The total volume of water on the earth is about 1,386 million cubic meters, of which it is distributed in the oceans, and the freshwater is only about 3,500 kilometers cubic meters. If you deduct the amount of water distributed in unreachable glaciers and ice caps on high mountain tops, as well as in saline lakes and inland seas, the amount of water in lakes and rivers on land is less than 1% of the total water on Earth.
It does not make sense to consider only the amount of water resources alone, it must be combined with the local socio-economic production conditions, and it must be combined with the quality of water resources to have its social significance. The treatment and conservation of industrial water depends on the state. Household water depends on everyone...

Water is the source of life, as the saying goes"A person can go a day without eating, but not a day without drinking water"Human life is inseparable from water, and water is an indispensable and important resource for human life.
Globally, 1.1 billion people lack access to safe drinking water, and more than 5 million people die each year from water-related diseases. It is estimated that 12 million people will die from water pollution and water scarcity in the world this year. Drinking contaminated water is one of the main causes of illness and even infection in humans.
Diseases caused by simply drinking unsafe water and lack of sanitary water kill more than 5 million people each year.
According to relevant data from international organizations, the number of "environmental refugees" that accompanied the water resources in river basins reached 25 million in 1998, surpassing the number of "war refugees" for the first time.
The United Nations World Assessment of Water estimates that by mid-century, nearly 7 billion people in 60 countries will face water scarcity, based on the standard of less than 1,000 cubic metres of water per capita per year, compared to less than 500 cubic metres per capita in China in the future. China will be a country with serious water shortages for a long period of time.
However, in our lives, the waste of water resources is quite serious...From the data we have investigated, it is clear that in our real life, in our surroundings, the waste of water is alarming...Let's talk about our school first, we have noticed that sometimes the tap in the school building is broken, and the water is constantly flowing.
Some faucets often drip out drop by drop, and many families seem to be saving water on the surface, but they are actually wasting water resources. In some homes, water from faucets in kitchens and bathrooms drip into tanks and buckets all day long, but the water from tanks and buckets keeps flowing down the drain. Some families put some completely usable water, such as water for washing vegetables and washing faces, directly into the sewer basin by basin.
As you can imagine, the amount of water that doesn't drip every year, and the amount of water that is wasted in our lives, is really incalculable, and if you want to calculate it carefully, the result will definitely leave you stunned!
While we are wasting water, we are also polluting our water sources, some cities and towns are directly discharging domestic polluted water and industrial wastewater into rivers, and some are selling garbage and dead livestock and throwing them into rivers, so that the river water can no longer provide convenience for human beings.
Everyone saves water, cherishes and protects water resources, and gives us a green tree. Flowers. The river is clear. Let's have a beautiful living environment for fish!

Engel's coefficient (ENGEL's coefficient) is the share of total food expenditure to total personal consumption expenditure. In the 19th century, the German statistician Engel drew a law on the changes in consumption structure based on statistical data: the less a household income, the greater the proportion of household income (or total expenditure) spent on food, and as the household income increases, the proportion of household income (or total expenditure) spent on food will decrease. >>>More
