The progress of society and the development of production have brought great convenience and happiness to our lives, improved the living environment of human beings and demonstrated the progress and development of human civilization. But on the other hand, we have also seen more cruel facts: the natural energy on the earth is decreasing day by day, the environment is being polluted day by day, the earth's ecology is being destroyed, and our physical and mental health is being greatly threatened. For the development of economy and social civilization, over-exploitation and industrial development have seriously damaged the earth's ecology for a long time, and our clean and beautiful global village has become more and more dirty and chaotic.
As far as electricity is concerned, at present, 60% of China's electricity consumption comes from thermal power generation, but thermal power generation has caused great damage to the ecological environment, seriously polluted the air and aggravated environmental damage; Industrial production leads to global warming, which changes the ecological environment of the earth and the living conditions of human beings. Chain pollution caused by production, such as solid waste pollution and water pollution, also seriously destroys the ecological balance and is extremely harmful to human body. Pollution of industrial production leads to the formation of acid rain, which seriously affects the development of agriculture and animal husbandry.
Although hydropower is clean, it also poses a threat to the human environment. Hydropower needs to build dams to intercept water sources, resulting in floods from time to time. Therefore, residents have to move, which not only causes people's anxiety, but also increases the economic burden of the country, intercepts water sources, destroys biodiversity and changes the ecology of rivers. It not only causes pollution, but also aggravates waste and destroys ecological balance, which is not conducive to the establishment of a green and sustainable society in China.
And air pollution caused by various reasons is also seriously affecting people's physical and mental health. According to the investigation, under the long-term action of low-concentration air pollutants, it can cause diseases such as upper respiratory tract inflammation, chronic bronchitis, bronchial asthma and emphysema. Moreover, air pollution is one of the important pathogenic factors of cardiovascular diseases such as coronary heart disease, arteriosclerosis and hypertension. The frequent occurrence of cancer, especially lung cancer, is closely related to air pollution.
In addition, air pollution will also reduce the immune function of human body and make people's resistance decline, thus inducing or aggravating the occurrence of many other diseases. Air pollution is also very harmful to agriculture, forestry and animal husbandry. Generally, the resistance of plants to sulfur dioxide is weak, and a small amount of sulfur dioxide gas can affect the growth function of plants, leading to defoliation or death. Around some nonferrous metal smelters or sulfuric acid plants, most trees died because of the long-term harm of sulfur dioxide gas. The fluorine-containing waste gas discharged from factories not only pollutes farmland and water sources, but also has great influence on animal husbandry.
In the 11th Five-Year Plan of China, energy conservation and environmental protection are placed in an important position, and building a conservation-oriented society and actively promoting circular economy are regarded as the important guiding principles for the preparation of the 11th Five-Year Plan. The 11th Five-Year Plan has been approved by the National People's Congress, with clear objectives: energy consumption per unit of GDP will be reduced by 20%, total pollutant discharge will be reduced by 10%, and forest coverage will be increased from 18.3% to 20%. This task is quite arduous.
There is only one earth for human beings, which is the foundation of human life and our common home. As a member of the global village, we have the responsibility and obligation to save energy, protect the environment, reduce pollution and defend our beautiful home.
Save energy, lift a finger; Environmental protection is necessary; Start with me, start with a little bit.
(1) In our daily work and life, each of us should actively enhance our awareness of crisis, economy and environmental protection, study hard in many ways, strengthen our knowledge of environmental protection and energy conservation, fully realize the crisis of resource shortage in China, understand the true significance of energy conservation and environmental protection to the country and individuals, and truly establish our awareness of energy conservation and environmental protection.
(2) Try to choose energy-saving lamps with high efficiency and environmental protection. Although the initial investment is high, in the long-term development, it not only saves the investment cost, but also contributes to the country's electricity saving. Because the fourth generation lighting source-the new LED green light source, under the same brightness, its power consumption is only110 of ordinary incandescent lamps, but its life is 50 times that of incandescent lamps.
(3) In daily life, try to use solar energy, which is a new green energy source, such as solar generator, solar cooker, solar lamp, solar cap, solar flashlight, solar dryer, solar water heater and floor heating system. Solar energy series environmental protection green products have obvious advantages of environmental protection, energy saving, safety, convenience, long service life, one-time investment and long-term benefit, which not only helps to save national energy, but also realizes green and sustainable development.
(4) First of all, we should always pay attention to saving electricity. Electricity is something we use every day or even every moment. The application and waste of electricity occupy the vast majority of our lives. Therefore, we should turn off the lights, try to turn off the lighting power supply when the light is sufficient, or reduce the number of lighting power supplies. We should not cherish and waste them just because they are national or collective. Each of us has a relationship with the country and the collective. To love yourself, we must love the collective, and sublimate the saving of electricity to the ideological realm of saving energy for the motherland and serving the people, so that people will not leave a ever-burning lamp when they leave.
(5) In our daily life or work, when the electrical appliances such as air conditioners or computers are out of service for more than 1 hour, we should turn them off normally and unplug the power supply. Because if you don't unplug it after turning it off, standby also consumes electricity. According to statistics, a computer mainframe consumes 5 watts, a monitor 5 watts, a speaker 10 watts, and a kitten (modem) 3 watts. Excluding printers, scanners and other infrequent devices, the total is 23 watts. Do nothing for at least 10 hour every night, so after 1 month, 7 kwh of electricity will be lost unconsciously. Another simple trick is to turn off the monitor when you leave. Because according to the calculation, the power consumption of the display accounts for about 1/3 of the whole computer system. Turning it off is equivalent to saving the power consumption of a 25-inch TV set. Save electricity, not only pay attention when using, but also avoid standby power consumption when not in use.
(6) Open the window for ventilation before using the air conditioner, and don't open the doors and windows casually after the air conditioner is turned on. The temperature in summer should be controlled at 26~28℃ as far as possible. According to the test, every time the temperature decreases by 2℃ during cooling and increases by 2℃ during heating, the power consumption will increase by 1 times on average. And pay attention to cleaning the filter frequently, which can also play a certain role in saving energy and reducing consumption.
(7) Experts pointed out that in terms of water resources wasted everywhere, using today's technology and methods, the water demand for agriculture can be reduced by 10% ~ 50%, for industry by 40%~90%, and for cities by 30%, which will not affect the economic level and quality of life at all. Therefore, we should also pay attention to saving water, turn off the faucet after use, repair the broken and leaking faucet in time, avoid excessive waste, use as much water as possible, always remind ourselves to save everything, and actively advocate and supervise people around us.
(8) Pay attention to care for forest resources, save paper, try to use double-sided copy paper, and use less disposable items, such as plastic bags, disposable chopsticks, lunch boxes, etc. Bring your own tableware, reduce white pollution, care for flowers and trees, protect national resources and save the existing energy of the earth.
(9) Make plans and statistics, use one thing as much as possible, learn to use old things skillfully, turn waste into treasure, and prolong the life of limited resources. Save the use of non-renewable energy, rationally apply renewable energy, improve your awareness of energy conservation and environmental protection in an all-round way, and form a good habit of thrift.
(10) In industrial development, we should improve the energy structure reasonably, use green and sustainable energy as much as possible, and choose energy-saving, environmental protection, safety and convenience. Individuals or families choose energy-saving and environmentally-friendly products, which not only saves their own expenses, but also makes more contributions to the country's environmental protection and energy-saving work.
(1 1) Friends who have a car should try not to warm the car in the original place when driving, do not suddenly brake, keep the speed, and repair the car in time to ensure that their exhaust emissions meet the national standards, maintain good performance, and reduce energy consumption and exhaust pollution.
(12) With regard to air pollution in China, other civil stoves in large and medium-sized cities and urban areas that have not been designated as areas where highly polluting fuels are prohibited will be switched to sulfur-fixed briquettes or other clean energy sources within a time limit. Therefore, each of us should also pay attention not to burn polluting items casually.
(13) Garbage shall be treated in a unified way according to national regulations, and attention shall be paid to classification. In our life, we can see that a lot of garbage is burned on the spot, because many items in the garbage will produce toxic gases after burning, such as the pungent smell of plastic items when burning, which not only affects our normal life, but also harms our health. Therefore, we should not only stop burning garbage on the spot, but also correct and persuade others to do so in time.
(14) Everyone tries their best to avoid noise pollution, so as not to make noise or whistle in the city. In order to avoid noise as much as possible, * * * Qi Xin works together to create a quiet and comfortable living and working environment. The noise level is 30 ~ 40 decibels, which belongs to a relatively quiet normal environment; More than 50 decibels will affect sleep and rest. Due to lack of rest, fatigue cannot be eliminated, and normal physiological functions will be affected to some extent; Conversation interference above 70 decibels causes distraction, inattention, affecting work efficiency and even accidents; Working or living in a noise environment above 90 decibels for a long time will seriously affect hearing and lead to other diseases.
(15) Do not discharge untreated industrial or domestic sewage at will. The discharge and treatment of sewage shall conform to the regulations of national industry or family community. In all aspects of our lives, water can be used at any time. Whether water is clean or not is directly related to human health. After water pollution, pollutants enter the human body through drinking water or food chain, causing acute or chronic poisoning. Arsenic, chromium, ammonium, etc. It can also induce cancer. Water polluted by parasites, viruses or other pathogenic bacteria will cause many infectious diseases and parasitic diseases. So always pay attention to your every move. Maybe our carelessness today will cause harm tomorrow.
(16) Develop a good habit of not spitting and littering. Because dust pollutants will be inhaled with the air after decomposition, it is very harmful to human body. In addition, attention should be paid to recycling waste batteries and paper to minimize pollution.
(17) Please choose environmentally friendly building materials to decorate the living room. Many people will feel headache and nausea after living in a newly renovated house, which is caused by pollution in the decoration process (such as using materials containing benzene and other harmful substances exceeding the standard). Therefore, the decoration should try to use environmentally friendly materials.
(18) Refused to use wildlife products. If you don't wear rare animal fur clothing, try to wear natural fabrics; Refuse to eat wild animals; Traveling in the wild, not poaching wild animals and so on. Maintain the ecological balance of the earth and protect the environment.
(19) "It is everyone's responsibility to save energy and protect the environment." This is not only a slogan, but also to be put into practice. Everyone should start from himself, from now on, from the dribs and drabs of life.
(20) Actively publicize and strengthen the awareness of energy conservation and environmental protection, actively strengthen the supervision of yourself and others, and strive to set a good example of energy conservation and environmental protection for people around you in daily practice.
A beautiful earth, a peaceful life and a clean environment are the necessary conditions for us to build a civilized and well-off society and a powerful guarantee for us to create a better life. Protecting the environment is everyone's responsibility.
Try to avoid water pollution, air pollution, solid waste pollution and noise pollution. In daily life, strive to do a good job in environmental protection; Pay attention to saving water, electricity, food and everything in life, and fully realize the true significance of energy saving and consumption reduction.
Save the environment, you, me and him, and benefit millions of children. Today, your efforts will be the glory of the motherland tomorrow. Sustainable development is a long-term strategic goal, which requires the joint efforts of generations of human beings. Now is the transition period from traditional growth to sustainable development, so the efforts of recent generations are the key to success. Each of us must unswervingly follow the road of sustainable development from now on. Everyone should actively respond to the call of the country, strive to achieve green and sustainable development, and enjoy white clouds and blue sky.
Please respond positively to the initiative, and from now on, start from bit by bit and strive to "do more for energy conservation and environmental protection".
