1. Be proud of saving water-turn off the tap at any time and don't let the water run empty

China is one of the 12 water-poor countries in the world, and the fresh water resources are less than 1.4 of the world's per capita water. More than half of the more than 611 cities in China are short of water, of which 118 cities are seriously short of water. The scarcity of surface water resources leads to excessive exploitation of groundwater. In the 1951s, wells in Beijing could pump water about 5 meters below the surface. Now, the average depth of 41,111 wells in Beijing is 49 meters, and the groundwater resources are almost exhausted.

2. Guarding the water source-protecting the water source means protecting life

According to environmental monitoring, about hundreds of millions of tons of sewage are directly discharged into water bodies every day in China. More than half of the seven major water systems in China are polluted. Of the 35 key lakes, 17 are seriously polluted, and 1/3 of the country's water bodies are not suitable for irrigation. More than 91% of urban waters are seriously polluted, more than 51% of urban water sources do not meet drinking water standards, 41% of water sources are no longer drinkable, and 61%-71% of the total water shortage in southern cities is caused by water pollution.

3. Multi-use of one water-reuse of water

71% of the earth's surface is covered with water, with about 1.4 billion cubic meters of water, of which 96.5% is seawater. Although the rest is fresh water, more than half of it is ice, rivers and lakes and other water resources that can be directly used, accounting for only about 1.113% of the total water.

4. Stop dripping-check and repair the faucet

5. Use detergent carefully-use soap as much as possible to reduce water pollution

Most detergents are chemical products, and a large amount of wastewater with high detergent content will be discharged into rivers, which will worsen the water quality. Improper use of detergents for a long time will damage people's central system, hinder people's intellectual development, reduce their thinking ability and analytical ability, and even cause mental disorders. Detergent residue on clothes will stimulate allergic dermatitis on the skin. If the detergent with high concentration is used for a long time, carcinogens in the detergent will enter the human body from the skin and mouth, which will damage health.

6. Care about the air quality-don't forget that you are breathing all the time

The monitoring results of the Global Atmospheric Monitoring Network show that the daily average concentration of total suspended particulate matter in the atmosphere of Beijing, Shenyang, Xi 'an, Shanghai and Guangzhou is 211-511 micrograms per cubic meter, which is 3-9 times higher than the standard of the World Health Organization and is listed among the top ten polluted cities in the world.

7. Turn off the lights at will-save electricity and avoid pollution

China is a country where thermal power generation is the main energy source and coal is the main energy source. Coal accounts for more than 71% of the disposable energy structure. If it is developed in the conventional way, to reach the level of developed countries, it needs at least 11 billion tons of coal as energy consumption, which will be equivalent to the sum of global energy consumption. When coal is burned, it will release a lot of harmful gases, seriously pollute the atmosphere, form acid rain and cause greenhouse effect.

8. Save electrical appliances-contribute to slowing down the global warming

A large number of coal, natural gas and petroleum fuels are used in industry, commerce, housing and transportation. The excessive carbon dioxide generated when these fuels are burned is like a glass cover, which blocks the ground heat from radiating to outer space, leaving hot air in the atmosphere, forming a "greenhouse effect", which makes the global weather change and produces catastrophic drought. Scientists estimate that if the trend of climate warming continues, low-lying areas such as Bengal, Holland, Egypt, China and some island countries will be in danger of being swallowed up by seawater.

9. Reduce air conditioning-reduce energy consumption

When burning fuels such as coal, oxides of carbon and nitrogen are discharged in the form of gas. These oxides combine with water vapor in the air to form highly corrosive sulfuric acid and nitric acid, and then fall back to the ground together with rain, snow and fog, which is called "death in the air" acid rain. There are three major acid rain areas in the world: the United States and Canada, northern Europe and southern China. Acid rain can not only strongly corrode buildings, but also acidify soil, resulting in trees dying, crop yield reduction, lake water becoming sour, and fish and shrimp dying. Due to the extensive use of coal fuel in China, the annual economic loss caused by acid rain pollution is about 21 billion yuan. The acidity of precipitation in acid rain areas in China is still rising and the area is still expanding.

11. Support green lighting-everyone uses energy-saving lamps

"China Green Lighting Project" is one of the key energy-saving projects in China. According to the implementation plan of the project, energy-saving and efficient lighting lamps will be promoted throughout the country during the Ninth Five-Year Plan period. By the year 2111, we will strive to save 22 billion kWh of lighting electricity, save corresponding coal burning in power plants, and reduce the emissions of sulfur dioxide, nitrogen oxides, dust, ash and carbon dioxide. 11. Use renewable resources-don't wait until the day when energy is exhausted

91% of the energy currently used by human beings is oil, natural gas and coal. The formation process of these fuels takes hundreds of millions of years and is a non-renewable resource. Solar energy, wind energy, tidal energy and geothermal energy are renewable and are called renewable energy. People call those energy sources that do not pollute the environment "clean energy".

12. Be a "bus family"-be proud of taking public buses.

There are nearly 1.2 million motor vehicles in Beijing, the capital of China, which is only 1.6 of that in Tokyo and new york. However, the concentration of pollutants emitted by each vehicle is 3-11 times higher than that of similar foreign motor vehicles. 73% of hydrocarbons, 63% of carbon monoxide and 37% of nitrogen oxides in Beijing's atmosphere come from motor vehicle emissions.

13. Being a "cycling hero"-protecting the atmosphere begins with the first step

In Europe, many people are willing to go to work by bike in order to reduce the air pollution caused by driving, and such people are respected as environmental defenders. American newspapers often mobilize people to buy as many necessities as possible when shopping in supermarkets, so as to save gasoline and reduce air pollution. The influential American Bicycle Association has been calling on the government to build bicycle lanes when building roads. In Germany, many families like to go out in the same car with their neighbors to reduce the emission of automobile exhaust. In order to clean the air in the city, Tehran, the capital of Iran, has set a "selfless car day". On this day, the Iranian president also goes to work by bus with the citizens. In Shanghai, China, some company employees often share a taxi, which is called "fight".

14. Reducing tail gas emission-the responsibility of drivers

The Law of the People's Republic of China on the Prevention and Control of Air Pollution stipulates that motor vehicles and ships shall not discharge pollutants into the atmosphere in excess of the prescribed emission standards, and control measures shall be taken for motor vehicles and ships that exceed the prescribed emission standards. Vehicles that discharge pollutants in excess of the national emission standards shall not be manufactured, sold or imported.

15. Use unleaded gasoline-driver's choice

Cars that use leaded gasoline will emit lead through exhaust gas. These lead particles will harm people's nervous system and accumulate in people's bones after entering the human body with breathing; If it falls into soil or rivers, it will be absorbed by various animals and plants and enter the human food chain. Lead accumulated in the human body to a certain extent will cause anemia, hepatitis, pneumonia, emphysema, angina pectoris, neurasthenia and other diseases.

16. Cherish paper-that is, cherish forests and rivers

The surge in paper demand is one of the reasons for the increase in wood consumption. The annual consumption of wood for papermaking in China is 11 million cubic meters, with more than 1.3 million tons of imported wood pulp and more than 4 million tons of imported paper. How many trees will be cut down! The large consumption of paper not only causes forest destruction, but also seriously pollutes rivers and lakes due to the sewage discharged from pulp production (the pollution caused by the paper industry accounts for more than 31% of the total water pollution).

17. Use recycled paper-reduce deforestation

China's forest coverage rate is only 1/4 of the world average. According to statistics, China's forests decreased sharply by 23% in 2111, and the felling stock decreased by 51%. Since the 1951s, the natural forests in Xishuangbanna, Yunnan Province have disappeared at a rate of about 6,111 hectares every year. At that time, 55% of the original forest coverage area has now been reduced by half.

18. Replacing New Year cards-reducing the burden on the earth

In recent years, Japanese people with various manners are also changing the habit of giving a large number of New Year cards. Some big companies advertise that they will no longer send greeting cards by post. College students in our country organized the activity of "saving cards to save trees", advocating saving money for buying greeting cards to plant trees and protect nature.

19. The new fashion of saving grain-turning frugality into glory

China has more than 31 million hectares of cultivated land, accounting for 7% of the world's cultivated land. The per capita arable land is less than 47% of the world average, and the per capita arable land in more than 611 counties (districts) in the east is lower than the warning line of 1.15 hectares determined by FAO.

21. control noise pollution-let's supervise each other

noise will interfere with the normal life of residents and damage people's hearing. Noise has obvious influence on human nervous system and cardiac engineering vascular system. People who have been exposed to noise for a long time will have symptoms such as headache, brain swelling, palpitation, memory loss and fatigue. Low-frequency noise makes people feel chest tightness and nausea. Noise can also affect the digestive system, which can lead to coronary heart disease and arteriosclerosis.

21. Maintain a peaceful environment-let's start from ourselves

Germany stipulates that when using audio equipment indoors, the volume should be loud enough to be heard indoors. American law stipulates that noise courses should be set up in schools. According to British regulations, audio equipment is not allowed for advertising, entertainment and business activities, and it is not allowed to be used in public places at night. Japan stipulates that it is necessary to control the noise generated by night operation in catering industry and the noise generated by publicity with audio equipment; Vehicles shall not produce unnecessary noise that affects others, and unnecessary idling of vehicles is prohibited.

22. Recognize "environmental label"-choose and buy green food

The environmental protection products that have been certified by China Green Label Certification Committee include low-fluorine household refrigeration appliances, fluoride-free mousse and styling hair gel, unleaded gasoline, cadmium-free mercury-lead rechargeable batteries, phosphorus-free fabric detergents, low-noise washing machines and energy-saving fluorescent lamps. These environmental label products are labeled with "China Environmental Label". The central structure of the logo is green hills, green waters and the sun, which represents the environment on which human beings depend. The 11 rings on the periphery indicate the public's participation in protecting the environment.

23. Use fluorine-free products-protect the ozone layer

The ozone layer can absorb ultraviolet rays and protect people, animals and plants from harm. Chlorine atoms in freon have a great destructive effect on the ozone layer, which can decompose ozone that absorbs ultraviolet rays and make the ozone layer thinner. Intense ultraviolet radiation will damage the immune function of people and animals, induce skin cancer and cataracts, and destroy the ecosystem on the earth. In 1994, people observed the largest hole of ozone house in Antarctica, with an area of 2,411 square kilometers. According to relevant data, crops have been damaged and animals in pasture have been blind in southern Chile, which is located on the edge of Antarctic ozone layer. The ozone layer over the Arctic is also thinning. At present, 24 developed countries that first used CFCs (freon is a kind of CFC substance) have signed the Montreal Protocol to restrict the use of CFCs, and the amendment in 1991 set the time for developed countries to ban the use of CFCs at 2111. In February, 1993, the government of China approved the "China Ozone Depleting Substances Phase-out Program", which determined that ozone depleting substances would be completely phased out in 2111.

24. Choose phosphorus-free washing powder-protect rivers and lakes

Most washing powders produced in China contain phosphorus. The annual output of washing powder in China is 2 million tons. According to the average phosphorus content of 1.5%, more than 71 thousand tons of phosphorus are discharged into surface water every year, which has a great impact on rivers and lakes. According to the investigation, the total phosphorus levels in Dianchi Lake, Erhai Lake and Xuanwu Lake are quite high, and the phosphorus brought by washing powder in Kunming's domestic sewage exceeds 51% of the total phosphorus load. After a large amount of phosphorus-containing sewage enters the water source, it will cause algae to grow wildly in the water, make the water eutrophication, reduce the oxygen content in the water, and kill the creatures in the water due to lack of oxygen. Water has thus become stagnant water and smelly water.

25. Buy environmentally-friendly batteries-to prevent mercury and cadmium pollution

The batteries we use every day rely on chemical action, or in layman's terms, corrosion to generate electricity. And its corrosion contains a lot of heavy metal pollutants-cadmium, mercury, manganese and so on. When it is abandoned in nature, these toxic substances will slowly overflow from the battery, enter the soil or water source, and then enter the human food chain through crops. These toxic substances will accumulate in the human body for a long time and are difficult to eliminate, damaging the nervous system, hematopoietic function, kidneys and bones, and some can cause cancer. Batteries can be said to be how much they are produced and how much they are discarded; Centralized production and decentralized pollution; Short-term use, long-term pollution

26. Choose green packaging-reduce garbage disaster

The weight of garbage thrown away per person every day is five or six times more than the average weight of human body. The annual output of garbage in Beijing is 4.3 million tons, and the daily output is 2,111 tons. The average person throws out about 1 kilograms of garbage every day, which is equivalent to piling up two Jingshan mountains every year. At present, the amount of garbage produced in China is four times that in 1989, and a large part of it is caused by excessive packaging. The packaging cost of many commodities, especially cosmetics and health products, has accounted for 31%-51% of the cost. Over-packaging not only causes great waste, but also increases the economic burden of consumers. At the same time, it also increases the amount of garbage and pollutes the environment.

27. Recognize the signs of green food-protect your own health

At present, there are more than 311 green food production enterprises in China, and more than 711 kinds of green food have been developed and produced according to the standards of green food. The products involve drinks, sprinkles, fruits, dairy products, cereals, aquaculture and other food categories. Other green foods, such as whole wheat bread, fresh whole grains, beans and mushrooms, are also very beneficial to human health.

28. Buy pollution-free food-maintain ecological environment

Food pollution sources: First, industrial waste pollutes farmland, water source and atmosphere, leading to the accumulation of harmful substances in agricultural products; Second, chemical fertilizers and pesticides remain in agricultural products; Third, some chemical pigments and additives are not properly used in food processing; The fourth is microbial pollution caused by improper storage and processing. After several years, pesticides on fruits and vegetables invade the human body, which will be manifested through the disorder of cancer and immune system, hormone secretion system and reproductive system.

29. Use less disposable products-save the earth's resources

Those "disposable" plastic bags not only cause a huge waste of resources, but also increase the amount of garbage. China's annual plastic waste is more than 1 million tons. If Beijing consumes one plastic bag per person every day, each bag weighs 4 grams, 4.4 grams of polyethylene film will be thrown away every day, and nearly 41,111 yuan will be thrown away for raw materials alone. If these plastics are spread out, the area of plastic film discarded by each person every year will reach 241 square meters, and the plastic bags discarded by the millions of people in Beijing every year will be twice the area of urban construction.

31. Bring your own shopping bags-use less plastic bags

In Germany, plastic bags are not provided free of charge in many supermarkets, in order to reduce the use of plastic bags. When many Germans buy things, they are used to carrying cloth bags or loading the goods directly into the car without plastic bags. Some housewives go shopping with huge rattan baskets in their arms in order to use less plastic bags. German hotels do not provide disposable toothbrushes, toothpaste, combs and slippers. Stainless steel knives and forks are used in restaurants and reused after high temperature disinfection.
