Debate on caring for the environment in senior three 1
Our beautiful home, the earth, selflessly dedicates its precious resources to human beings, but while human beings claim the resources of the earth, they wantonly destroy the ecological environment of the earth.
Take the water that we can see every day! 50% to 60% of the weight in the human body is water. Without water, there is no life. The fresh water resources on the earth only account for 3% of the total water resources on the earth, and only 0. 5%。 Therefore, water is a precious resource for human beings and the source of life. However, water pollution is quite common and serious in the world.
Once upon a time, the Mulan River in my hometown was full of spring, green grass, flowers and birds all year round. People often wash clothes, fish and walk by the stream here ... the stream is full of laughter. However, the good times did not last long. In recent years, this stream is no longer as beautiful as it used to be. The stream is muddy, smelly and filthy now. Garbage floats on the water, and all the fish are dead. All this is caused by people. This stream has been ruined beyond recognition and is dying. It moans sadly to people ... not only the Mulan River in my hometown has been "poisoned" by human beings, but also many rivers and lakes have been polluted.
There is a French fable: "There is a big lily in the pond, which grows twice as fast every day. If it is not restricted, it will cover the whole pond within 30 days and suffocate the creatures in the water. Humans won't realize this danger until they are 29 years old-because lilies have covered half the pond. However, how much time is there to save the pond?
Not only water resources are polluted, but also clean air, one of the three elements of human life and health, is doomed. Reducing pollution and purifying the air, "Give me back my blue sky and red sun" has become the common aspiration of people all over the world.
With the rapid development of modern science and technology, we humans have invented vehicles such as cars, planes and trains. Although this is a great pioneering work in our history, it has also brought us great harm. Carbon dioxide emitted by factories and cars is a colorless and odorless toxic gas, which is not only harmful to human health; It also brought huge losses to agricultural production. A small amount of carbon dioxide gas will affect the life function of plants. Once the rice is fumigated, the yield will drop by 85% and 9%. From this perspective, we must protect and cherish the atmospheric resources.
The levee of a thousand miles was destroyed in the ant nest. Now the earth is sick, riddled with holes and ugly. Do we realize that the time to try our best to save the earth is short?
Our earth is so lovely and fragile. Man is the best doctor. In order to save the planet on which human beings live, and also to save themselves, let's take action and protect the environment together!
Discussion on environmental protection in senior three II.
Everyone will say that "protecting the environment is everyone's responsibility", but who has really done it? Now on the road, waste paper, garbage and some peels can be seen everywhere ... these are thrown by people from all over the world.
Now the "global village" is full of smoke, and the endless blue sky is turned into gray by the plumes of black smoke from the chimneys in the factory; People throw garbage, so that "Mother Earth" clothes are covered with garbage; Many places are short of water, but when we walked into the school bathroom, there were too many faucets, and precious water resources flowed away bit by bit. Some students even had a water fight in the toilet. We are facing a water crisis. Let's act together to protect our beautiful green home!
Some people, in order to covet their own selfish desires, add some substances that are harmful to the human body to seek benefits that they do not deserve, causing food poisoning, illness and death to their compatriots. We should despise these shameless people, and the law should stop these bad behaviors. Those who only think about money should stop hurting their compatriots!
In the vast universe, our earth is just a small dust, but it has made our home, and the homes where all kinds of life exist have been hurt again and again by us. Those of us who love environmental protection and peace want to see lush trees and a world without war, but what we are facing now is desert, wilderness and shrapnel ... I think the government should promote environmental protection.
Animals are good friends of human beings, but some cruel people are committing violence against them, beating dogs black and blue and breaking cats' hands and feet. I really don't know how they did it. Why don't they think about it if they are beaten? What would that be like? Let's fight against those who treat our good friend-small animals with violence!
How common green is in the countryside! When you live in the country, come and see our smoky city again. What a striking contrast! There is a green paradise on one side and a dirty big city on the other. Let's protect the "global village" together!
Debate on caring for the environment in senior three 3
I remember a few years ago, my parents took me to visit my grandmother. There is a river in front of my grandmother's house. The river is clear, shining with golden light, and slowly flows forward. By the river, a group of aunts are washing clothes with a smile, and a group of children are swimming and playing in the river. My mother and I rolled up our trouser legs and went to the river to pick up pebbles, while my father was fishing leisurely. I still remember this peaceful and peaceful scene.
However, one day a few years later, when I saw the river again, I was startled. The river is not clear, the water is turbid and mixed with some dirty things. On the bare riverbed, the water is almost exhausted and stinks. Where did this smelly water come from? Looking around, I saw several factories spewing smoke into the sky, polluting the white clouds, and then turning into acid rain, poisoning the earth; At the same time, the factory also continuously discharges waste water into the river, turning the clear river water into turbid poisonous water. Coal is solar energy stored in nature for hundreds of millions of years, but it has to be developed and utilized after hundreds of years. A large amount of coal is burned to produce carbon dioxide, which has caused the global greenhouse effect. At the same time, a small amount of sulfur in coal burns to produce sulfur dioxide gas, which falls to the ground with rain and forms acid rain. Acid rain destroyed a large number of forests and became the "air killer" of the ecosystem.
The water in the drainage field kept discharging sewage into the river, and even the plants along the river died. Isn't this a dump? The original clean river is no longer clean, the river is no longer flowing, and the air is no longer fresh. What kind of attitude do people have towards this old river that has accompanied them for many years? Should we continue to pollute the environment or protect rivers? Are you a destroyer or an environmentalist?
Due to the pollution of water sources and the over-exploitation of groundwater, human fresh water resources have begun to be in a hurry. Due to deforestation and excessive reclamation, the problems of grazing, soil erosion and land desertification are becoming more and more serious. Due to the destruction of the earth, 20,000 to 30,000 species of plants and more than 1000 species of vertebrates were extinct by 2000, and now 1 species of creatures disappear from the earth every hour. Land pollution, human cutting down trees, rocks falling, floods destroying houses and flooding crops; People throw garbage into the river, causing water pollution, and discarded plastic bags can be seen everywhere, forming white pollution. People kill animals indiscriminately, leading to the extinction of animals; People pick flowers and trees indiscriminately, which makes us lose our beauty. There is only one earth for mankind. If we live on the earth, we must protect the earth and protect our home.

The earth is our home and our mother. We rely on it and explore it. How beautiful this blue planet is, but you know, there is only one earth!
Regrettably, many people turn a blind eye to this simple truth and continue to do whatever they want, regardless of the safety of the earth's homeland. Qu, an environmental scientist, once said: "Only change can save the fate of mankind, and only change can make our descendants survive." One of the "changes" is environmental protection. That's right, so now many people are holding slogans and shouting empty slogans in the street, but they don't see much action. Will the pollution get better? Don't!
You see, the rivers in our city are black and smelly; Long queues of cars emit a lot of exhaust gas; A piece of green land has become a "stone forest"; The crisp birdsong disappeared without a trace. In this way, China will continue to be short of water, the air will become more and more turbid, and 10% of bird species will disappear in this century. The above things, we humans are the culprit!
Everyone knows that trees can absorb carbon dioxide, release oxygen and purify the air, which is a necessary condition for our human survival. However, some people cut down trees for money, which leads to excessive soil erosion, serious damage to the earth's vegetation, and desertification of oases and cities, threatening our human survival. As for the disposable chopsticks we usually use, it consumes dozens of acres of forest every day. In the eyes of those people, trees seem to have no value except for furniture and building materials. Does anyone not understand what trees mean to us? Our living area is already very small. If we go on like this, we may even lose our only land. In addition, the Yellow River, our mother river, has become one of the most polluted rivers in China in recent years. We can't watch the Yellow River dry up from our hands, so many environmentalists have studied plans to control the pollution of the Yellow River and tried to improve its water quality. However, without our participation, the Yellow River, the cradle of our life, will run dry and die.
If we destroy the environment again without restraint, we will naturally be punished. Those catastrophic floods claimed countless lives, and due to the greenhouse effect, glaciers in Antarctica and the Arctic melted, resulting in rising water levels and seawater flooding coastal areas, which caused great economic losses. Isn't this the best proof?
My hometown Guangning relies on Zhuhai eco-tourism to develop its economy. Now the environment of some bamboo forests is so chaotic that people complain. Eco-tourism in Zhuhai is the foundation of our development in Guangning. When the roots are destroyed, how can we grow lush branches and leaves and produce beautiful flowers?
Let's be kind to human beings and nature! I wonder if you have read the article 100 things you can do to protect the environment. In fact, there are many things we can do. For example, plant a pot of flowers and a tree on Arbor Day; Protecting wild animals is the balance of ecology; Cherish water resources and don't dump garbage into the river; Being a little environmental guardian, using every green anniversary to publicize environmental awareness, so that green mountains are always there, green water is always flowing, and the soil is always fragrant ... these are all things we can do. Why don't we want to practice?
Now, the ecological environment of the earth is getting worse and worse, and the environmental alarm has sounded. Let's join the ranks of environmental protection, create a bright future in which man and nature live in harmony, and let man and nature live endlessly.

Recently, the school is still carrying out the investigation and implementation of the "plastic restriction order" to enhance everyone's awareness of environmental protection. The school also encourages students to learn environmental protection knowledge and introduce it to people they know and don't know. Our class has also carried out many volunteer activities with the theme of "protecting the environment, starting from me", such as: planting trees voluntarily in Xiaobi forest area to add a touch of green to the city; Clean up the city's "psoriasis" and bring new vitality to the city; Clean up community health, make the community look brand-new and let residents live in a clean environment. ...
After the launching ceremony, there will be a variety of cultural performances. What impressed me the most was the poem "The Earth-My Mother", which told us with deep affection about China people's bad behavior towards Mother Earth, and their final awakening and profound reflection. Finally, the reciter calls on us to protect Mother Earth, otherwise the last drop of water on the earth will be people's tears.
What attracts our attention most is the environmental protection public welfare works, environmental protection scientific and technological works, environmental protection handicraft works and environmental protection fashion show displayed in the four exhibition areas. These are environmental protection exhibits and model environmental protection creative works made by Hebei University of Science and Technology and our volunteers in No.40 Middle School. These handmade products are all made of plastic bottles, waste plates and other waste materials, and their rich imagination makes us gasp in admiration. The first thing that attracted me was the "non-electric car". The designer made the car with a toothpaste box and four small tires, and installed a magnet at the rear. The stick in his hand is also equipped with a magnet. Using the principle of like-sex repulsion, cars can run without batteries. Next is the "plastic bottle series" exhibits of college students. With a pair of dexterous hands, they can turn ordinary bottles into bundles of flowers, bracelets and storage boxes ... The most magical thing is the hourglass made of two plastic bottles, which is ingenious in conception and exquisite in production, which makes people full of praise. Another college student made a set of chess with bottle caps, and the chessboard was made of newspapers. It was really beautiful, economical and environmentally friendly. A big sister also made a backpack out of old jeans, and many people took pictures with their backpacks on their backs. The "big mouth sticky note box" is composed of old switch stickers. Put the post-it notes in, and the teeth will be formed, vivid and lifelike. All kinds of creative works broaden our horizons, increase our knowledge, stimulate our whimsy, and let me understand that technology is closely related to life. In fact, life is not a lack of beauty, but a lack of eyes that are good at discovering beauty. In life, we should pay attention to the things around us, be a conscientious person in life, and boldly use some wastes and environmental protection materials, maybe you will get unexpected results.
It is reported that these handmade products will be exhibited in 24 counties and cities, so that people can feel the environmental protection brought by science and technology, and it is sustainable environmental protection, so that citizens can protect our environment and care for our city in their daily lives.
At the end of the activity, we watched the dome movie "Deep Sea Oasis". There are beautiful natural landscapes and unique creatures here. They live in harmony and enjoy each other. This film introduced us to the habits of various creatures, enjoyed the unique natural scenery and met many biologists. Image maximum's Deep Sea Oasis makes people feel immersive. With the development of the plot, people are calm or excited, which makes people more deeply realize that people and nature, people and animals should live in harmony and become friends.
After the activity, I have a deeper understanding of the theme of this activity. In real life, we should closely combine environmental protection with science and technology, contribute to creating a healthy life, and strive to be an environmentally friendly, healthy and happy environmental volunteer.
