Primary school students are diligent and wasteful.

First, it is urgent to save electricity.

A university journalism student made a survey on campus garbage. I cann't finish taking pictures

According to statistics, the school's annual electricity waste is 133682 kWh, which is enough for an ordinary family to use for 58 years. Colleges and universities are the most populous units. As such a huge unit, the utilization rate of resources in all aspects is quite high, especially the electricity consumption, which is quite amazing. Therefore, colleges and universities should incorporate electricity conservation into long-term development planning. The leading organizations and relevant departments of the school should first enhance the awareness of saving electricity, understand various ways and means of saving electricity from all aspects, and strive to make the right choice for the long-term development of the school. Energy saving will not happen overnight. We should look at the problem of saving electricity in schools from the perspective of long-term development.

As an educational base for cultivating higher talents, colleges and universities should comprehensively cultivate students' quality. Saving energy and reducing consumption is a real example of education.

First, the choice of electricity.

At present, although commercial electricity is not as expensive as before, it is still unbearable for large electricity users. Compared with various power consumption modes, solar power generation system has considerable advantages in systems with huge power consumption such as universities and factories.

Take the solar lamp as an example. First of all, solar lamps and lanterns use solar photoelectric conversion to provide electricity, which is inexhaustible. Secondly, solar energy is green energy, environmental protection and pollution-free, which is in line with the development theme of promoting green environmental protection in China at this stage. Third, the electricity generated by solar energy is low-voltage direct current, and there will be no safety accidents such as electric shock and fire. Fourthly, the installation of solar energy is convenient and simple, and it can be used spontaneously on site without additional wires, thus avoiding the unsafe and inconvenient factors caused by construction. Fifth, one-time investment is equivalent to long-term investment in alternating current, which will benefit for a long time. Generally speaking, solar power generation can be guaranteed for 25 years, which reduces labor costs, maintenance costs and expensive electricity bills compared with alternating current.

From the long-term development of colleges and universities, solar energy entering colleges and universities is the best way to save electricity. First of all, it can be changed from street lamps, and all school street lamps can be changed into solar street lamps. Solar street lamp has high luminous efficiency, high brightness, long service life, energy saving, economy, environmental protection and practicality. Charging can be used for 3-7 days a day, which solves the problem of using electricity in rainy days. You only need to invest the cost of solar street lamps once, and you can sit back and relax for 25 years. Besides, we can try to build a solar power station. According to the design, the generated electricity can be used for normal lighting and daily use in the whole school.

B. light source selection.

All light sources in the school can be changed into high-efficiency LED green light sources, which can effectively save a lot of power resources. LED light source is a light-emitting device made of semiconductor chips, which has obvious advantages such as high luminous efficiency, low power consumption, long service life, low working temperature, strong safety and reliability, fast response speed and environmental protection. Under the same brightness test, the power consumption is only one tenth of that of incandescent lamps, but the service life is 50 times that of incandescent lamps and 20 times that of fluorescent lamps.

C. General mobilization of teachers and students of the whole school.

To carry out comprehensive energy-saving education, every student and teacher should start from themselves and start from the small things around them to save every kilowatt hour: turn off the lights when people leave, turn off the electricity in time and cut off the power supply. Incorporating electricity saving into the comprehensive quality assessment of students and teachers will fundamentally change the situation of students and teachers wasting electricity. Call on all teachers and students to mobilize and make contributions to saving electricity and building a green and sustainable society.

Second, save water and prevent water pollution, starting from bit by bit.

In teaching buildings and dormitory buildings, you can often see thin water. According to our investigation, if a teaching building wastes an average of 2945.2 tons of water, according to this calculation, if there are 13 teaching buildings in the main campus, it wastes 38287.5 tons of water; The dormitory wastes an average of 57 1.7 tons of water. If there are 29 dormitory buildings in the main campus, the total waste is 16578.7 tons. According to the calculation of 6 yuan money for one ton of water, the school wastes as much as 320,000 yuan in water fee a year. In order to save water resources and prevent pollution, we should start from every point of life:

1. Turn off the tap when using to avoid running water.

2. Maintain the faucet in time to avoid wasting water resources due to equipment damage.

3, one water is multi-purpose, and the toilet is washed with water for washing clothes; Water the flowers with washing water, etc.

4. Use phosphorus-free washing powder for washing clothes to reduce pollution.

5. Leave the rinsed water to the next batch of washing water.

6. Use detergent with caution and use soap as much as possible to avoid water pollution.

According to statistics, sanitary water accounts for about 70% of everyone's water consumption. Schools can replace the water equipment in toilets and boiling water rooms with water-saving ones.

8. Turn the faucet from full to 1/4. By shortening the time of opening and closing the faucet, the loss of water is reduced.

9. The school toilet can be changed into a low-flow sprinkler or a slow-flow device can be installed on the original sprinkler, which can effectively ensure the water demand and reduce the water flow.

Third, save paper and protect forest resources.

Nowadays, the amount of paper wasted by college students is staggering. In the process of looking for a job, a lot of paper is produced.

It has become a thick resume for job hunting. According to statistics, cutting down a five-year-old poplar tree can only make enough paper for three students to apply for jobs. In addition, only one side of paper is used now, because there is a little scratch on one side, a lot of paper will be thrown into the wastebasket; Now students' homework and graduation thesis need to be printed, and they are all one-sided. If one page is crooked or slightly unclear, they need to be reprinted, so the paper is wasted twice or more. We can save paper in the following ways:

1, advocating multi-purpose, you can accumulate single-sided paper with a little bit of wrong printing or writing, bind it into a book, and use it as a draft;

2. When the teacher assigns homework, if it can be expressed in documents, try not to print it, and promote the wide use of electronic documents;

3, waste paper can be classified, or used for secondary utilization, or sold to reduce waste;

Save every grain and form a good habit of thrift.

College students' self-examination found that the campus wasted an amazing amount of food, and the canteen dumped an acre of food a week. Faced with this shocking figure, everyone needs to ask himself: "Why waste it?" Because you can do whatever you want with money? The money is yours, but the resources belong to everyone! No one has the right to waste! When you pour food into the trash can, it constitutes disrespect for other people's labor and a waste of parents' blood and sweat.

In just one week, the rice equivalent to an acre of land was dumped, indicating that waste is widespread. However, what is more terrible than the phenomenon is the indifference of students and the extreme lack of awareness of saving. As contemporary college students, as the leading force of the future development of the motherland, high-quality talents who have received the education of "weeding at noon, sweating in the fields, and hard work for every meal" are so ignorant and numb!

First of all, schools need to formulate practical rules and regulations to save resources, put savings into action, and even incorporate them into students' ideological and moral evaluation.

Secondly, the school can organize a special "saving group" to carry out strong graphic publicity or cultural performances on campus waste and saving.

Thirdly, all kinds of vivid and interesting propaganda slogans and related slogans about "saving is a virtue, wasting is a shame" can be hung in the canteen to remind students and teachers who come to eat at all times that the fruits of labor cannot be wasted.

Fourth, as a college student, don't treat saving money as a trivial matter. Zhuge Liang said, "Be quiet to cultivate one's morality, and be frugal to cultivate one's morality." Diligence is a necessary condition for one's self-cultivation. This is especially true for college students.

Finally, commend and reward effective classes and individuals, and call on all teachers and students to establish a sense of thrift and develop a good habit of thrift.

Economy has always been the traditional virtue of the Chinese nation. Saving out of poverty is instinct; Saving for habit formation is a kind of perseverance; Saving for the formation of culture is a virtue; Saving for building civilization is a kind of character; Saving for social development is an unshirkable responsibility!

Five, put an end to the use of disposable items, reduce white pollution.

Disposable articles bring temporary convenience to people, but bring disaster to the ecological environment; They have accelerated the depletion of the earth's resources and brought environmental pollution to the earth. Schools can take the following measures to eliminate disposable articles and reduce white pollution:

1. The use of plastic bags should be strictly controlled in supermarkets or shopping malls in schools. White pollution can be reduced to some extent by not providing plastic bags or providing plastic bags for a fee.

2. When dining in the canteen, you must bring your own tableware. It is forbidden to provide plastic bags, disposable chopsticks, lunch boxes, etc. in the canteen. To diners.

3. Now, walkman, CD, MP3, Wenquxing, etc. It has become a necessity for college students, and the battery consumption is also very high. Usually, students throw waste batteries directly into the trash can, sometimes toxic liquid leaks, and it also causes potential pollution to the environment. Rechargeable batteries can be used instead of ordinary batteries, which can easily reduce the pollution caused by batteries.

4. Use handkerchiefs instead of paper towels, porcelain cups and glasses instead of paper cups and plastic cups, and mechanical pencil instead of wooden pencils.

5, each class in the class to establish a small garbage point, garbage according to paper, plastic, metal (such as cans, etc.) classification. ), batteries, and other five categories of classified collections. Because there is a lot of paper and plastic, it can be cleaned once a day. In addition, considering the harm of batteries to the environment, students are advised to recycle waste batteries in a unified way.

6. The school has set up several large trash cans to recycle the garbage in each class, and set up more small trash cans on campus. The school is responsible for contacting the social recycling unit and sending out the recycled garbage in time.

7. Schools should establish a grading system to encourage classes to do a good job in garbage collection. The recovered income can also be returned to each class for use.

It should be noted that in order to truly and fundamentally eliminate white pollution on campus, students must

In order to establish the concept of environmental protection, it is suggested that schools strengthen environmental education, such as collecting environmental protection signs, holding environmental protection writing competitions, holding environmental protection singing competitions and other activities, so as to make environmental protection awareness deeply rooted in the hearts of the people.

Strengthening environmental education for students is also to promote environmental knowledge to the whole society, so it is suggested that schools carry out public welfare activities for the society in various ways.

Multi-purpose, reducing the waste of daily necessities.

With the improvement of living standards, more and more college students keep up with the new trends and buy whatever is popular. In fact, many things are not unusable, but outdated. If you don't want them, you can change them In their view, this matter is too small to think so much.

Repeated use of things should be a new campus atmosphere and a new pursuit of life. You can refer to the following methods:

1, avoid impulse shopping. Before shopping, ask yourself a few questions: is this item a luxury? Do I have something else to replace this? Will this item be replaced by another more beautiful one soon? If you buy it, do you want to dispose of another usable item? If the answers are all yes, then bear it and don't buy it.

2, do a good job in planning statistics. Always check your belongings, use what you can, and decorate with some tips to make yourself more beautiful; If it is not damaged but really useless, it can be given away or damaged and sent to the disaster area; We can only get rid of the irreparable.

3. Batteries are consumables, so it is normal to replace them when there is no electricity. However, if the power consumption of items that need batteries is arranged from high to low, the batteries will be used layer by layer to make full use of the batteries, and then unified environmental protection treatment will be the best measure for both parties.

Everything is brand-new, only one rags. You can embroider a flower or a unique pattern in the damaged place.

5. Beautiful clothes that you don't wear can be converted into small handbags or other decorations, and you can make them yourself, which saves items and is meaningful.

7. Reduce noise pollution and maintain a quiet learning environment.

Keeping a quiet atmosphere on campus is a good guarantee for students' study. Noise pollution is very harmful and is an invisible "killer". Campus noise brings many adverse effects to teachers and students: teachers and students can't live, work, study and sleep normally; Teachers and students can't adjust their psychological state normally, and they are anxious, fidgety, angry and even irrational. Noise damages people's hearing, and it can also cause various diseases, such as heart disease and high blood pressure. In particular, our classmates are in the period of physical and intellectual development, and noise pollution will make students' hearing decline, inattention, fatigue easily, affect their study and do great harm to their physical and mental health.

In view of campus noise pollution, the following suggestions are put forward:

1. You can read silently and read aloud in the morning class to prevent noise from affecting other students.

Students can speak loudly in class. When discussing in groups or in the whole class, talk as quietly as possible, and don't make too much noise.

Don't play in the classroom between classes, and don't chase and fight in the corridors and stairs. The school playground is very open and the sound is easy to spread. Remind students to go to the playground, football field and basketball court as much as possible for various beneficial activities.

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 issued 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.

Is that enough?
