If it comes to an irreversible day, everything will go up in smoke. Don't study hard, swim in the ocean of knowledge. You don't have to work hard to pursue your ideals; There is no need for the state to introduce policies to improve people's livelihood, build a harmonious society and achieve all lofty goals, because the premise of all this is based on green. Without a green environment, the world is out of the question.
Don't do small good, don't do small evil ",start from me, start from small things, start from now, start from caring for the campus environment;" A piece of paper, we pick it up; A drop of water, we save; A pile of garbage, we clean; A flower, we cherish; A grass, we love it. We should protect the environment with our own practical actions, cultivate our green consciousness, and let green life inspire us to love life and study.
When the first ray of sunshine in the morning quietly falls on the campus, we are in the lush Woods, and the birds are sweet in our ears. what do you think? What do you think when the gray sky is filled with dust and black smoke, and the "buzz" and noisy noise of flies and mosquitoes fill your ears?
Green, the color of life; Green, the color of environmental protection. With green, there is fresh air; With green, there will be fragrant flowers; With green, there is a healthy life; With green, there will be a beautiful campus.
"The real test of our contribution to the environment is not words, but actions." I firmly believe that if we all have a sense of responsibility to protect the environment, starting from ourselves, starting from small things, and working together to protect our homeland, we will naturally give human beings due returns. 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.
In the vast universe, there is a crystal clear planet, full of life, flashing blue halo. This planet with a radius of only over 6,300 kilometers is our home-the earth.
But do you feel that she is old? Have you ever felt sorry for her? When she was polluted and traumatized, what would you think if I told you that there was no second planet for human activities within at least 40 trillion kilometers centered on the earth?
Will waste water, waste gas and waste residue be discharged at will for a little immediate benefit? Will there be reckless deforestation? What other rare animals will be brutally hunted, will they? ! We only have one life, and we only have one earth!
I once read that 1985, British scientists discovered an "ozone hole" the size of the United States over the Antarctic. Why is there an ozone hole? The ozone layer is in the stratosphere 20~25 kilometers away from the earth's surface. It is like the earth's natural "armor", which blocks a lot of ultraviolet radiation from the sun and protects everything on the earth from thriving. However, in recent years, when a large number of chemicals such as refrigerants, fire extinguishing agents and disinfectants are used, many harmful gases such as chlorofluorocarbons and chlorofluorocarbons are discharged into the atmosphere. Under the irradiation of ultraviolet rays, these gases will release chlorine atoms, and at the same time seize an oxygen atom in ozone, making ozone become pure oxygen, and the ozone layer is gradually destroyed. The natural armor of the earth is reduced, and the ultraviolet radiation of the sun takes advantage of it, which brings disaster to mankind. According to statistics, at present, the number of patients with skin cancer and cataract caused by ultraviolet radiation is increasing year by year, and the number of casualties is very alarming. In addition, the increase of ultraviolet radiation has also caused adverse consequences such as the decline of crop yield and the death of aquatic animals.
At the same time, I also learned that due to the sharp reduction of forest area on the earth (tropical rain forest is decreasing at a rate of 50 hectares per minute), the absorption capacity of carbon dioxide is reduced, resulting in about 50% of carbon dioxide discharged into the atmosphere by countless chimneys and other exhaust pipes on the earth staying in the atmosphere. In the past 200 years, the concentration of carbon dioxide in the atmosphere has increased by 25%. As a result, the earth's temperature has risen, leading to global climate anomalies, and the energy balance in the atmosphere is relatively fragile. As long as the temperature changes slightly, it may bring global disaster.
When the weak grass is trying to drill out the land with tenacious vitality, you jump over it. You deprived it of its young life for your own benefit. Would you like to?
The upcoming Chinese rose seems to be full of air and water, which makes it look so delicate. When the flowers bloom, you pick them mercilessly. Do you like it?
If we destroy the surrounding environment again for our own benefit, and let our mother earth have more dirty words, such as air pollution, water pollution, noise pollution and food pollution ..... They devour human life mercilessly like demons. It threatens the ecological balance, harms human health, restricts the sustainable development of economy and society, and puts our mother earth in trouble. But as long as we humans have the consciousness of protecting the environment and managing the environment according to law, the global village will become a beautiful paradise. Demons will never exist. 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.
Flowers and trees are gradually decreasing. Because flowers and trees can purify the air, but flowers and trees are gradually decreasing, and the air is polluted by viruses and bacteria. Because of breathing air, more and more people get sick, which brings great harm to people's health. If this goes on, it will pose a great threat to mankind, not to mention a harmonious society. Our earth is a beautiful planet. However, soil erosion and desertification continue to plague mankind. Are madly devouring the land on which people live. According to statistics, the deserts and wasteland on the earth are expanding at a rate of 27 million hectares per year, and the desertified land in China is also expanding at an area of 1.560 square kilometers per year. At present, China has 1.28 million square kilometers of potential desertification land, which is almost1.50 million square kilometers. Desertification has become the most serious problem endangering the global environment.
