The annual water saving day is from March 22nd to March 28th. Its significance lies in telling people the importance of saving water.
The earth's water reserves are very rich, * * * as much as145 billion cubic kilometers. However, seawater accounts for 97.2%, land fresh water only accounts for 2.8%, and fresh water such as rivers, freshwater lakes and shallow groundwater, which are closest to human life, only accounts for 0.34% of fresh water reserves. What is even more worrying is that this extremely limited fresh water is being polluted more and more. According to scientific estimates, more than half of the countries and regions in the world lack drinking water, especially in the economically underdeveloped third world countries. At present, 70% of people, that is, 654.38+0.7 billion people, do not have access to clean water, and nearly 80% of the world's population is threatened by water shortage. China's per capita fresh water quantity is a quarter of the world's per capita level, and it belongs to a water-deficient country. More than 300 cities in China are short of water, and 29% people are drinking bad water, among which 70 million people are drinking high fluorine water. Every year, the economic losses caused by water shortage reach more than 654.38+0 billion yuan, and the economic losses caused by water pollution reach more than 40 billion yuan.
Terrible data show that water shortage has become a major crisis facing the world today. Therefore, it is an urgent task for governments all over the world to protect and utilize water resources more effectively and reasonably. So, how can we protect and rationally use water resources more effectively? From the environmental point of view, the most perfect measures are water interception and water transfer. Change the temporal and spatial distribution of water resources. But this is only one aspect. For human beings, it is more important to pay attention to saving water and improving the utilization rate of water resources: advocating water-saving industries in industry, controlling pollutant discharge and strengthening wastewater treatment; Advanced irrigation methods (sprinkler irrigation and drip irrigation) should be adopted in agriculture. Water is the foundation of life, which not only relates to the quality of human life, but also affects human survival ability. Therefore, it is extremely urgent to enhance water crisis awareness, cherish water, save water and protect water resources.
Therefore, China has formulated corresponding water-saving measures.
The Ministry of Construction of China decided to take the second week of June every year as the national publicity week for urban water conservation, with the aim of conscientiously implementing the Water Law of People's Republic of China (PRC) and the Regulations on Urban Water Conservation of the State Council, and enhancing people's planning and water-saving concepts.
How to save water? There are the following methods:
1, water-saving pride-turn off the tap at any time.
2, a multi-purpose water-make full use of every drop of water
3. Stop dripping-check and repair the faucet
4. Protect the water source-protecting the water source means protecting life.
5. Use less detergent-reduce water pollution
6, afforestation-water conservation
7, active publicity-let everyone into the "battle" of water saving.
Of course, this is far from enough, but everyone can do these methods.
We all want to live in a world where birds are singing and flowers are fragrant, and water is the need of everything. So let's protect the whole earth and the whole world from now on. Save water resources and protect the world!
Save water resources and protect the world
March 22nd to March 28th every year is the Day of Saving Water, which tells people the importance of saving water.
The earth's reservoir water is very rich, with 1.45 billion cubic meters. However, seawater accounts for 97.2%, land only accounts for 2.8% of fresh water, and fresh water such as the surface and rivers, freshwater lakes and shallow groundwater that are closest to human life only accounts for 0.34% of fresh water reserves. What is even more worrying is that a very limited amount of fresh water is being polluted day by day. According to scientific estimates, more than half of the countries and regions in the world are short of drinking water, especially in the economically underdeveloped third world countries. At present, 70% of the people, that is,170,000, cannot drink clean water, and nearly 80% of the world's population lives on water.
Threats. China's per capita fresh water is one quarter of the world average, and it is a water-deficient country. More than 300 cities in China are short of water, and 29% people are drinking inferior water, among which 70 million people are drinking high fluorine water. Every year, the economic losses caused by water shortage amount to more than10 billion yuan, and the economic losses caused by water pollution exceed 400 million yuan.
Terrible data show that water shortage has become a major crisis facing the world today. Therefore, it is an urgent task for governments all over the world to protect and utilize water resources more effectively. So, how can we protect and rationally use water resources more effectively? From the environmental point of view, the most complete and effective measure is to draw water to make water. Changes of temporal and spatial distribution of water resources. But this is only one aspect. For human beings, it is more important to pay attention to saving water and improving the utilization rate of water resources: promoting industrial water saving in industrial sectors, controlling pollutant emissions and strengthening wastewater treatment; Should be adopted in agriculture.
Use advanced irrigation methods (sprinkler irrigation, drip irrigation) and so on. Water is the foundation of life, which is not only related to the quality of human life, but also affects human survival. Therefore, it is imperative to strengthen the awareness of water crisis, cherish water resources, save water and protect water resources.
Therefore, China has formulated corresponding water-saving measures.
The Ministry of Construction of China decided to save water in cities in the second week of June every year as part of the national publicity week, aiming at conscientiously implementing the "People's Republic of China (PRC) Water Law" and the State Council's "Urban Water Conservation Management" in order to improve the concept of water planning and water conservation.
How to save water? There are several ways:
1, the pride of saving water-turn off the tap.
2, a multi-purpose water-make full use of every drop of water
