In order to survive, it is absolutely necessary for human beings to develop and utilize resources and energy, but all development and utilization should be considered comprehensively and scientifically from the whole nature, especially the ecosystem of the earth's environment, that is, the so-called biosphere balance, so as to realize the coordination between man and nature on the basis of protecting the natural environment and maintaining ecological diversity.
At present, we should not only strengthen and expand those ecosystems with primitive characteristics, that is, those ecosystems that are less affected by human beings, but also maintain their original natural characteristics and balance various elements in the ecosystem through artificial protection and reconstruction, and attach importance to the valuable experience gained by human beings in understanding the toxicity of chemical substances. For various comparative substances, from production to waste, we should consider a safety measure to prevent environmental pollution, and also seek pollution-free production methods to produce non-toxic chemical products. Obviously, this is a higher and more arduous task for chemists.
Article 26 of the Constitution of China clearly states: "The state protects and improves the living environment, prevents pollution and other public hazards, and organizes and encourages afforestation to protect trees." In this way, under the attention and leadership of the Party and the state, we should vigorously publicize and popularize the knowledge of "environmental protection", and Qi Xin should work together to create a balanced, beautiful, pollution-free and pollution-free environment.
How to protect the earth environment
Hello, Grandpa Earth, we are compassionate and caring pupils. I am sad to see what human beings have done on TV. You have always cared for us so much that the outside world can't use it, but people still overdo it and use it to hurt you. Although I can't make a great contribution to you, we can start from ourselves and call on our classmates to protect you together. Please rest assured. Here are some suggestions to protect you. I wonder if it is possible to:
1, no spitting.
2. Protect life on earth
3. Turn off the faucet in time after using water.
4. All kinds of flowers and trees make you more beautiful.
5. Protecting the ozone layer
6. Don't throw rubbish casually
7. Garbage classification
8. Recycle waste batteries
9. Try not to smoke black smoke.
10, don't waste paper.
You know what, my friend? So far, in the vast universe, except our earth, scientists have not found life on the second planet, which shows how precious life is.
Yes, life is indeed precious to human beings, but human life is also fragile, and any little injury may cause deformity and termination of life. Therefore, the continuation of life requires a lot of people's Qi Xin to work together, cherish and care, and more importantly, to ensure safety. However, the world we live in cannot be absolutely safe. Environmental pollution, earthquakes, floods, fires, and injuries caused by human factors, etc., so many unsafe factors are constantly eroding and threatening people's lives.
Safety is very important for everyone, especially for us children who haven't grown up. However, around us, there are always so many children who don't pay attention to safety, don't cherish life, and turn a deaf ear to teachers' teaching and parents' advice. As a result, they were not only hurt, but also delayed their studies, and some even caused disabilities and life-threatening. For example, some children don't obey the traffic rules, don't listen to the traffic police, and cross the road to run a red light; Some students like to chase and fight on the stairs, deliberately squeezing around on the stairs; Some children like to play with sharp scissors and knives; Other children don't go home after school, like to stay in public places, and even eat unclean food in food stalls ... these are unsafe behaviors, causing different degrees of harm. Last year alone, I heard several such things. Some schools have no order after class, hurting seven students at a time; Some children were injured by firecrackers; Other children hurt their legs and feet. Last year, three students in Shuangzhuang were poisoned at the same time because they bought food from illegal vendors and ate rat poison by mistake. If it hadn't been found early and rescued in time, they almost lost their lives. Just a few days before the May Day holiday this year, a little girl who was about to graduate from junior high school unfortunately fell from the stands more than two meters high and broke her head during extracurricular activities. She lost consciousness and almost lost her heartbeat and breathing. Although rescued by medical staff, she is still not out of danger. A lively and lovely little girl suddenly turned into a vegetable who stayed for a while, a budding flower withered like this, and a happy family was ruined like this. How can I not make people sad? ...
As can be seen from the above example, there are too many unsafe factors around us! How important safety is to our study and life! Each of us should master safety knowledge and enhance safety awareness and self-protection awareness. Master the method of safe self-rescue, and learn to prevent and deal with all kinds of catastrophic accidents. Only by putting safety first can we stay away from danger and grow healthily. As for how to be safe, I don't think I need to introduce them one by one. There is too much safety knowledge in life, which can be seen everywhere in books, newspapers and TV. As long as you want to learn, as long as you pay attention, as long as you always think about safety, pretend to be safe psychologically and pay attention to safety in action, safety will always accompany you.
Dear child, maybe you have many dreams, maybe you have great ambitions, but you know what? Life is the foundation of all life. There is no health without life, and there is nothing without health. Without security, any ideal may become a fantasy. My mother always said that health is "1", and many zeros can be added after it through study and hard work, but if there is no life and no health, there is nothing, nothing. But precious life is only once for everyone. Without safe water, flower of life can't be open and the tree of life can't be evergreen. We need everyone's careful care, the concerted efforts of all mankind's Qi Xin, and every child needs to start from me. I believe that as long as every child can put safety first and grasp the golden key of safety, we can have safety, stay away from danger and grow up healthily.
Students, let's work together, shoulder to shoulder, and move towards a better tomorrow together. May the water of safety flow forever, may the tree of life be evergreen, and may every child grow up happily and healthily!
