Code of conduct for citizens to protect water resources

Concept: save water and be proud.

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. Strengthen the legal construction and publicity work of protecting water resources and saving water, enhance the awareness of saving water of the whole people, make people consciously realize that water is a valuable resource, abandon the outdated concept of "inexhaustible", and a good social fashion of cherishing, saving and protecting water resources has taken shape.

Protection of water sources

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.

Multi-purpose of one water

It can reuse water resources, improve the utilization rate and help to save water.

Use detergent carefully.

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. 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 15%, more than 70 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 domestic sewage exceeds 50% 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 make the creatures in the water die due to lack of oxygen. Therefore, water has become stagnant water and smelly water.

Cherish paper

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).

Increase forest area and save water.

Forests have the functions of conserving and absorbing water sources, reducing ineffective evaporation, and regulating microclimate, which is of throttling significance. It can increase the precipitation in forest areas and forest edges, which is of open source significance.
