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

China is one of 12 water-deficient countries in the world, and its fresh water resources are less than14 of the world's per capita water. More than half of the more than 600 cities in China are short of water, among which 108 cities are seriously short of water. The scarcity of surface water resources leads to over-exploitation of groundwater. In the 1950s, wells in Beijing could pump water from 5 meters underground. Now the average depth of 40,000 wells in Beijing is 49 meters, and the groundwater resources are almost exhausted.

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

According to environmental monitoring, about 654.38 billion tons of sewage is directly discharged into water bodies every day in China. More than half of China's seven major water systems are polluted. Of the 35 key lakes, 17 are seriously polluted, and13 of the water bodies in China are not suitable for irrigation. More than 90% of urban waters are seriously polluted, more than 50% of urban water sources do not meet drinking water standards, 40% of water sources are no longer drinkable, and 60%-70% of the total water shortage in southern cities is caused by water pollution.

3. Multi-use of one water-let the water be reused.

70% of the earth's surface is covered with water, which is about 65.438+0.4 billion cubic meters, of which 96.5% is seawater. Although the rest is fresh water, more than half of it is water resources that can be directly used, such as ice, rivers and lakes, accounting for only about 0.003% of the total water.

4. Stop dripping-check and repair the faucet

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

Detergents are mostly 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 people's thinking ability and analytical ability, and even cause mental disorders. Detergent residue on clothes will irritate the skin and cause allergic dermatitis. 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 is harmful to health.

6. Care about air quality-don't forget that you have been breathing.

The monitoring results of the Global Atmospheric Monitoring Network show that the daily average concentration of total suspended particles in the atmosphere of Beijing, Shenyang, Xi, Shanghai and Guangzhou is 200-500 micrograms per cubic meter, which is 3-9 times higher than the standard of the World Health Organization, and is listed as one of the top ten polluted cities in the world.

7. Turn off the lights at will-save electricity for one time and cause less pollution.

China is a country with thermal power generation as the main energy source and coal as the main energy source. Coal accounts for more than 70% of the disposable energy structure. If it develops in the conventional way, it will need at least 654.38+000 billion tons of coal for energy consumption to reach the level of developed countries, which will be equivalent to the sum of global energy consumption. When coal burns, 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 global warming.

A large number of coal, natural gas and petroleum fuels are used in industry, commerce, housing and transportation. The excessive carbon dioxide produced when these fuels are burned is like a glass cover, which blocks the radiation of ground heat to outer space and leaves hot gas in the atmosphere, resulting in the "greenhouse effect", which makes the global meteorological variation, produces disastrous droughts and floods, melts icebergs in the North and South poles, and leads to the rise of sea level. 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

Fuels such as coal will release carbon and nitrogen oxides in gaseous form when burned. 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 with rain, snow and fog. This 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 South China. Acid rain can not only strongly corrode buildings, but also acidify the soil, resulting in the death of trees, the reduction of crop production, the acidification of lake water and the death of fish and shrimp. Due to the extensive use of coal fuel in China, the annual economic loss caused by acid rain pollution is about 20 billion yuan. The acidity of precipitation in acid rain area of China is still rising, and the area is still expanding.

10. Support green lighting-energy-saving lamps for everyone [1]

"China Green Lighting Project" is one of the key points of energy saving in China. According to the implementation plan of the project, energy-saving and high-efficiency lighting lamps will be promoted throughout the country during the Ninth Five-Year Plan period. By the year 2000, we will strive to save 22 billion kWh of lighting electricity, save the corresponding coal burning in power plants, and reduce the emissions of sulfur dioxide, nitrogen oxides, dust, ash and carbon dioxide.

1 1. Use renewable resources-don't wait until the energy runs out.

90% of the energy currently used by mankind is oil, natural gas and coal. The formation of these fuels takes hundreds of millions of years, and they are non-renewable resources. 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 the bus.

There are nearly1.2000 motor vehicles in Beijing, the capital of China, only 1/6 in Tokyo and new york. However, the concentration of pollutants emitted by each vehicle is 3- 10 times higher than that of similar foreign vehicles. 73% of hydrocarbons, 63% of carbon monoxide and 37% of nitrogen oxides in Beijing's atmosphere come from motor vehicle emissions.

13. be a "riding hero"-protect the atmosphere from one step.

In Europe, in order to reduce air pollution caused by driving, many people are willing to go to work by bike. Such people are respected as environmental defenders. American newspapers often mobilize people to buy as many necessities as possible when shopping in supermarkets 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 purify the urban air, the Iranian capital Tehran has set up a "selfless car-free day". On this day, the Iranian president also went to work by bus with the citizens. In China and Shanghai, employees of some companies often share a taxi, which is called "fighting".

14. Reducing exhaust emissions-the responsibility of drivers

The Law of People's Republic of China (PRC) on the Prevention and Control of Air Pollution stipulates that motor vehicles and ships shall not discharge pollutants into the atmosphere beyond the prescribed emission standards, and control measures shall be taken for motor vehicles and ships that exceed the prescribed emission standards. Vehicles with pollutant emissions exceeding 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. After these lead particles enter the human body with breathing, they will harm the human nervous system and accumulate in human bones. If it falls into soil or rivers, it will be absorbed by various animals and plants and enter the human food chain. Lead accumulation 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 soaring demand for paper is one of the reasons for the increase in wood consumption. The annual consumption of wood for papermaking in China is100000 cubic meters, including 65438+300000 tons of imported wood pulp and 4 million tons of imported paper. How many trees will be cut down! The large consumption of paper not only causes the destruction of forests, but also seriously pollutes rivers and lakes because of the sewage discharged from pulp production (the pollution caused by paper industry accounts for more than 30% of the total water pollution).

17. Use recycled paper-reduce deforestation

The forest coverage rate in China is only 1/4 of the world average. According to statistics, the forest in China decreased by 23% during the period of 10, and the logging volume decreased by 50%. Since 1950s, the natural forests in Xishuangbanna, Yunnan Province have disappeared at a rate of about10.6 million hectares per year. At that time, 55% of the original forest coverage area has now been reduced by half.

18. replacing the new year card-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. Chinese college students organize the activity of "saving cards to save trees" and advocate saving money to buy greeting cards and plant trees to protect nature.

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

China has1.300 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 600 counties (districts) in the east is below the warning line of 0.05 hectares set by FAO.

20. 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, leading to coronary heart disease and arteriosclerosis. Can rainwater be reused?

With the development and application of science and technology, rainwater utilization will become one of the important ways to reuse water resources. Nanning is a hilly city, and this terrain is very conducive to rainwater collection. According to the terrain, a rainwater collection drainage pipe (ditch) and an underground rainwater collection pool are set up, so that the surface rainwater can be collected into the collection pool through the drainage pipe (ditch), and the rainwater purified by biological or sand filtration can be used for greening and road washing projects, which greatly saves water resources.

Can't you kill pests without chemical pesticides?

Everything in the world has existed since ancient times, and these phenomena have also been destroyed by man-made indiscriminate arrests and even ecological imbalances. Now environmental protection and biological experts have reintroduced the biological chain of natural ecological cycle into our lives. They suggested that the four pests could be eliminated by raising small animals according to the principle of mutual resistance of species. For example, raising family swallows to kill mosquitoes and pigeons to kill pests can not only avoid the harm of excessive use of chemical pesticides to the environment, but also increase the natural landscape around us and enhance the appreciation.

Do you know how to classify daily garbage?

The classified collection and recycling of garbage is undoubtedly a great measure for the whole people to protect the environment, but do you know how to classify daily garbage?

Environmental experts pointed out that daily life garbage can be divided into three categories:

The first category is toxic and harmful waste (such as waste batteries, etc.). );

The second category is degradable garbage such as organic garbage;

The third category is refractory garbage (such as plastic, metal, glass, etc. ).

After garbage classification, organic garbage can be used as fertilizer for flowers and trees after treatment, renewable garbage can be distributed to relevant departments for recycling, and the rest garbage can be packaged and sent to the municipal garbage management department for treatment. This is the truly effective and correct method of garbage classified collection and centralized treatment.

Does your faucet save water?

Water is an important condition for human survival, and saving water is the obligation of every citizen. With the enhancement of people's awareness of environmental protection, various water-saving appliances came into being. You may not know that small taps save water. In addition, there are low-capacity water-saving toilets and other products. These products help us save water and protect the ecological environment from the nuances of life-are you still unwilling to catch up with this trend?

Solar energy, how to use it?

Solar energy is a renewable energy developed by human beings using sunlight and heat. Now it is widely used in all fields of our lives. For example, as we all know, solar water heaters use the heat energy of the sun. In fact, solar energy can also be converted into electric energy, and the solar energy obtained by solar photovoltaic (PV) system can be used to supply power for lighting and ventilation systems, thus greatly reducing energy consumption.
