and the forest is disappearing day by day. Through the sunshine that almost scorched the earth, we can see the pain of Lop Nur! Is missing, missing the past cattle and horses, green mountains and green waters; It is sighing, sighing yellow sand and Wan Li, dead trees and dead branches; It is the yearning for the source of life and the root of all things. However, human beings, a huge water-absorbing ghost, cut off its last hope. As a result, the long green embankment built with the desire for life collapsed. ...
April 22nd is a festival of the earth every year. It has been 30 years now. Because of the "three wastes" pollution (waste water, waste gas and waste residue) and the "top ten pollution", a large number of people all over the world get sick, disabled and even die every year. However, white pollution is free. It runs amok in the sky, piercing the clothes of Air Brothers and Ozone Brothers, making the sand in the desert fly forever and disturbing people's lives. Uncle naturally did not dare to object, and left people in a hurry. If we can't stop it, white pollution will severely punish mankind. In the end, not only rare animals and plants, but also human beings will eventually become extinct in the desert.
Students, we can't live without the earth. We are bound by the same fate. Uncle nature expects it to go home. Mother Earth entrusts the heavy responsibility to mankind, because only we can save the happiness of the earth and mankind: let the green stop sighing, let nature stop crying, let the scars of Mother Earth disappear, and make the earth more beautiful, strong and lovely tomorrow!
