As early as 1977, the United Nations held a conference on water resources, which issued a solemn warning to the whole world: water will soon become a profound social crisis, and the next crisis after the oil crisis will be water. The era of regarding water as inexhaustible has passed, and the era of regarding water as a valuable resource has arrived. China ranks only 84th in the world in per capita possession, and is one of 13 water-poor countries in the world. 300 cities in China are short of water, nearly 50 cities are seriously short of water, and 14 coastal cities are short of water.
China is also facing a serious water crisis, and many places are short of water. Please listen to these figures: 1988 In summer, Wuhan residents forcibly opened 50 fire hydrants to get water. 1989, Xi' an, once known as the "Eight Rivers in Chang 'an", had a water-cut area of 27 square kilometers. According to the relevant water resources report, the groundwater level in Kunming, Yunnan Province, which is relatively rich in water resources, is declining at an average annual rate of 0.1m ~ 0.31m. Can't these terrible facts and amazing figures attract our attention?
However, there are still various phenomena of wasting resources around us. On one occasion, several big brothers in our school turned on the tap to let students wash their hands and fought with water. Seeing this, I quickly went forward and turned off the tap. However, several brothers pushed me away and said, "It's none of your business, go away!" " . According to my observation, a similar phenomenon occurs in our life: in broad daylight, the office lights are on; In cooler autumn, air conditioners and fans are turning; Water from public taps often drips. When will these phenomena disappear? Do we have to wait until water resources are scarce and exhausted before we come back to talk about saving?
"Saving water" is not to limit people's use of water, let alone to prevent it. In fact, saving water is to make people use water reasonably and efficiently. Saving water does not affect our quality of life. Everyone has the obligation to cherish resources and correct others' waste of water resources. The view that "as long as I pay the water fee, I can squander it at will, and wasting water is my own business, and others can't control it" is wrong, and the view that "water is only 70 cents, which is very cheap, and it doesn't matter if it is used too much" is even more harmful. Saving water is the responsibility of every citizen.
China's water law points out that water resources are owned by the state, that is, by the whole people. All countries in the world also stipulate that water is public property. Therefore, everyone should have a sense of public water. Power resources are also very precious, which embodies the efforts of many people. Everyone should cherish and save water and oppose water pollution and waste.
"Look at the former sages and their families, they became thrifty and were defeated by luxury." Running a school with diligence and thrift is a public morality and a virtue.
Students, uncles and aunts, let's take action. Let's cherish resources and strive to build a conservation-oriented society.
In terms of energy waste, families also account for a considerable proportion. Multiple TVs are turned on at the same time; Multiple computers are used at the same time; Don't cut off the power supply when the TV is not watching, and stay in standby state for a long time; Dozens of incandescent lamps with hundreds of watts are turned on at the same time; When the sensor of the voice control light is broken, the light will be on day and night; The water dispenser operates 24 hours a day; Some electric heating households don't blink when they use several kilowatts of electric stoves in winter; Turn on the tap and let it run for a few minutes. Hot water is coming out, just wash it slowly ... every bit is insignificant. But it's like this, and the energy waste in residential areas is quite prominent. Check our behavior, the common "unconscious waste", there is too much precious energy wasted in family life. Habit becomes nature, and many wasteful phenomena are cultivated by people for a long time, so there is not much consideration for saving household energy. However, in real life, it is actually very simple for us to get rid of those "habits" that are wasted at will, and we only need to lift a finger. A good living and working environment is the condition for our human survival, and protecting the environment means protecting ourselves. Facing the reality of the deterioration of the earth's ecological environment and the shortage of resources, we should clearly realize that saving the earth, protecting the environment and saving energy are our common responsibilities. Family energy conservation and environmental protection are closely related to our lives and are easy to carry out. Doing a good job in family energy conservation and environmental protection not only saves resources, but also saves some expenses for families, killing two birds with one stone. From this, we propose: first, start with household electricity, save every kilowatt hour and put an end to household appliance pollution. Every family should strive to do the following: a, replace incandescent lamps with fourth-generation LED green light sources. Under the same brightness, its power consumption is only one tenth of that of incandescent lamp, but its life span is 50 times that of incandescent lamp. B chlorine-free green household appliances and solar household appliances should be selected, such as solar generators, solar cookers, solar lamps, solar caps, solar flashlights, solar dryers, solar water heaters and floor heating systems. , not only energy saving and environmental protection, but also safe and convenient, which not only contributes to the national energy saving and environmental protection work, but also leads the new trend of family green life. C. when purchasing air conditioners, consider the number of people who are most suitable for the room size. And the air conditioning temperature is set at 26-28℃ in summer. D, the food stored in the refrigerator should not be too full, and there should be a gap of more than 100mm between the food in the refrigerator and between the food and the box wall. This can save energy by 20% every day than sticking to the wall. E. the power consumption of the washing machine depends on the use time. Generally, it takes 3 ~ 4 minutes to wash synthetic fibers and wool fabrics, 6 ~ 8 minutes to wash cotton and linen fabrics, and 10 ~ 12 minutes to wash extremely dirty clothes. F, don't turn on the TV very bright, and don't turn it too loud, because every time you increase the audio power of 1 watt, you will increase the electrical power consumption of 3 ~ 4 watts. G, it is best to use an electric cooker to wash rice in advance and cook with warm water or hot water, which can save electricity by 30%. H. Unplug the electric cooker immediately after use. When the temperature in the pot drops below 70 degrees Celsius, it will automatically be electrified intermittently, which not only consumes electricity, but also shortens the service life. First, as long as a special energy-saving film is attached to the ordinary glass window, the indoor temperature will drop by at least 3℃. If the sun is stronger, the temperature difference will be further widened and the energy saving effect will be more obvious. According to reports, after adopting this energy-saving film, it can not only filter ultraviolet rays, but also save energy by 30%, with a service life of 20 years.
My friend told me something after returning from a trip to America, which left a deep impression on me. There, his camera battery died, so he went into a shopping mall and wanted to buy two No.5 batteries. He pointed to the fifth battery in the counter and told the salesgirl to buy two. The salesgirl turned around and took out a battery and recommended him to buy it, saying it was cheaper. He compared the prices and found that the latter was not much cheaper than the former, and it was only a dime when converted into RMB. He said it doesn't matter, it's not bad. Unexpectedly, the salesgirl said with a smile, it's not just a matter of saving money. If it's packed in two pieces, throw one box less and it's environmentally friendly! It seems counterintuitive for a salesman to take the initiative to let customers buy cheap ones and spend less money. First, it aroused the curiosity of this friend, and then, the mystery was solved. What the salesgirl wants is to throw one less box. The friend sighed: "Look at people, not only thinking about saving, but also thinking about environmental protection. Environmental awareness is really strong! " This reminds me of an activity organized by a large foreign company I attended not long ago. The business cards issued by this company to customers are uniformly printed, which are simple, dark yellow and a little thick. Later, I learned that I used recycled paper. I don't think this big company will care about this little money for just a business card. In doing so, they are silently advocating environmental protection, at least objectively, they have indeed received the dual effects of saving and environmental protection. Look at our own business cards again. I often receive business cards, except this time, I have never seen them made of recycled paper. Every year, it is inevitable to throw away some business cards for various reasons, some of which are excellent in paper and beautifully printed, and some are folded by 20% or more. It is really painful to throw away such a business card. If you don't throw it away, there will be no place to put it. I think many people feel the same way. Later, I tried not to use business cards or use them less, and only wrote my own contact information. Judging from the above two small things, saving is not just a matter of saving a few dollars. In many cases, saving means reducing the consumption of goods and reducing the pressure on the environment. In a word, saving is environmental protection. In that case, no matter how much money you have, no matter how much money you have, you don't care about money, but please note: you have no right to waste or destroy the environment! Recently, the media is promoting a view that spending money has no right to waste. I totally agree. Look around us, there are too many things that don't pay attention to saving and destroy environmental protection at the same time. Disposable chopsticks, disposable paper cups, plastic bags, over packaging, office paper envelopes, stationery, etc. The waste of these items is almost numb, who will care about these? It seems that we not only have no awareness of saving, but also lack the concept that "saving is environmental protection". Imagine that if all our citizens have a strong sense of environmental protection and are so serious as that salesgirl, if we can think about conservation and environmental protection while enjoying all the conveniences and comforts brought by modern civilization, then building a conservation-oriented society and realizing sustainable development will accelerate to become a reality.
As we all know, the excessive demands of human beings on nature have led to the merciless revenge of nature: hurricanes, rainstorms, blizzards, floods, droughts, insect pests, extreme heat, forest fires, earthquakes and other disasters have come unexpectedly. It is estimated that by 2025, the number of migrants caused by drought and other reasons in the world will reach 654.38 billion.
The painful ecological lessons have attracted the attention of all countries and mankind. When the IOC evaluation team visited the bidding cities, it listed improving the ecological environment as one of the important contents. Our country attaches great importance to environmental protection workbench, promulgates many policies and regulations on environmental protection, and carries out many environmental protection work and activities.
At the same time, China also attaches great importance to environmental protection education, and "green school creation activity" is one of the important contents. Our school has made great achievements in environmental protection and greening.
We often see many students picking up peels and scraps of paper in every corner of the campus; Protect the beautiful campus environment with your own hands. However, we still have some shortcomings: some people still throw paper scraps and food bag waste; Others trample on the lawn; In the green belt of the school, deep footprints are found from time to time, and some places even become paths.
Students, we are the masters of 2 1 century, and environmental awareness is an important symbol of modern people. We should earnestly establish a sense of responsibility for the times. Look at the world, pay attention to the side, based on the campus. Bend down and pick up scraps of paper. First of all, don't throw it around. Take a few more steps, don't cross the green belt and trample on it. "Don't do it for the small good, don't do it for the small evil", start from me, start from childhood, start from the side, and start from now. Protect Mother Earth and purify the green campus. Make our campus more beautiful!
Suggestions on protecting the campus environment
Dear teachers and students:
Hello!
Another dazzling spring is coming. In spring, vegetation is thriving and full of vitality. In this day of returning to the earth in spring, we have ushered in the annual Arbor Day.
The earth is the only place where human beings live. If human beings want to live and work in peace and contentment on the earth, they must love the earth and nature. We should cherish every green leaf, every grass and flower. Take care of the earth, protect the environment and green the campus, so that green life can inspire us to love life, study and cherish youth. Therefore, as a member of the third middle school of Tangqin Town, a green school in the whole autonomous region, we solemnly propose to the teachers and students of the whole school:
Let's * * * hand in hand, let the seeds bloom like flowers, let the seedlings be shaded by trees, and put our practical actions into the "planting trees, loving green and protecting green" activity in March, starting from ourselves, to prove to the whole society that we are a high-quality generation, and we really know how to cherish green!
People grow in nature, and green is the color of nature. How precious green is! It is life, hope and happiness. Let's take action and make our own contribution to the creation of green.
