On the importance of cherishing resources

Saving resources depends on everyone's actions.

Accumulate a feather and sink a boat. In our developing country with a population of1300 million, if everyone does not pay attention to saving resources, then our resource reserves will not be able to carry the ships developed by the Chinese nation;

If China, with a population of 654.38+0.3 billion, really practices economy and opposes waste, the strength it embodies will not only be the support for our country to move towards the future, but also a gift from our nation to the earth and mankind.

Don't do it with little evil, and don't do it with little good. Everyone can stop wasting things in life and bow down where they can be saved.

Turn off the faucet when washing soap in the shower, and you can save 60 liters of water in the shower; Brush your teeth with a glass of water, only 0.5 liter of water. If you leave the tap on for 5 minutes, you will waste 45 liters of water. The toilet uses water-saving appliances, which can save 4-5 liters of water each time; When washing vegetables, you can save 65,438+000 liters of water by replacing the tap with a basin.

With a population of 654.380+0.3 billion, less than one pair of disposable wooden chopsticks is used, which means that thousands of acres of forests are protected from bad luck. Every family in China uses one less plastic bag every day, which can save a lot of oil consumption and reduce environmental pollution.

Recycling 1 ton waste paper can produce 800 kilograms of good paper, cut down less 17 trees, save 3 cubic meters of landfill space, save more than half of papermaking energy and reduce 35% of water pollution.

If energy-saving light sources are adopted, our lighting power consumption will be reduced by 60%, and 74 billion kWh of electricity can be saved a year, which is equivalent to saving 29.89 million tons of standard coal. If all the existing 65438+300 million refrigerators in China are replaced by energy-saving refrigerators, 4,365,438+32 million kWh of electricity can be saved every year, which is equivalent to the power generation of half the Three Gorges Hydropower Station. ...

It is no exaggeration to say that each of us holds precious "resources" and the power to stifle and seize the "lifeblood" of the development of these ethnic groups, and the harm to it and love lies in our actions.

In 1950s and 1960s, the Party and the government vigorously advocated the spirit of saving electricity, a drop of water, a drop of oil, a catty of coal and an inch of cloth. Now the economy has developed, the income has increased and the life is better, but the spirit of thrift is not out of date, but it has become more meaningful with the development of the times.

Since ancient times, the Chinese nation has always regarded thrift as a virtue worth promoting. Today, our 20-word civic moral program will also be written into the book of thrift.

Choosing frugality is not only to choose a lifestyle and pursue a spiritual quality, but also to build a road to the future.

Its name is sustainable development.

Need1300 million China people to work together and practice together.

1. Most natural resources are non-renewable, and human beings must make rational use of them if they want to develop sustainably.

2. Destroying natural resources will often destroy the environment and worsen the living environment of human beings.

"Building a conservation-oriented society" is our slogan to cherish and save resources. However, how can we really save resources? Why do you strongly recommend saving? Please listen to my heart below!

Let's start with water resources. The total amount of water resources in China is about 2.8 trillion cubic meters, ranking sixth in the world. The per capita water consumption is more than 2 100 cubic meters, accounting for only a quarter of the world's per capita level. It is a country short of water, and more than 400 cities in China are short of water. In particular, the water shortage in the western region is very serious, and it is very difficult for people and animals in some mountainous areas to drink water.

Water use in China is facing a serious problem, so we should cherish water resources and save water. For example, after running out of water, tighten the faucet to avoid the waste phenomenon of "one river of clear water flows eastward" If the faucet is found to be broken, it should be repaired in time to avoid a lot of water loss. Don't underestimate the discarded batteries, because a button cell will pollute 600 tons of water. If it is thrown into the water, the water can't be drunk. We should collect the batteries and send them to the recycling station, which can not only avoid polluting the water source, but also recycle the batteries, killing two birds with one stone. You can't just talk without practice, you have to act!

Save not only water, but also forest resources. The total amount of forest resources in China is insufficient, and the forest coverage rate is only 18.25438+0%, which is equivalent to the world average forest coverage rate of 6 1.52%. China's per capita forest area and per capita forest stock are less than one quarter and one sixth of the world average respectively. The forest quality is not high, and the average volume per hectare is only 84.73 cubic meters, which is equivalent to 84.86% of the world average.

This is a warning from forest resources! We should use forest resources sparingly. First of all, don't throw manuscript paper around, don't fold small crafts such as airplanes with unwritten paper, and don't cut down and trample flowers and trees at will. We should plant trees and care for them. Don't use disposable things, such as paper cups and wood blocks. At school, we should set up a "green bank" to collect discarded scraps of paper and handkerchiefs. When eating out, bring your own spoon and chopsticks. Students, let's act together to save and use our limited forest resources.

Electricity is indispensable everywhere. Electricity has brought us various conveniences, but we should save electricity, because almost all electricity is generated by burning standard coal, and the coal stored in China is only enough for mining 100 years! Think about it, 100 years later, what will our descendants do? Therefore, we should save electricity. First of all, start from yourself and remember that "people turn on the lights and people turn off the lights". In midsummer, when turning on the air conditioner, don't adjust the temperature too low, just adjust it appropriately. Usually lighting, use energy-saving lamps as much as possible, because ordinary light bulbs convert a lot of electric energy into heat energy, only a small part into light, and energy-saving lamps almost convert electric energy into light.

"Cherish resources and advocate economy" is the obligation of every citizen. For our better tomorrow, please act quickly!

"Looking forward to, looking forward to, the east wind is coming, and the pace of spring is near ..."

Mother Earth has brought us one beautiful spring after another. On April 22nd, when the 37th "Earth Day" came to us with the footsteps of spring, we couldn't help thinking about how to treat Mother Earth well and how to cherish the spring scenery in Wan Li given to us by Mother Earth.

Be kind to the earth-cherish resources and sustainable development are the themes of this spring.

However, the current situation of protection, utilization and sustainable utilization of land resources and mineral resources in China is not optimistic. We have to ask: is the spring of the earth forever?

Although we implement the strictest land management system in the world, in some places, the phenomenon of indiscriminate occupation and use of agricultural land and basic farmland still occurs from time to time; Our large and small cities, this "pie" paved with reinforced concrete, are still expanding in all directions, devouring the surrounding cultivated land. ...

Although the supply of mineral resources has become the bottleneck of rapid economic development, in some places, unlicensed small mines marked by waste and destruction of resources are still being exploited and dug indiscriminately; Even large mines continue the extensive mining method of "eating half and throwing half"; Littering tailings not only makes the mineral resources that can be used originally abandoned, but also may form debris flow in rainy season, which becomes the killer of destroying fields, crops and people's lives and property; Ground subsidence and ground fissures in mined-out areas not only make farmers lose the land resources they depend on for survival, but also threaten their life safety. We are the country with the most water shortage in the world, but the water for production and life is still squandered at will, and the precious groundwater is overexploited or polluted; Our energy is already in short supply, but the extensive heating of new houses like mushrooms after rain is still wasting oil and coal resources. ...

Today, the supply and demand of land and mineral resources are in full swing, so we must change the current situation of extensive utilization, low efficiency and serious waste of land resources. The CPC Central Committee and the State Council attach great importance to the economical and intensive utilization of land and resources, which requires us to accurately grasp the stage characteristics of China's development with a high sense of historical responsibility, a strong sense of hardship and a broad world vision, base on scientific development, pay attention to independent innovation, accelerate the transformation of economic growth mode, take resource conservation as a basic national policy, develop circular economy, protect the ecological environment, accelerate the construction of a resource-saving and environment-friendly society, and promote the coordination of economic development with population, resources and environment.

In order to build a conservation-oriented society, during the Eleventh Five-Year Plan period, the state has set several binding hard targets that must be achieved: the number of cultivated land will remain at 65.438+0.2 billion hectares, the energy consumption per unit GDP will be reduced by about 20%, the water consumption per unit industrial added value will be reduced by 30%, the effective utilization coefficient of agricultural irrigation water will be increased to 0.5, and the comprehensive utilization rate of industrial solid waste will be increased to 60% (expected). Now, governments and enterprises at all levels are working hard to achieve these goals, and every citizen of us should work hard to achieve these goals. Resource shortage and energy crisis are around us, and "electricity shortage", "oil shortage", "coal shortage" and "water shortage" are bothering us all the time. Cherish you, me and his resources. Only with the concerted efforts of the whole society, Qi Xin can get rid of the rapidly developing resource dilemma and move towards a resource-saving and environment-friendly society.

It is everyone's responsibility to cherish, protect and save resources. Let's start from now on, from me, from dribs and drabs, cherish all the natural resources that Mother Earth has given us, and make our home spring bright every year. ...

When the outdoor temperature will be higher than the indoor temperature in summer, close the doors and windows to prevent the outdoor high temperature from invading; Install breeze ceiling fans above the bedside, writing desk, kitchen counter and bathroom, and install ceiling fans or floor fans in the dining room to cool down, with little or no air conditioning.

When the rice cooker cooks, the soup will be dried and kept warm for 10 minutes, and then the power will be cut off. Steaming rice with waste heat can save electricity. Turn off the air conditioner after two hours at night, turn on the breeze ceiling fan with low power consumption, and sleep comfortably all night.

Wash vegetables with daily rice washing water, mop the floor with vegetable washing water, and then flush the toilet to save clean water. Set the fan regularly before going to bed every night. If you use air conditioning, turn it up a little bit, and turn off the power when you go out.

After the public's water consumption exceeds a certain range, the water fee is increasing, for example, the price within 3 tons per month is calculated normally.

Fill the discarded plastic beverage bottles with water and put them in the toilet tank in the bathroom to increase the water resistance. Flushing after urinating can save a lot of water.

Find a used latex plastic bucket, cover the screen window with iron wire and cover it on the mouth of the bucket, so that the water for washing vegetables at home can be poured into the bucket and filtered, which can not only mop the floor but also flush the toilet, saving a lot of water.

1. Students are advised not to take the textbooks away after use and leave them to the students in the next class. After the implementation, tuition fees can be appropriately reduced, and the virtue of saving can be cultivated from bit by bit.

2. When the gas stove is burning, there will be heat leakage at the bottom of the pot and around the flame radiation area, which will not only waste energy, but also increase the kitchen temperature in summer and affect human comfort. The solution is: using stainless steel and other raw materials, it is pressed into a double-layer empty-bladder energy-saving hot water pot pad with a spacing of 2-5cm, a flat bottom and a round bottom shape, with a water injection port and a volume of about 2 liters of water. Without affecting the temperature of the main pot, the water temperature in the chafing dish pad can be increased by about 15℃, which can be used for bathing in summer and washing dishes in winter.

3. Add a controllable device to the ballast of the existing 40-watt bulb, so that when the light is turned on for the first time, the light is weak but the object can be seen clearly; If you want to read your writing homework, just open it again. This can also save a lot of electricity.

4. Introduce waterless car washing service in the community, so that 1 liter of water can wash up to 8 to 10 cars. The tools and materials are as follows: a bottle of anhydrous car cleaner (500 ml can be used for 30~50 times), a watering can for watering flowers at ordinary times, a soft brush, two soft cotton towels and a wax mop.

5. One person wrote 40 ideas. Including washing clothes with mulberry leaves, not using disposable goods, family planning and so on.

6. When the ceiling fan is started, first open the gear with the largest wind speed, and then switch to the small gear.

7. If you accidentally touch the paint, apply cool oil to the dirty place, then wash it with soap twice, and it will be clean.

8. the key point to save the owner. When going out, try to take the bus. When going out by car, put as few items as possible in the car, which can reduce the vehicle load and exhaust emissions. When the vehicle is unloading or waiting for someone, it is best to turn off the engine and drive at a medium speed, and don't suddenly accelerate. Try not to brake suddenly on the way to ensure that the tires have enough air. When the vehicle is parked, it is best not to store gasoline to avoid volatilization and waste.

9, refrigerator power saving points. Put it in a cool and ventilated place indoors and keep a certain distance from the wall. Keep the freezer clean and defrost it in time. Don't put hot and warm food in the refrigerator. The shorter the refrigerator is opened, the better. Choose suitable materials to package frozen food. Frozen food can be thawed in the refrigerator when it needs to be eaten.

10, one person wrote 20 golden ideas. Including bringing your own toothbrush, advocating waterless days, replacing old faucets for free, and selecting saving champions in various units.

1 1. For the toilet with split buttons, flushing the toilet according to the flow rate can save a lot of tap water.

12. Don't send paper greeting cards during China New Year, but use electronic greeting cards to send greeting emails. Business card paper, office paper and envelopes should use recycled paper.

13, walk for two hours after meals, which not only exercises but also saves electricity; The role of electric blanket preheating before going to bed in winter instead of air conditioning.

14. Residential buildings can be divided into two kinds of water pipes: clean water pipes and circulating water pipes. The water in the clean water pipe is used for eating and washing. After use, when it flows to the water storage downstairs, it will be filtered by the intelligent control pump to form circulating water, and then it will be pumped to the roof water tank for flushing toilets, washing mops, watering flowers and so on. This not only saves water resources, but also reduces sewage discharge.

15. It is suggested to dig a small number of wells in some urban-rural junctions, so that citizens can wash and shower with well water in summer, which is believed to save more tap water.

16, the fire hydrant is changed from vertical on the ground to horizontal underground, which can effectively prevent the waste of water resources caused by the broken fire hydrant. The fire hydrant bunker box can be made of bricklayers, and the size and depth should be suitable for smooth plugging and unplugging.

17, "intelligent ecological water-saving equipment", through technical treatment, can realize the recycling of tap water during car washing, and has obtained national patents at present.

18, the installation of solar water supply and drainage pipes for urban residents is very uneven, and water leakage often occurs, which not only affects the city appearance, but also easily freezes in winter. It is suggested that when building residential buildings, developers should install the upper and lower water pipes in the wall and lead them to the homes of users, which is both beautiful and energy-saving.

19. Nowadays, families are characterized by a small population, and most of them are families of three, so it is difficult to eat food. Buy less vegetables, poor color and nutrition; Buying too much food leads to waste. Building a community canteen can not only help office workers reduce the burden of housework, but also make up for the shortage of small families.

20, the establishment of waste swap market in various places. Give priority to the online market and set up online platforms in some public places, such as hospitals, stations, residential areas and shopping malls, so as to buy what you need online in time; The state does not charge any fees for this kind of business except the necessary taxes and fees stipulated in the tax law.

2 1, a one-time investment of 40 million 1 10,000 taxis and buses can save 200 million yuan in fuel costs every year. It is suggested that taxis and buses in Nanjing be forced to change from oil to gas. The methods are: increasing gas filling stations and popularizing oil-gas dual-fuel vehicles.

22. Scientifically handle the problem of drug packaging. Nowadays, drugs often have unnecessary multi-layer packaging. It is suggested that manufacturers produce simple drugs and hope that the public will resist fine packaging drugs.

23. It is suggested to promote the construction of large-scale biogas digesters in rural areas, and use two-season straw as fuel to produce biogas.

24, the establishment of urban organic fertilizer supply company. At present, the urban population is very large, which also produces a lot of human excrement. These have been discharged into rivers through sewers for many years, polluting the environment and wasting resources. This kind of organic fertilizer can be transported to the countryside to replace chemical fertilizer, which is economical and environmentally friendly.

25. It is suggested to recycle old furniture and reuse it after reprocessing. This can save a lot of wood resources.

26, urn portrait sculpture. The urn is made into a portrait of the deceased, and a small valve is installed on the back or under it to put the ashes of the deceased, thus saving a lot of land originally used for burying the deceased.

27. Install solar generators on most high-rise buildings in the city to save energy and ease the use of electricity.

28, the use of renewable energy tidal power generation. The coastline of Jiangsu province is more than 900 kilometers, and the tide rises and falls twice a day, with a difference of more than 3 meters. It contains enormous energy, and modern technology is fully capable of using tidal energy to generate electricity.

29. It is recommended that families use small energy storage air conditioners and phase change cold storage materials. In the case of tight power supply, the implementation of peak-valley electricity price policy provides a broad development prospect for energy storage air conditioning technology. At present, large-scale cold storage air conditioners have been used in many places in China, but they are all used in large buildings. However, small and domestic cold storage air conditioners have not yet appeared. This project has obtained the national patent.

30, the use of urban high-rise headwind resources. The wind speed increases with the height. The higher the building, the stronger the wind, and the richer the wind energy resources it reserves. Now there are many high-rise buildings with more than 20 floors in big cities. For example, building a structural tuyere or wind tunnel on the roof of a high-rise building can generate electricity all the year round, and building a windmill on the roof can not only generate electricity, but also serve as a landscape.

3 1, lighting by moonlight. In places with good moonlight at night, street lamps can be turned on or off less, and the meteorological department can completely measure a brightness coefficient, at which index the street lamps can be turned on and off.

32. When summer comes and the car is parked outdoors, I often feel that the temperature is too high and my body is very uncomfortable when I first get on the bus. It is suggested to use solar panels as the roof, so that after the car is turned off, the solar energy can be converted into electric energy and the air conditioner in the car can be started.

33. "Automatically overtake trolleybus". City buses are big consumers of oil and waste gas. If buses can be electrified, it is of great significance to solve the oil crisis and protect the urban environment.

34. High-voltage sodium lamp electronic ballast products are used for road lighting. This product has good power saving effect and has been industrialized in Japan, Europe and America. In the face of energy saving and power shortage, electronic ballast has many unique advantages, such as constant luminous flux, constant brightness and no flicker.

35. In the urban heat island, the heat removal tower is built to cool the heat island, which looks like a big chimney. It uses the temperature difference between the surface and the air in the upper air to pump the hot air from the surface into the upper air, so that the surface forms a low-pressure area, and the cold air in the upper air will continuously settle around and replenish to the heat island, reducing the surface temperature of the heat island. In order to reduce the construction investment, the heating tower can be attached to a high-rise building, and the bottom of the heating tower can be used as a parking lot.

36. It is suggested to produce more clothes with free combination of designs, that is, to buy one piece of clothes, and to assemble collage collars, sleeves, pockets and other parts at any time according to the weather, mood and personal preferences, which saves a lot of good materials and has a fashionable effect. You can wear one more piece of clothes, which is more scientific than wearing it on both sides.

37. It is suggested that the postal department should not constantly change the printing standard of standard envelopes, otherwise every change will produce a large number of discarded envelopes, resulting in unnecessary waste.

Building a "conservation-oriented society" should be regarded as a project, not just a slogan. Relevant departments should supervise the implementation of saving measures from policies, systems and other aspects, especially promoting the use of saving equipment.

38, don't engage in city lighting project, reasonable and economical use of lighting, except holidays.

40. The society should form a "savings appreciation system" to improve the overall savings quality of citizens through rewards and punishments.

This is an article I read in People's Daily. As far as I know, there is only one tree burial in Badaling Cemetery in Beijing, and I don't know the others.

On June 16, the tree burial garden of Beijing Badaling Cemetery will officially open. As of the evening of June 5, there were nearly 30 people.

Register to buy a tree burial tomb. Walking into the cemetery, in the traditional cemetery area, rows of black or white tombstones are arranged.

The column is very compact and stands quietly, and it can be seen from a distance that this is a cemetery. In the upcoming tree burial area, the scenery

The point of view is completely different. Pines and poplars are thriving, and the trees are covered with grass and shrubs.

Birds are singing happily, so close to nature, as if it were a natural forest park.

The shortage of land resources does not allow the "dead" and "living" to compete for land.

For such a new form of funeral, Wu Yali, general manager of the cemetery, looks at it this way: "Tree burial is

Burying the ashes of the deceased under a tree does not constitute a grave. On the one hand, it makes people feel really back to nature. On the other hand,

On the one hand, it also makes people feel that the life of their loved ones is extended through a tree. "

Mr. Han, the account manager, told the reporter that since the cemetery released the news of tree burial, it has to be picked up every day.

There are more than a dozen telephone calls about tree burial, 80% of which are from the elderly themselves, and some of them are elderly people.

Some people say that they will persuade their children to choose tree burial for themselves behind their backs. The reporter contacted the consultant Wang.

Grandpa. Uncle Wang said that he tends to choose tree burial because he visited some cemeteries and saw

Some cemeteries cover a large area and are luxuriously decorated, which is unnecessary. "People are gone,

It still occupies such a large area, so it is better to leave the land to future generations and let them do something useful. "

In fact, the tight land resources in China no longer allow the "dead" and "living" to compete for land. country

Relevant data from the Ministry of Land and Resources show that although China's land area is the third in the world, cultivated land and land resources are similar.

For scarcity, the per capita land area is 0.77 hectares, and the per capita cultivated land area is only 0. 106 hectares. Now our country

The desertification area is increasing at the rate of 2460 square kilometers every year, and the total amount of soil lost every year reaches more than 5 billion.

Tons.

Experts say that there are many reasons for the shortage of land resources in China, among which the dead account for the living.

Land is an easily overlooked reason. It is reported that cemeteries in some areas occupy more land than those of the living.

The average living area is still large, and the expanding cemetery is encroaching on increasingly scarce land resources.

A large population and a shortage of land resources have always been the contradictions faced by China's economic development. At present our country.

Every year, the new born population is about 20 million, and the population mortality rate is about 6‰. Only the remains are cremated in Beijing every year.

More than 70 thousand. The number of the dead is increasing day by day, and every year the cemetery is at any point on the land.

The increase in quantity will make the contradiction between supply and demand of urban land more and more prominent, and will make land resources scarce.

Interests are overwhelming.

Experts from the National Greening Committee pointed out that a good solution is to make tombstones and graves available.

Can no longer occupy land resources, try not to destroy the natural environment.

Tree burial has obvious resource-saving effect: people in a family can choose to "reunite" under the same tree.

Land is a limited and precious resource. If you consume a little, you will consume less, and human beings will reproduce forever.

Pass it on.

People in the funeral industry told reporters that in terms of saving land, the burial of urns is one step ahead of the burial of coffins.

Stride. Because the area of the urn will not exceed 1 m2, a burial grave can cover at least1m2.

Meters, a coffin needs 0.5 cubic meters of wood, even if only 1000 people are buried every year, it should be filled.

Land 1.2 hectares, wasting 500 cubic meters of wood.

But at present, the land resources consumed by placing urns every year should not be underestimated. Although the funeral management in various places

According to the regulations, the area of each grave for burying ashes shall not exceed 1 m2. But people in the funeral industry

According to the reporter, even if this regulation is strictly implemented, the actual area of each grave will not be less than 3 square meters, because

To build a cemetery, it is necessary to have necessary supporting facilities, such as walkways and greening. These pool areas are calculated as "1 m2"

The implementation of the rice regulations has greatly reduced water.

It has been calculated that the land occupied by tree burial is only110 of traditional tombs. Badaling cemetery

For example, they dug a 30cm× 30cm× 30cm pit under the tree and buried the ashes deeply.

Yes, it only covers an area of 0.09 square meters, really only110 square meters. Wu Yali introduced a family.

Some people can also choose to reunite under the same tree, which will save more land. middle

Wang Jiuyuan, deputy director of the office of the National Greening Foundation, said that the land occupied by tree burial is actually a tree.

It can be regarded as a green area. The large-scale construction of cemetery makes the phenomenon of "albinism of green hills" serious, and tree burial not only

It can reduce land use and further increase forest resources in the future. It is reported that every tree in Badaling cemetery

The burial site will donate 500 yuan to china green foundation for the protection and greening of the Great Wall. Tree burial, yes

Greatly promoted the greening work.

water resource

Cherish resources and protect the environment, we can start from the small things around us, such as not littering, saving water and electricity resources and not using disposable goods. These are all ways to cherish resources. As long as we have perseverance, we will certainly become small pacesetters who cherish resources.

If most people destroy the environment, then the country needs a lot of resources to manage the environment. This requires not only a lot of manpower, but also a lot of material resources. However, if we all become ambassadors to protect the environment, then we will not only save resources, but also save manpower and material resources. Who wants to waste resources? If most people waste water resources, then there will be no water to drink in the future, even if there is water to drink, it is very precious. A newspaper once said that in about 70 years, water will be more expensive than oil.

Water, the basic substance on the earth, deserves our praise! She gave birth to the world and all sentient beings; It is she who provides energy for life and makes life survive; Or did she let life develop continuously and become more and more prosperous? Therefore, it is no exaggeration to say that "water is the source of life".

If people do not cherish water resources, then the last drop of water in the world is people's tears.

But is water inexhaustible? We can definitely answer: No, although 70.8% of the earth is covered with water, 97.55% of the water is seawater, which can neither be directly drunk nor irrigated. Of the remaining 2.5% fresh water, the water that humans can really use is less than 1% of the global total fresh water. It is true that from the appearance of primitive life on earth to the present, water has been serving life, working hard and never stopping. But I don't know if you have thought that there is a limit to the endurance of water, and now water resources are in short supply!

forest resources

The total amount of forest resources in China is insufficient, and the forest coverage rate is only 18.25438+0%, which is equivalent to the world average forest coverage rate of 6 1.52%. China's per capita forest area and per capita forest stock are less than one quarter and one sixth of the world average respectively. The forest quality is not high, and the average volume per hectare is only 84.73 cubic meters, which is equivalent to 84.86% of the world average.

This is a warning from forest resources! We should use forest resources sparingly. First of all, don't throw manuscript paper around, don't fold small crafts such as airplanes with unwritten paper, and don't cut down and trample flowers and trees at will. We should plant trees and care for them. Don't use disposable things, such as paper cups and wood blocks. At school, we should set up a "green bank" to collect discarded scraps of paper and handkerchiefs. When eating out, bring your own spoon and chopsticks. Students, let's act together to save and use our limited forest resources.

Save power resources

Electricity is indispensable everywhere. Electricity has brought us various conveniences, but we should save electricity, because almost all electricity is generated by burning standard coal, and the coal stored in China is only enough for mining 100 years! Think about it, 100 years later, what will our descendants do? Therefore, we should save electricity. First of all, start from yourself and remember that "people turn on the lights and people turn off the lights". In midsummer, when turning on the air conditioner, don't adjust the temperature too low, just adjust it appropriately. Usually lighting, use energy-saving lamps as much as possible, because ordinary light bulbs convert a lot of electric energy into heat energy, only a small part into light, and energy-saving lamps almost convert electric energy into light.

The importance of cherishing power resources

Now in life, although people's lives are getting better every day, resources are decreasing! Therefore, we should protect the environment and live a low-carbon life.

People, just for personal and immediate interests, exploit and chop down trees and forests without restraint, and discharge sewage into some lakes such as streams and the sea. Many innocent animals are homeless and wandering around. Some people died of hunger and cold. Can humans bear to see their homes destroyed? Do you just watch animals, rivers and other friends get hurt? Aren't you afraid that the earth will die one day and so will mankind? Although everyone knows how to protect the earth, how many people have done it and how many people have really realized this great plan?

People use electricity without restraint. We know that primary electricity can be used for steelmaking 1.5kg, coal mining 53kg, 16 inch electric fan can run 16 hour, 100 watt lamp can illuminate 100 hour, and 25 inch color TV can work100 hour. Saving 1 kwh of electricity can save 400 grams of standard coal and reduce the emission of sulfide and nitride into the atmosphere. Saving electricity can also reduce acid rain and slow down global warming.

We must also be extra careful when using electrical appliances. However, in real life, people often ignore security. Danger happens from time to time. Therefore, you can unplug the necessary electrical appliances after use, which is not only not easy to cause safety accidents, but also saves electricity, which is also a matter of killing two birds with one stone.

Therefore, we humans must protect the environment and save energy, science of electricity, protect our homeland!
