Environmental protection-our responsibility

I don't know if you have noticed a text-"Investigation Report on National Environmental Literacy in China". The contents of the report are as follows: the good index ranks first in the world; The scientific literacy index is medium; There is a big gap between environmental literacy and developed countries: 30 years from developed countries in northern Europe; 20 years behind the environmental protection developing countries such as the United States; Japan/Korea/Singapore and other advanced Asian countries have a gap of 20 years in environmental protection; The difference between Africa and Latin America is 10 year. The country is comparable to developed countries in environmental protection concepts and policies: citizens' ability to implement national environmental protection concepts and policies cannot be docked;

Environmental blindness is the bottle diameter to solve the development of environmental protection because of the large proportion of population; Elite group ranks first in the world in environmental protection theory/is overhead by hidden rules in environmental protection practice; Develop first, then govern (cadre group/hidden rule) is deeply rooted in the current national life and production concept; Citizens who know a little about environmental protection, can speak and resolutely do nothing are in the period of environmental fatigue; Almost everyone thinks that environmental NGOs have problems/don't understand/can't solve the problems of environmental education and publicity; Enterprises are interested in environmental protection activities organized by the state, give moral support to long-term environmental protection public welfare propaganda, and never participate; Citizens hold a wait-and-see attitude towards environmental protection workers, don't understand them and show disrespect for hidden rules (because they are troublemakers/don't make money), but the news and state media support them morally;

Citizens with environmental literacy account for less than 5% of the total population; The groups with environmental literacy are: a few elites with overseas study background, high-level think tanks, a few white-collar workers, and people whose direct environmental protection interests have been violated; Most people who exercise outdoors.

The reference solutions given by the state are as follows: 1 The education system urgently needs to improve environmental literacy education; The means of national environmental literacy education need to be strengthened and practiced urgently; 3. Vigorously advocate outdoor activities in which people walk into nature and get close to nature; 4. Strengthen the enforcement of existing environmental laws and regulations; Environmental blind re-education should be brought into national ideology.

Today, various policies and measures for environmental protection and energy conservation have become the development trend of civilized life that we are familiar with. However, do we really know them well? Have we really done it in our daily work and life? Is it that when you listen, you are still focused, and then you talk about happy words, so you don't concentrate when you do it? Energy conservation and environmental protection can not be achieved by shouting a few more slogans. It needs us to really improve from real life, start from everything around us and practice.

As every family, it plays an irreplaceable role in promoting social development and human progress, and is the main strength pillar of our social development. Therefore, we should improve the comprehensive quality of families, truly understand the practical significance and great role of energy conservation and environmental protection, organize each family member, hold them together firmly, start to understand and improve from all aspects of life, and implement the theme of energy conservation and environmental protection.

To advocate energy conservation and environmental protection, we must first reduce our understanding of where energy consumption is in daily life. Where is the pollution? Aiming at the main problems, improve the efficiency of energy saving and environmental protection. So which is more serious, family pollution or social pollution?

Recent research shows that the pollution caused by social industrial production only accounts for 4 1% of the pollution sources, while the pollution caused by modern families accounts for 59%. Compared with society, although family is only a cell of society, it is relatively serious in terms of pollution. Hundreds of toxic and harmful substances have been detected, and there are more than ten common ones. There is a set of statistical data that can further prove the harmfulness of household pollution: that is, a household produces 1.8 kg of garbage every day on average, throwing away five non-degradable plastic bags and two or three disposable lunch boxes; A family produces an average of 200 kilograms of wastewater every day because of washing hair, bathing and washing clothes. A family uses an average of 20 grams of chemicals every day. These pollutants and domestic wastewater flowing into rivers have been polluting our land, rivers and oceans.

According to media reports, in an indoor pollution survey of more than 2,000 household samples, the results show that more than 50% of households have indoor pollution, and the "culprit" is household appliances. What is even more worrying is that most of the families surveyed are not aware of the pollution problem of household appliances. At present, common pollution caused by household appliances includes bacterial pollution, radiation pollution and noise pollution, which are harmful to health and even endanger people's lives.

Seeing this set of data can't help but surprise us. All along, we have to point the finger at industrial production. As we all know, the biggest pollution source is ourselves, that is, every family. We usually don't pay attention to the consequences of environmental protection and energy saving. In the final analysis, what hurts the most is ourselves, our beautiful home, a clean and peaceful global village.

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. ...

Bit by bit, it seems 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. Therefore, we launched an initiative:

First of all, 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 the incandescent lamp with the fourth-generation LED green light source. 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.

When we are enjoying a well-off life, are we aware that the shortage of resources is approaching our life? Water crisis, electricity shortage and oil crisis all tell us profoundly that resources are limited and barren, but human reproduction will be passed down from generation to generation. Overexploitation of minerals, deforestation and water pollution have made our country no longer "vast in territory and abundant in resources", and also made our contemporary people taste the bitter fruit brought by quick success and instant benefit.

Therefore, it is urgent to protect our limited human resources and the foundation on which we live and develop. Therefore, we strongly propose to the students in the whole region: save resources, starting from you and me, save every kilowatt hour, every drop of water, every piece of paper and every grain, and effectively play a vital role and play a leading role in the action of * * * to create a conservation-oriented school.

First, establish a correct concept of saving. Fully understand the grim reality of China's resource shortage, conscientiously study and implement Scientific Outlook on Development, advocate the concept of saving glory and wasting shame, enhance the awareness of saving, and set an example.

Second, save electricity. Don't turn on the light when there is enough light; Don't turn on one more lamp when you can use one; Put an end to fluorescent lamps and ever-burning lamps

Third, save water. Avoid turning on the tap, advocate washing your face and hands with a washbasin, and reasonably reduce the bathing time; After running out of water, tighten the faucet in time and turn it off when you see dripping water.

Fourth, save rice. Actively advocate the wind of civilized dining, insist on dining in the canteen, and don't waste every grain.

Fifth, save paper. The paper advocates double-sided use as much as possible.

Sixth, save money. Moderate consumption, reasonable expenditure, careful calculation, persist in saving a little every day, and form a good habit of being good at financial management.

Seven, actively participate in environmental protection activities. Vigorously carry out classified recycling of used batteries and daily necessities, and promote the use of recycled paper; Try not to use disposable chopsticks and use degradable disposable lunch boxes; Adhere to participate in environmental volunteer service activities once a month.

Eight, actively carry out the invention and creation activities of saving technology. We should be brave in innovation and be good at creation, and strive to provide strong technical support for resource conservation through tricks, small creations and small inventions, and constantly promote resource conservation.

Nine, actively and widely publicize the awareness of conservation, and vigorously carry out resource conservation and rationalization activities. Give suggestions, do your duty, contribute to building a conservation-oriented society, and strive for conservation-oriented families, conservation-oriented classes, conservation-oriented schools, conservation-oriented societies (collectives) and individuals. Spread the awareness of saving, and promote the whole school to form a good fashion of cherishing and saving resources.

I hope it helps you.
