Overview of environmental pollution
Due to people's insufficient expectation of the negative impact of highly developed industries and unfavorable prevention, three global crises have resulted: resource shortage, environmental pollution and ecological destruction. Humans constantly discharge pollutants into the environment. However, due to the diffusion, dilution, redox and biodegradation of atmosphere, water and soil, etc. The concentration and toxicity of pollutants will naturally decrease, which is called environmental self-purification. If the discharged substances exceed the self-purification capacity of the environment, the environmental quality will change adversely, endangering human health and survival, thus leading to environmental pollution.
There are many classifications of environmental pollution:
According to environmental factors: air pollution, water pollution and soil pollution.
According to human activities: industrial environmental pollution, urban environmental pollution, agricultural environmental pollution.
According to the nature and sources of environmental pollution: chemical pollution, biological pollution, physical contamination (noise pollution, radioactivity, electromagnetic wave) solid waste pollution, energy pollution.
Environmental pollution will cause direct damage and influence to the ecosystem, such as desertification and forest destruction, and will also cause indirect harm to the ecosystem and human society. Sometimes this indirect environmental impact is more harmful than the direct harm caused at that time, and it is more difficult to eliminate. For example, the greenhouse effect, acid rain and ozone layer destruction are all environmental impacts caused by air pollution. This kind of environmental effect from environmental pollution is lagging behind, and it is often difficult to be detected or predicted when pollution occurs. However, once it happens, it means that environmental pollution has developed to a very serious degree. Of course, the most direct and easily felt consequence of environmental pollution is to reduce the environmental quality of human beings and affect their quality of life, physical health and production activities. For example, urban air pollution causes air pollution, and the incidence of people is rising. Water pollution worsens the quality of water environment, and the quality of drinking water sources generally declines, threatening people's health and causing premature birth or malformation of fetus. Serious pollution incidents not only bring health problems, but also cause social problems. With the intensification of pollution and the improvement of people's awareness of environmental protection, disputes and conflicts between people caused by pollution have increased year by year.
At present, environmental pollution problems have appeared in different degrees all over the world, including atmospheric environmental pollution, marine pollution and urban environmental problems. With the globalization of economy and trade, environmental pollution is becoming more and more international. In recent years, the problem of transboundary movement of hazardous wastes is a prominent manifestation in this regard.
Protect the earth, starting with me.
Throughout the ages, Mother Earth has raised countless generations of children and grandchildren with sweet milk. It turned out that she was beautifully decorated by junior students. However, now human beings have tortured her to death for their own interests. There is only one earth for mankind; The earth is facing a serious environmental crisis. "Save the Earth" has become the strongest voice of people all over the world.
I feel heartache for the deterioration of the surrounding environment. I think: if teenagers, as future successors, don't understand the composition of human environment and the seriousness of environmental problems, ignore the laws and regulations on environmental protection, don't enhance their awareness of environmental protection, and don't consciously fulfill their obligations to protect the environment, our lives will be destroyed in their own hands, and God will severely punish us. To this end, I am determined to start from myself, protect the environment, protect our homeland and be a guardian of the environment.
In the past year, I actively participated in the tree planting activities carried out by the school, led the class cadres of our Senior One (6) Squadron to set up a "Green Angel" tree planting and green protection group, encouraged the team members to adopt a small sapling on campus, and used their spare time to decorate it carefully, laying the foundation for it to grow into a towering tree. In the signature activity of "Let the Earth Be Full of Life" organized by the school, I solemnly signed my name on it, writing down my determination and expectation for environmental protection and my vision for a better future. I actively participated in the prize-winning essay-writing activities held by the school in World Environment Day, carefully consulted and collected various materials, conducted social surveys, and wrote articles on environmental governance. I often take part in environmental protection lectures organized by the school, watch environmental protection videos, actively participate in environmental protection knowledge quiz activities, and fill in each question carefully. I participated in the website construction of "Green Team with Red Scarf", and posted many pictures and knowledge about environmental protection, as well as legal knowledge about various aspects of environmental protection, the development trend of environmental protection in China, and the environmental protection situation around the world. Every month, I will use the internet and newspapers to find some latest "environmental information" with different themes and sections to tell you; We also make some publicity boards regularly to publicize environmental protection knowledge and common sense of life. Raise everyone's awareness of environmental protection; Call on students to take care of their homes from different aspects, start from the little things around them and make contributions to the surrounding environment! I actively mobilize people around me to protect and build the same and only home of mankind according to law, promote the sustainable development of economy and society, and make contributions to human civilization. Together with my classmates, I also launched the initiative of "raising a potted flower, adopting a tree, cherishing every green space and making our surroundings full of green" and "replacing foam lunch boxes and disposable chopsticks with small plastic bags to keep us away from white pollution". Let's put down the convenient bag and pick up the vegetable basket. Let's move towards a bright green tomorrow and a brilliant future!
According to a report I collected, "environmental problems are caused by unreasonable development and utilization of natural resources by human beings." Shocking environmental problems mainly include air pollution, water pollution, noise pollution, food pollution and improper development and utilization of natural resources. "Iron facts tell us that they are ruthlessly devouring human life like demons. It threatens the ecological balance, harms human health, restricts the sustainable development of economy and society, and puts human beings in a dilemma. To this end, I issued a declaration: "As long as we humans always have the awareness of protecting the environment and managing the environment according to law, the global village will become a beautiful paradise". The sky in the future must be blue, the water must be clear, the trees are shady and the flowers are everywhere, and human beings can enjoy the happiness endowed by nature.
"The real test of our contribution to the environment is not words, but actions." Although what I am doing now is just a small thing, I firmly believe that if we all have the responsibility to protect the environment, start from ourselves, start from small things, and work together to protect our homeland, we will naturally give humanity the due return. Take a nap in the warm cradle-grassland; Grow up under the kind smiling face-the sky, and bathe in the river, the source of love.
* * * Building a harmonious blue sky on campus
Harmony, what beautiful words, what beautiful artistic conception. Please let us feel harmony together: the spring breeze is harmonious, it melts the hard ice, revives everything and brings people a beautiful season; Spring rain is harmonious. She "sneaked into the night with the wind and moistened things silently." Throughout the ages, the idea of harmony has been heard all the time. From Confucius' advocacy of "courtesy, harmony is precious" and "harmony is different" to Mencius' assertion that "weather is not as good as geographical location, and geographical location is not as good as human harmony"; From Hong Xiuquan's ideal scheme of "sharing farmland, having clothes, food and wealth" to Kang Youwei's social state of "everyone is blind, everyone is equal, and the world is public", from Sun Yat-sen's ideal of "one family under the sun" to Mao Zedong's pursuit of "the world is cool and hot", thinkers and politicians in China have advocated unity and mutual assistance for thousands of years. Harmony means harmony and harmonious development. A harmonious society should be a society of unity, friendship and mutual assistance. However, in real life, due to the differences in ideological consciousness, values and hobbies of many students, some people's behaviors are not conducive to unity and mutual assistance, and even sometimes there are some phenomena that harm others and benefit themselves; Some students like to engage in small liberalism, not talking in person, behind their backs, not talking in class, and talking outside school, which leads to mutual suspicion and discord among students; Some students even put some things into the society: mercenary, harming others and taking advantage of others; Even cheating and cheating are brought to campus more or less, which is not only shameful, but also a moral prisoner. As an important part of the socialist concept of honor and disgrace, General Secretary Hu proposed that "we should be proud of unity and mutual assistance and ashamed of harming others and benefiting ourselves", which enriched the content of socialist moral construction and campus culture. What we middle school students should do today is; Students should be harmonious, United, friendly and helpful; The campus should be harmonious and build a harmonious campus of unity, friendship and civilization. Historical experience has repeatedly told us that whether there is a moral fashion of solidarity and mutual assistance is one of the important signs to judge whether a group is healthy or not and whether a society is harmonious. A very important aspect of inheriting the excellent traditional culture of the Chinese nation is to carry forward the virtues of unity, friendship, mutual assistance and love. Yes! China is known as "a country of etiquette" and stresses the traditional virtues of kindness, friendliness and harmony with others. Our new generation of middle school students should inherit these traditional virtues, work hard for building a harmonious campus today and pay for building a harmonious society tomorrow, which is the heavy responsibility entrusted to us by history! This is the mission entrusted to us by the times!
Environmental protection, starting from the little things around us. ...
Environmental protection is not a new problem for us, and our government has already put forward a clear governance goal. As every ordinary person in real life, although it is impossible for all of us to directly engage in environmental protection work, we can start from small things and start from me. When you see the faucet dripping in the bathroom, can you raise your hand and turn it off? The battery is used up, can it be collected separately instead of thrown away? Can you consciously not use ultra-thin plastic bags when shopping? ..... Although every little thing is insignificant, it shows how much we are aware of environmental protection.
I know an old lady who takes a small cloth bag every time she goes shopping and a small steel spoon every time she goes to a restaurant. It looks ordinary, but it is really not easy for this old comrade to consciously insist on not using white plastic bags and disposable chopsticks for many years. This requires not only a firm belief in environmental protection but also good habits. There is no doubt that environmental awareness is closely related to people's education level, and it is easiest for us to find supporters of environmental protection on university campuses. However, we can often find a lot of leftovers in the trash can of the university cafeteria. The author also heard that there was such a college student who was enthusiastic about environmental protection and went to the Yunnan border to protect the golden monkey, but he forgot to turn off the tap in the water room several times. This reminds us that it is not easy to protect the environment in an all-round way and popularize and improve the environmental awareness of the whole nation. Environmental protection includes not only protecting animals and forests, preventing air and water pollution, but also all kinds of small things that are everywhere in our lives.
In the final analysis, human protection of the environment is based on the protection of the increasingly depleted resources on the earth and the minimum conditions for our survival and development. When industrial civilization entered the 2 1 century, its damage to the environment became more and more serious, and the utilization of resources became abusive, which aroused more and more vigilance. Governments of various countries have taken many measures to protect the environment, and great progress has been made in environmental protection, which has become the knowledge of human society. Up to now, when it comes to environmental protection, few people will openly oppose it, but there is still a lot of work to be done to really protect the environment and resources consciously and for a long time. I think we should first establish the awareness of environmental protection in the whole nation, specifically, we should establish the awareness of resources and survival. Let everyone realize that protecting the environment and resources is closely related to each of us. Protecting the environment is not only a great cause for future generations, but also directly related to the survival of human society today! You can't hold the idea that there is little difference between environmental protection and environmental protection, you can't relax, and you can't be afraid of trouble. Of course, government departments have an important responsibility for environmental protection, and every unit, every enterprise and everyone has a more direct and specific responsibility for this. As long as we start from ourselves and start from small things, we will work together and persevere, which will definitely leave a clear water and blue sky for the society and ourselves. At this point, middle school students in Beijing gave us many good suggestions. Is there anything we should hesitate about?
