Ji Yu sinks the boat, in our large developing country with a population of 1.3 billion people, if everyone does not pay attention to conserving resources, then our resource reserves will not be able to carry the development of the Chinese nation's boat;
Drop by drop, if China with a population of 1.3 billion people really do practicing economy and opposing wastage, the power it brings together will not only be the The power it brings together will not only be the support for our country's journey into the future, but also our nation's gift to the earth and to mankind.
Don't do evil, don't do good. Life to eliminate waste can be done by everyone, can save where the head is.
Shower soap when turning off the faucet, a bath can save 60 liters of water; with a cup of water to brush your teeth, only 0.5 liters of water, if you leave the tap on for 5 minutes, it is a waste of 45 liters of water; toilets use water-saving appliances, each time you can save 4-5 liters of water; wash dishes with a basin to catch the water to wash, instead of turning on the faucet, a meal can save 100 Liters of water ......
The nation's 1.3 billion people use one less pair of disposable wooden chopsticks per person, which means thousands of acres of forests are saved from deforestation. Every family in the country uses one less plastic bag per day, which can save a lot of oil consumption and reduce the pollution of the environment.
Recycling 1 ton of waste paper can produce 800 kilograms of good paper, which can cut down 17 trees, save 3 cubic meters of landfill space, and also save more than half of the energy used in papermaking, and reduce water pollution by 35%.
If the use of energy-saving light sources, our lighting power consumption will drop 60%, a year can save 74 billion kilowatt-hours of electricity, equivalent to saving 29.89 million tons of standard coal. If the country's existing 130 million refrigerators are all replaced by power-saving refrigerators, the annual power savings of 43.132 billion kilowatt-hours, equivalent to half of the Three Gorges Hydropower Station's power generation ......
It is not an exaggeration to say that each of our hands are holding the precious "resource
It is no exaggeration to say that each of us is holding precious "resources" in our hands, and we have the power to kill or take away the "lifeblood" of the development of these nations, and we have to destroy it and love it in the actions of each one of us.
In the 1950s and 1960s of the last century, the party and the government once vigorously advocated saving a degree of electricity, a drop of water, a drop of oil, a catty of coal, an inch of cloth spirit. Now the economy has developed, income has increased, the days are better, but the spirit of thrift is not only not outdated, but with the development of the times has a richer meaning.
"Thrift nourishes virtue," and since ancient times, the Chinese people have always taken thrift as a virtue worth honoring. Today, our 20-word civic moral program also includes thrift and frugality in the book.
Choosing thrift is not only choosing a way of life and pursuing a spiritual quality, it is also establishing a path towards the future.
It is called sustainable development.
It requires 1.3 billion people to make a concerted effort and to be physically active.
1. Natural resources are mostly non-renewable, and if we want sustainable development, we need to use them wisely
2. Destroying natural resources often destroys the environment, and worsens the environment in which humans live
Building a conservation-oriented society is a slogan we shout when we cherish and conserve resources. But how can we really conserve resources? Why should we strongly recommend saving? Please listen to my heart!
First of all, water resources. China's total water resources of 2.8 trillion cubic meters or so, ranking sixth in the world, per capita water accounted for more than 2,100 cubic meters, accounting for only a quarter of the world's per capita level, belonging to the country of water shortages, the country's more than 600 cities in more than 400 water shortages. Especially in the western region of the water shortage is very serious, some mountainous places and even people, livestock drinking water are very difficult.
China's water is facing serious problems, so we have to cherish water resources, water conservation. For example: after using the water, to tighten the tap, so as not to cause "a river of water to the east" of the phenomenon of waste, if you find that the faucet is broken, to repair in time, to avoid the loss of a large amount of water, we should not underestimate the discarded batteries, because a button battery will contaminate the 600 tons of water, if you throw it to the water, the water will be undrinkable. We should collect the batteries and send them to the recycling station, so that we can avoid polluting the water and make the batteries recycled, killing two birds with one stone. We can't just pay lip service to it, we have to take action!
Not only to save water, but also to save forest resources. The total amount of forest resources in our country is insufficient, the forest coverage rate is only 18.21%, equivalent to the world average forest coverage rate of 61.52%; the national per capita forest area and per capita forest reserves were less than a quarter of the world per capita level and one-sixth. The quality of forests is not high, with an average storage capacity of only 84.73 cubic meters per hectare, equivalent to 84.86% of the world average.
This is the alarm that forest resources have sent to us! We have to save the use of forest resources, first of all, can not throw paper, nor take the unwritten paper folding aircraft and other small crafts, not to cut down indiscriminately, trampling on plants and trees, to plant trees, flowers and trees; not to use disposable things, such as paper cups, wood blocks and so on. At school, we should set up a "green bank" and pick up paper scraps and handkerchiefs that we have discarded before. When we eat out, we should bring our own spoons and chopsticks. Students, let's act together to save and utilize our limited forest resources.
We can't live without electricity everywhere. Electricity brings us all kinds of convenience, but we have to save electricity, because electricity is almost produced by burning standard coal, and the coal stored in our country is only enough to mine for 100 years! Think about it, what will our children and grandchildren do after 100 years? Therefore, we have to conserve electricity. First of all, from the self to start, I keep in mind that "people come to the lights on, people go out of the lights", the summer season, open the air conditioning, do not set the temperature too low, suitable for on it. The usual lighting, as far as possible with energy-saving lamps, because the ordinary light bulbs to a large amount of electricity into heat, only a small number of turn into light, and energy-saving lamps to electricity almost into the light.
"Cherish resources, advocate saving" is the obligation of each of our citizens. For the sake of our better tomorrow, please act quickly!
"Looking forward, looking forward, the east wind came, the footsteps of spring is close ......"
It is Mother Earth, bring us one after another beautiful spring.April 22, when the 37th April 22, when the 37th "World Earth Day" stepped in the spring dance to our side, we can not help but think: how we should be good to Mother Earth, how to cherish Mother Earth to give us the miles of spring.
Treating the earth well - cherishing resources and sustainable development - is the main theme of this spring.
But the current situation in our country, whether it is land resources or mineral resources, its protection, utilization and sustainable use of the situation, are not optimistic. We have to ask: the earth's spring, is it forever?
Despite our implementation of the world's most stringent land management system, but in some places, the indiscriminate occupation of agricultural land and basic farmland, but also happen from time to time; our large and small cities, paved with reinforced concrete "cake", is still expanding in all directions, devouring the surrounding hectares!
Although the supply of mineral resources has become a bottleneck in the rapid development of economic constraints, but in some places, to waste and destroy resources as a symbol of the unlicensed small mines, is still in the non-stop indiscriminate mining; even in the big mines, "eat half and throw half of the" sloppy mining methods Even in large mines, "eat half and throw away half" of the rough way of mining is also continuing; indiscriminate piling of tailings, not only so that the mineral resources could have been utilized miserably discarded, but also in the rainy season may be formed mudslides, into the destruction of fields, crops and people's lives and property killers; mining hollow area of the ground subsidence and fissure, not only make the farmers lose their livelihoods of the land resources, but also threaten the safety of their residence; We are the world's most water-scarce country, but water for production and living is still being squandered at will, and precious groundwater is being over-exploited or polluted; our energy is already in short supply, but the crude heating of newly built housing stock is still wasting oil and coal resources. ......
Today, we are facing an overall tightening of supply and demand for land and mineral resources, but we are still facing an overall tightening of supply and demand for land. supply and demand of land and mineral resources, we must change the status quo of rough utilization of land resources, inefficiency and serious waste. The CPC Central Committee and the State Council attach great importance to the saving and intensive utilization of land resources, requiring us to have a high sense of historical responsibility, a strong sense of worry and a broad vision of the world, accurately grasp the staged characteristics of China's development, base on scientific development, focus on independent innovation, accelerate the transformation of the mode of economic growth, take resource conservation as a basic national policy, develop a circular economy, and Protect the ecological environment, accelerate the construction of a resource-saving and environment-friendly society, and promote economic development in harmony with population, resources and the environment.
In order to build a conservation-oriented society, during the "Eleventh Five-Year Plan" period, the state set several binding hard targets that must be met: maintaining arable land reserves of 120 million hectares, reducing energy consumption per unit of GDP by about 20%, reducing water consumption per unit of industrial added value by 30%, increasing the effective utilization coefficient of water for irrigation to 0.5, increasing the effective utilization coefficient of water for industrial solids to 0.5, and increasing the effective utilization coefficient of water for irrigation to 0.5. The effective utilization coefficient of agricultural irrigation water has been increased to 0.5, and the comprehensive utilization rate of industrial solid waste has been increased to 60% (expected). Now, governments and enterprises at all levels are working hard to realize these goals, and every one of us citizens should work hard to realize these goals. Resource shortages and energy crises are all around us, "electricity shortage", "oil shortage", "coal shortage", "water shortage "and so on, are all the time in trouble with us. Cherishing resources depends on you and me. Only the whole society *** with the efforts, in order to enable us to get rid of the rapid development of the resource dilemma, towards resource-saving, environmentally friendly society.
Cherish resources, protect resources, save resources, everyone has the responsibility. Let us start from now, from me, from the little by little, cherish all the natural resources given to us by Mother Earth, so that our homes year after year spring ......
Summer, when the outdoor air temperature will be higher than the indoor, close the doors and windows to prevent the invasion of high temperatures outside; in the bedside, writing desk, kitchen counter, Restroom above the installation of breeze ceiling fans, dining room ceiling fans or floor fans to eliminate the summer heat, less or no air conditioning.

7, accidentally clothes touch the paint, in the dirty place on the cool oil, and then hit the soap wash twice, it is clean.
8, have a car family saving points. Going out as much as possible by public **** car, driving out of the car as little as possible to put some items, which can reduce the vehicle load and exhaust emissions. Vehicles unloading or waiting for people best off, driving at medium speed, not suddenly accelerate, try not to brake sharply on the way to ensure that there is enough gas in the tires, the vehicle stops the best not to store gasoline, so as not to evaporate and waste.
9, refrigerator power saving points. Put it in a cool and ventilated place indoors, and the wall should keep a certain distance. Keep the freezer clean and defrost in time. Don't put hot warm food into the refrigerator. Keep the refrigerator open for as short a time as possible. Choose suitable materials for packaging frozen food. Thaw frozen food in the freezer when you need to eat it.
10. One person wrote 20 golden ideas. Including bring your own toothbrush, advocate water-free day, free replacement of old faucets, in each unit to carry out the selection of the best savings, etc..
11, the installation of split-button flush toilet, according to the large and small stools, respectively, with large and small flow to flush the toilet, which can save a lot of tap water.
12, New Year's holidays do not send paper greeting cards, instead of using e-cards to send greetings by e-mail. Business card paper, office paper and envelopes should be made of recycled paper.
13, two hours of walking after dinner, both exercise and save electricity; winter before going to bed with electric blankets to preheat instead of air conditioning.
14, residential buildings can be divided into clear water and recycled water two water pipes, clear water pipe in the water for eating, washing, etc., after the use of water and then flow to the downstairs water storage will be filtered through an intelligent control of the water pump, the formation of recycled water, and then pumped to the roof tanks for flushing toilets, mops, watering, etc., which not only saves water resources, but also reduces the discharge of sewage.
15, it is suggested that in some urban and rural areas dug a small number of wells, the public can use the well water in summer washing and showering, I believe that more tap water can be saved.
16, fire hydrant from the ground vertical to underground horizontal, can effectively prevent the phenomenon of water waste due to fire hydrant was broken. Hydrant shelter box can be made of masonry, size, depth to be able to smoothly put in and out as appropriate.
17. "Intelligent ecological water-saving equipment", which can realize tap water recycling and reuse when washing cars through technical processing, has been awarded a national patent.
18, urban households solar water pipe installation is very inconsistent, and often leakage phenomenon, both affecting the cityscape, winter and easy to freeze. It is recommended that developers in the construction of residential buildings, the water and sewage pipes installed in the wall leading to the user's home, so beautiful and energy-saving.
19, now the family is characterized by a small population, and most of the family of three, which appeared to eat vegetables difficult problem. Vegetables to buy less, color and nutritional deficiencies; vegetables to buy more, resulting in waste, the establishment of community canteens can help office workers to reduce the burden of household chores, but also to make up for the lack of small families.
20, each local area to establish the waste products transfer market. Network market-based, and in some public **** places such as hospitals, stations, neighborhoods, shopping malls set up in front of the Internet platform, in order to timely access to the Internet to buy what they need; the state of this type of buying and selling behavior in addition to the necessary taxes in accordance with the tax law, without charging any fees.
21. 40 million yuan was invested at one time to renovate 10,000 cabs and buses, saving 200 million yuan a year in fuel costs. It is recommended that Nanjing City, cabs, buses for mandatory oil to gas conversion. The methods are as follows: increase gas refueling stations and promote oil and gas dual-fuel vehicles.
22, scientific treatment of drug packaging, today's drugs often have unnecessary multi-layer packaging, suggesting that manufacturers produce simple drugs, hoping that the public boycott the fine packaging of drugs.
23. It is recommended that the construction of large biogas digesters be promoted in rural areas to produce biogas by using straw from both seasons as fuel.
24. Set up an urban organic fertilizer supply company. Now the number of urban population is very considerable, but also produced a large number of human excreta, over the years these are discharged into the river through the sewers, polluting the environment but also a waste of resources, the organic fertilizer can be transported to the countryside in place of chemical fertilizers, saving and environmental protection.
25, it is recommended that the recycling of old furniture, reprocessing continue to use. This can save a lot of wood resources.
26, urn-style portrait sculpture. The urn is made into a portrait of the deceased, the back or below a small valve, the ashes of the deceased placed in, which can save a lot of land originally used for the burial of the dead.
27, install solar power generators on the roofs of most of the city's tall buildings to save energy and ease power.
28. Utilize tidal power from renewable energy sources. Jiangsu Province has more than 900 kilometers of coastline, the tide rises and falls twice a day, the difference between high and low tide levels up to more than 3 meters, contains a huge amount of energy, modern science and technology is fully capable of using tidal energy to generate electricity.
29, it is recommended that families use small energy storage air conditioning units and phase-change cold storage materials. When power supply is tight, the implementation of peak and valley electricity pricing policy for the energy storage air-conditioning technology provides a broad prospect for development. At present, large-scale cold-storage air-conditioners have been used in many parts of China, but they are used in large buildings. And small, domestic cold storage air conditioners have been slow to appear. The project has been awarded a national patent.
30, the use of urban high-rise top wind resources. Wind speed increases with height, the higher the building, the greater the wind, the greater its reserves of wind energy resources, the more adequate, the current big cities abound in more than 20-story high-rise buildings, such as in the high-rise building built on the roof of the structural wind or wind tunnel, the roof of the high-rise building can be year-round all-weather power generation conditions, the roof of the windmill, both power generation, but also a scenic spot.
31, the use of moonlight to lighting. Where the moonlight is better at night, you can open less or not open street lights, the meteorological department can measure a brightness coefficient, in what index under the switch street lights.
32, summer is here, the car parked outside, people just into the car often feel the temperature is too high, the body is very uncomfortable. It is recommended to use solar panels to do the roof, so that after the car is turned off, so that solar energy into electricity, start the car air conditioning.
33, "automatic beyond the trolley bus". City buses are the city's major oil users, exhaust pollution, if you can realize the electrification of public transport vehicles, rail, to solve the oil crisis and urban environmental protection are of great significance.
34, the use of high-pressure sodium lamp electronic ballast products in road lighting. The product has a good power saving effect, at present Japan`s, Europe and the United States has been industrialized, in the face of energy saving, "electricity shortage", electronic ballasts have a number of unique advantages, such as constant luminous flux, brightness, no flicker and so on.
35, in the urban heat island, the construction of heat pumping tower to make the heat island into a cool island, its shape like a big chimney. It uses the temperature difference between the surface and the air in the air, the surface of the hot air pumped to the high air to make the surface of the formation of low-pressure areas, the cold air in the air on a steady stream of precipitation through the surrounding area, supplemented to the heat island to reduce the surface temperature of the heat island. In order to reduce construction investment, can be attached to the heat pumping tower in the high-rise building, the bottom of the heat pumping tower as a parking lot.
36, it is recommended that more production and design of free combination of clothing, that is, buy a piece of clothing, according to the weather mood, personal preferences, etc., at any time to combine the collage collar, sleeves, pockets and other parts, saving a lot of good clothing material and fashion effect, can be done in one coat, more than the front and back to wear two sides of the science.
37, suggested that the postal service should not keep changing the standard envelope printing standards, otherwise every change will produce a large number of discarded envelopes, resulting in unnecessary waste.
38, to build a "conservation-oriented society" as a project, not just in the slogan, the relevant departments should be from the policy, institutions and other aspects of the supervision and implementation of conservation initiatives, especially to promote the use of conservation equipment.
38, do not engage in urban lighting projects, reasonable and economical use of lighting, except on holidays.
40, society should form a "value-added savings system" to reward and penalize the way to improve the overall quality of public savings.
This is an article I read in the People's Daily. As far as I know, there is only one mausoleum in Beijing, the Badaling Mausoleum, where tree burials are practiced, but not others.
On June 16, the tree burial park at Badaling Mausoleum in Beijing will officially open. As of the evening of June 5, nearly 30 people
have registered to buy a tree burial space. Walking into the mausoleum, in the traditional burial area, rows and rows of black or white tombstones row
Compact rows, standing quietly, from a distance, we know that this is a cemetery. In the soon-to-be-opened tree burial area, the view is
very different. Pines and poplars grow vigorously, grass and shrubs grow under the trees, and between the trees
birds sing happily, so close to nature that it seems to be a natural forest park.
Tensioned land resources do not allow the "dead" and "living" to compete for land
For such a new form of burial, mausoleum general manager Wu Yali is this way of looking at it: "Tree burial is
The death of a person who has been buried in a tree is a way of life. p>
The ashes of the deceased will be buried under the tree, not to form a grave, on the one hand, let a person have a real return to nature, on the other
On the other hand, also let a person feel that the life of loved ones through a tree to continue."
Account manager Mr. Han told reporters that since the mausoleum released the news of tree burial, every day to receive
to a dozen about the tree burial consulting calls, 80% of which are the elderly themselves, there have been a number of elderly
people said that they want to persuade their children to choose a tree burial for their own behind. The reporter managed to reach one of the counselors, Mr. Wang
. Mr. Wang said he preferred tree burials because he visited some cemeteries and saw
that some cemeteries took up large plots of land and had luxurious decorations, which he felt was unnecessary. "The people are gone,
and still take up so much space, it's better to leave the land for the descendants to do something useful."
In fact, China's tight land resources no longer allow the "dead" to compete with the "living" for land.
The Ministry of Land and Resources data show that although China's land area ranks third in the world, but arable land and land resources are
relatively scarce, with a per capita land area of 0.77 hectares, and per capita arable land area of only 0.106 hectares. And now China's
desertification area is growing at a rate of 2,460 square kilometers per year, and the total amount of soil lost each year reaches more than 5 billion
tons.
Experts say the reasons for the shortage of land resources in China are manifold, with the dead taking up the living
land, an easily overlooked reason. There are reports that cemeteries in some areas occupy more land than "the average living area of a living person," and that expanding cemeteries are encroaching on increasingly scarce land resources.
A large population and a shortage of land resources has always been a contradiction in China's economic development. At present, China
20 million new births each year, the population mortality rate of about 6 per thousand, only Beijing cremated remains each year
in more than 70,000 units. The number of the dead is the cumulative increase day after day, every year cemetery in the land any little
quantitative growth, will make the urban land supply and demand contradiction more and more prominent, will make the scarce land resources day
increasingly overburdened.
Experts from the National Greening Committee have pointed out that a good solution is to make tombstones and graves as
free as possible from taking up land resources and damaging the natural environment as much as possible.
Tree burials save resources obviously: a family of people can choose to "reunite" under the same tree
Land, a limited and valuable resource, consume a little less, while the human race has to reproduce forever
Diffracted.
Funeral industry sources told reporters that in terms of saving land, the urn into the ground than the coffin into the ground a
big step forward. Because placing the urn will not occupy more than 1 square meter, but a burial grave occupies at least 12 square
meter, a coffin needs to use 0.5 cubic meters of wood, even if only 1,000 people per year burial calculations, but also to take up
Land 1.2 hectares, wasting 500 cubic meters of wood.
But the land resources currently consumed by the placement of urns each year are not to be underestimated. Although funeral management
regulations around the world require that graves for the interment of ashes should not occupy more than 1 square meter each. But the funeral industry to
reporter revealed that even if the strict implementation of this provision, the actual footprint of each grave will not be less than 3 square meters, because
build a cemetery to have the necessary aisles, greening and other ancillary facilities, these amortized area counted down to the implementation of the "1 square
meter Ordinance
The implementation of the "1 square meter ordinance" has greatly reduced the size of the area.
Some people have done calculations, tree burials occupy only 1/10 of the land of the traditional tomb. to the Badaling Mausoleum's
practice, for example, they dug under the tree a 30 cm x 30 cm x 30 cm pit, the ashes buried deep into
to go, occupying as little as 0.09 square meters, only 1/10 of 1 square meter.
People can also choose to "reunite" under the same tree, which will save more considerable land. China
National Greening Foundation office deputy director Wang Jiubuan said the land occupied by tree burials, in fact, support a tree,
can be regarded as a green area. The large-scale construction of cemeteries to make the "green mountain whitening" phenomenon is serious, tree burial not only
can reduce the land, the future can also further increase forest resources. It is reported that the Badaling Mausoleum in each tree
burial space will be donated to the China Greening Foundation 500 yuan, for the protection of the Great Wall and greening work. Tree burials that have
powerfully promoted greening work.
Water resources
To cherish resources and protect the environment, we can totally start from the small things around us, such as: not littering, paying attention to saving water and electricity resources, not using disposable items, etc., all of these are ways to cherish resources. As long as we have the perseverance, we will definitely be the little standard bearer of cherishing resources.
If most people destroy the environment, then the country will need to put out a lot of resources to control the environment. This will not only require a lot of manpower, but also a lot of material resources. But if we all become ambassadors for the protection of the environment, then we not only save resources, but also save manpower and material resources, who wants to waste resources? If most people waste water, then there will be no water to drink in the future, and even if there is water to drink, it will be very precious. A newspaper once said: about 70 years later, water will be more expensive than oil.
Water, the basic substance of the earth, is so worthy of our praise! It is she who gave birth to the world, all beings; it is she who provides energy for life, so that life can survive; or she, so that life continues to develop, more and more prosperous, more and more developed. So, "water, is the source of life", is no exaggeration.
If people do not cherish water resources, then the last drop of water in the world is human tears.
But is water inexhaustible? We can answer with certainty: no. Although 70.8% of the earth is covered by water, 97.55% of the water is seawater, which is neither directly drinkable nor irrigable. Of the remaining 2.5% of fresh water, less than 1% of the world's total fresh water is actually available to mankind. It is true that from the primitive life on earth until now, water has been in the service of life, work hard, never stop. But I don't know if you have ever thought: water patience is also a limit, today's water resources have been in short supply!
Forest Resources
The total amount of forest resources in China is insufficient, the forest coverage rate is only 18.21%, equivalent to the world's average forest coverage rate of 61.52%; the national per capita area of forests and per capita forest reserves were less than a quarter of the world's average per capita level and one-sixth. The quality of forests is not high, with an average volume of only 84.73 cubic meters per hectare, equivalent to 84.86% of the world average.
This is the forest resources to us issued an alarm! We have to save the use of forest resources, first of all, can not throw paper, and do not take the unwritten paper folding aircraft and other small crafts, and do not want to cut down indiscriminately, arbitrarily trampled on flowers, plants and trees, to plant forests, flowers and trees; do not use disposable things, such as paper cups, wood blocks and so on. At school, we should set up a "green bank" and pick up paper scraps and handkerchiefs that we have discarded before. When we eat out, we should bring our own spoons and chopsticks. Students, let's take action together to save and utilize our limited forest resources.
Save electricity resources
We can't live without electricity everywhere. Electricity brings us all kinds of convenience, but we have to save electricity, because electricity is almost produced by burning standard coal, and the coal stored in our country is only enough to mine for 100 years! Think about it, what will our children and grandchildren do after 100 years? Therefore, we have to conserve electricity. First of all, from the self to start, I keep in mind that "people come lights on, people go lights out", the summer season, open the air conditioning, do not set the temperature too low, suitable for on it. The usual lighting, as far as possible with energy-saving lamps, because the ordinary light bulbs to a large amount of electrical energy into heat, only a small number of light, and energy-saving lamps to electrical energy almost into the light.
The importance of cherishing electric resources
Nowadays, although people's life is getting better and better day by day, the resources are decreasing! Therefore, we have to protect the environment, but also low-carbon life
People, just for personal and immediate interests, uncontrolled mining, indiscriminate cutting of trees and forests, sewage discharged into the creeks, the sea and some other lakes. Many innocent animals are homeless and wandering around. Some of them die in hunger and cold. Can human beings bear to see their homes destroyed? Can we just watch animals, rivers and some other friends being harmed? Aren't we afraid that one day the earth will die and so will human beings? Although everyone knows to protect the Earth, but how many people to do, how many people really to realize this great plan?
People use electricity in an uncontrolled way. We know: one degree of electricity can be used to make steel 1.5 kilograms, 53 kilograms of coal can be mined, 16-inch fan can run for 16 hours, 10-watt lamps can be illuminated for 100 hours, 25-inch color TV can work for 12 hours. ...... can be seen, electricity is how useful it is! Saving 1 kilowatt hour of electricity can save 400 grams of standard coal, and reduce emissions into the atmosphere of sulfide and nitrogen compounds and other emissions. Saving electricity can also reduce acid rain, but also slow down the warming of the planet.
We must also be extremely careful when using electrical appliances. However, in real life, people often tend to ignore the safety of it. Dangerous things can happen from time to time. So the necessary electrical appliances, you can pull the plug after use, not only is not easy to safety accidents, but also save electricity, which is a two-for-one thing.
So, we humans must protect the environment to save energy, science to go to the electricity, to protect the home we live on!
