Saving water is proud-don't let water run at any time.
China is one of 13 water-poor countries in the world, and its fresh water resources are less than 1/4 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 654.38+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. If detergent remains on clothes, it will cause allergic dermatitis to 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 panel 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 particulate matter 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% in the primary 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-everyone uses energy-saving lamps.
"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 for the construction of bicycle lanes when roads are being built. 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! Consuming a lot 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 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.
