The soil was destroyed. At present, the arable land fertility in 1 10 countries is declining. In Africa, Asia and Latin America, soil erosion is very serious due to the disappearance of forest plants, over-exploitation of cultivated land and overgrazing of pastures.
Air pollution. Air pollution is also a problem of acid rain. In the past, the problem of acid rain only involved the old industrial countries in Europe and North America. But now, some areas in Asia and Latin America, where the economy is developing at a high speed, are also harmed by acid rain. Air pollution will also disturb the normal operation of the ecosystem, accelerate the damage of houses, and lead to abnormal climate change.
Fresh water is threatened. In developing countries, 80%-90% of diseases and more than 65,438+0/3 of deaths are related to water infected by bacteria or chemically contaminated. Now, 25,000 men, women and children die of water-borne diseases every day.
The greenhouse effect and energy waste of climate change are serious threats to all mankind. According to 2500 representative experts, the sea level will rise. Rising temperatures will also have a serious impact on agriculture and ecosystems.
The forest area has decreased. In the past hundreds of years, countries in temperate regions have lost most of their forests. In recent decades, the forest area in tropical countries has also been seriously reduced. According to the current rate of forest area reduction, it will be difficult for some Southeast Asian countries to see forests in 40 years.
The number of biological species has decreased. Due to urbanization, agricultural development, forest reduction and environmental pollution, the natural area where organisms live has become smaller and smaller, leading to the extinction of thousands of species.
Millions of compounds brought by chemical pollution industry exist in air, soil, water, plants, animals and human body. Even the ice sheet, the last large natural ecosystem on earth, has been polluted.
The explosion of urbanized population, the deterioration of agricultural land and poverty have prompted millions of farmers in the third world to leave the countryside and gather in slums in big cities.
Living conditions in big cities will further deteriorate.
(1) Prevention and control of environmental pollution caused by production and living activities, including prevention and control of "three wastes" (waste water, waste gas and waste residue), dust and radioactive substances discharged from industrial production, noise, vibration, odor and electromagnetic microwave radiation, harmful gases, waste liquid and noise generated from transportation activities, pollutants discharged from ships at sea, toxic and harmful chemicals used in industrial and agricultural production and people's life, and smoke and dust discharged from urban life.
(2) Preventing environmental damage caused by construction and development activities, including preventing environmental pollution and damage caused by large-scale water conservancy projects, railways, highway trunk lines, large-scale ports and docks, airports and large-scale industrial projects, and preventing environmental damage, pollution and impact caused by land reclamation around lakes, development of offshore oil fields, coastal zones and swamps, development of forests and mineral resources, and establishment and construction of new industrial zones and new towns;
(3) Protecting the natural environment with special value, including effectively protecting rare species and their living environment, historical sites of special natural development, geological phenomena, landforms and landscapes, etc.
In addition, urban and rural planning, controlling soil erosion and desertification, planting trees, controlling population growth and distribution, and rationally allocating productive forces also belong to environmental protection. Environmental protection has become one of the common actions and main tasks of governments and people all over the world. China declared environmental protection as a basic national policy, and formulated and promulgated a series of environmental protection laws and regulations to ensure the implementation of this basic national policy.
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 made 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". In the future, the sky will be blue, the water will be clear, the trees will be shaded, and the flowers will be everywhere. Humans 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.
Yellow Sunday
Xi 'an Liang Shu, Xi 'an Liang Shu? V gray? What about Huaihuai? ○ ○○○?????????????????????????96
On the morning of Sunday, April 7, I was surprised when I opened the curtains. I see the sky outside is not as blue as before, and the sun is not as bright as before. Those tall buildings in the distance are as dim as a mirage. Under the influence of the sandstorm, people in the building lit the lights to illuminate themselves. The boundary between heaven and earth is not so clear, but muddy yellow. People in the street are armed to the teeth, covered with headscarves and covering their mouths. I'm afraid that sand will enter my respiratory tract. As soon as you walk out of the house, the smell of sand comes to your face, and a gust of wind blows, feeling the sand hitting your face, big and small. Suddenly, my clean face was painted with a layer of khaki glaze, and my face was dressed as an aboriginal face. I looked down, and the earth was dressed in khaki. After a while, it began to snow again. Many people are very happy. They think snowflakes are white and beautiful. But they were wrong. Today's snowflakes fall on people like bombs, blowing up "yellow flowers" one after another. It's embarrassing. I was "bombed" like Xiaoyan.
Today's scene makes people once again see the consequences of destroying the environment. Under the reminder of the disaster, people have realized that it is urgent to follow the laws of nature and care for our living environment. I believe that with the continuous progress of science and technology, through the continuous efforts of all mankind, planting trees, protecting the environment and maintaining ecological balance, the frequency of disasters will gradually decrease. The beautiful face of the earth will reappear before our eyes!
Humans, there is only one earth.
I love the earth and the home where we live. Love her mountains and waters, love her green grass and blue sky. ...
I played and laughed with butterflies among the fragrant flowers in the four fields; In the lush forest, I chase and sing with birds; Early in the morning, I went for an outing in Yuan Ye with light steps. The mist filled the air, like a piece of white gauze floating gently in the air. Sucking the flowers and enjoying the sunshine bath, I am intoxicated in this ecstatic dream; In the evening, I sat in a farmhouse with fragrant rice, looking up at the bright stars and listening to cicadas and frogs, as if I were in a fairy tale kingdom. In spring, I sit on the back of a cow and listen to the pastoral melody and melodious flute on the endless grassland. In summer, I sat in a boat, paddled the green lake, and watched the seagulls skim across the vast lake lightly; In autumn, I stand under the tree, expecting the golden leaves to fall one by one; In winter, I stand at the window and admire the snowflakes flying in the air. My heart is drunk in this picturesque fairyland!
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, and nature's revenge has embarrassed mankind. Meishuixi once said that there would be no human beings without nature, which is the simplest truth in the world. Blindly plundering and conquering nature will only destroy the ecosystem and bring mankind to the brink of difficulties. This sentence is absolutely true. People don't give face to nature, and nature certainly won't give people a way back. In fact, the flood in 1998 and the sandstorm in 2000 were both warnings issued by nature to human beings.
Once upon a time, people arrested and killed indiscriminately, which made human friends suffer greatly. "There are no birds in a hundred mountains, and there are no footprints in a thousand paths", which is the truest portrayal of the consequences of killing animals. From the bear injury of college students to the crazy hunting of fools, will humans also point their guns at themselves? Remember, protecting animals means protecting ourselves.
Once upon a time, the outbreak of war left our planet devastated. Although the mushroom cloud over Hiroshima and Nagasaki has dissipated for more than half a century, nothing grows. Therefore, peace is an important prerequisite for environmental protection of all mankind.
I can't imagine how miserable the world will be if we continue like this. Nothing grows on the ground, the sky is full of dust, and human beings will become piles of bones in the scream of the devil. At that time, we could only say that man once belonged to the earth, but the earth will never belong to man again.
Gu once said that every man is responsible for the rise and fall of the world. The historical responsibility of protecting the environment and maintaining ecological balance should fall on our cross-century generation. Let's all care about nature, love the earth, hand in hand, shoulder to shoulder, heart to heart, and build a green levee to defend resources, environment, the earth and our beautiful home!
Qijiangqing
Qijiang, my mother river, meanders from north to south. I grew up in her arms. She gave me childhood happiness. I spent the happy time of my golden childhood with Qijiang.
I remember that when I was only the size of a bean, I watched Zhao Hui jump on the river for countless mornings, reflecting the clear river red, like wearing a red scarf for Qijiang, and the lush banyan trees around me also put on dressing gowns. Groups of men, women and children stroll along the river, enjoying the fresh air and the morning songs played by the breeze of birds.
During the Dragon Boat Festival, there will be wonderful dragon boat races on the river. People came one after another, scrambling to gather by the river to watch the excitement. Dragon boats are neatly arranged on the river, and every big man with bronzed skin on board tries his best. After each salute, dragon boats go hand in hand and set off river waves. Some people stamped their feet by the river, some people cheered loudly, some people craned their necks like giraffes ... The dragon boat in the river broke through the waves, accompanied by the sound of gongs and drums. ...
The happiness of my childhood was immersed in the clear blue waves of the Qijiang River. As long as the breeze blows, all good memories are spun from the rippling blue waves. Now, when I greet Qijiang alone, it has changed beyond recognition: the polluted river water is mixed with a lot of garbage, and occasionally one or two dead fish float up, emitting an intoxicating stench. Green, gone, bird, I can't hear you. The river is full of piles of rubbish, and the fresh and fragrant breeze of the past has become dirty and bitter. I cried sadly to Qijiang, "Where have you been?" But it just beat the river bank with waves, groaned like a dying patient and cried sadly to people: "Please help me!" " "
Perhaps because of its beauty in the past, perhaps because of its ugliness now, perhaps because of the requirements of the times, Qijiang's cry for help has finally been answered. The municipal government attached great importance to the renovation of the Qijiang River, organized manpower and material resources to demolish dilapidated buildings on both sides of the Qijiang River, planted green trees and red flowers on the banks of the river, and prohibited people from dumping garbage into the river and discharging sewage into the river. Qijiang began to regain its vitality and reappear the beautiful scene of the past. I think: Over time, my mother Heqijiang will take care of our home more than before.
The cradle of our life is Mother Earth. Mother Earth has mountains and oceans, plateaus and plains. The most precious thing is that it has life. We humans live on the earth, and we are the masters of the earth.
The earth is the home of all living things and the environment on which we live. Mother Earth can provide us with food, clothes, uses and games. Mother Earth nurtures her children with her sweet milk, and we grow up happily in the warm embrace of Mother Earth. Why can we live happily on the earth? Because Mother Earth can provide us with enough oxygen, enough water and enough food ... She is a good mother who cares and loves her children.
However, how do we humans treat Mother Earth? For our own survival, or for a better life, we ignore Mother Earth's body, factories discharge sewage indiscriminately, chimneys emit thick black smoke, cut down trees indiscriminately, and waste resources indiscriminately. Destroyed the large oxygen layer around the earth, clear rivers became turbid, dense forests became flustered, blue sky became gloomy, green hills became bare, mudslides, forest fires, animal extinction, serious water shortage, and a series of disasters followed, which made our mother earth unbearable. And we are facing the reality of the destruction of the earth. Ah! It's terrible. We don't know what to do next. How will we survive?
We have seen the serious consequences, can we let them be destroyed? Can't! We humans should take active actions to do something good for our planet. Now we have begun to protect our environment and care for our planet. For example, we built hydropower stations and wind power stations, and began to protect wildlife, forests, water sources and water conservation, and began to green and beautify our planet. This is gratifying, it can prolong the life span of our mother earth and make her younger and healthier. What should we do the night before the earth is destroyed? We should protect and care for the earth, green and beautify the earth, and make our mother earth young forever.
Let me ask you one more question, son. Will the earth be destroyed? It depends on how we cover her up. If we love her like our own eyes, I believe she will be young forever.
Give me back the green mountains and green waters.
