If we don't cherish our precious water source, the last drop of water on earth may well be our tears!
Water is one of the important resources for human survival and development, is indispensable, irreplaceable special resources, no water there is no life, there is no progress of civilization, economic development and social stability, the world's water resources are limited, economic and social development must be compatible with the water, can not be unlimited water extraction, can not exceed the carrying capacity of water development.
As everyone knows, China is a country with poor water resources, not to mention the shortage of water for agricultural irrigation and industry, and even the people's drinking water for daily life has become a problem in many places. In every drought year, water shortage is unavoidable, so water conservation has become a major issue related to the national economy and people's livelihood. It can be seen that the problem of water conservation is not only to enhance people's awareness of water conservation and change some living habits, but also to promote science and technology to save water, and to use science and technology, the primary productive force, to develop more water-saving appliances with high scientific and technological content, and to improve the effective utilization rate of water resources, so that our water-saving problem can be solved to a certain extent.
Saving water means not only shrinking life, but also cultivating a new ethics of water use. The introduction of some water-saving technologies shows that water conservation is becoming a social behavior. Water nurtures and sustains all life on Earth, and human society cannot exist without water.
The effective way to protect water resources is to save and rationally use water, reduce water waste and control water pollution, plant trees, and prevent soil erosion. In the long run, it is necessary to try to desalinate seawater in the most economical way and expand the freshwater supply. It can be said that through years of efforts, China's water-saving cause has made great progress and progress, but compared with some developed countries, there is still a distance.
The middle of this century is a period when China is making every effort to achieve the grand goal of socialist modernization; with population growth and social and economic development, water consumption will increase by a large margin, and the contradiction between supply and demand of water resources will become more acute; only by adhering to the principle of simultaneously opening up sources and reducing expenditures, and putting water conservation in the first place, further intensifying water-saving work, realizing the optimal allocation and efficient utilization of water resources centered on water conservation, and striving to achieve a basic balance between supply and demand, can we successfully achieve the long-term economic development goal.
Saving water and ensuring the sustainable use of water resources is our common cause, and it is our common responsibility.

Water, the source of life, the hope of the survival of all things in the world, the cradle of human civilization! Every river on the earth is the mother of mankind, it is she who nourishes us with sweet milk, and it is she who pushes human civilization to glory again and again with selfless dedication! In the face of such a great blessing as the Mother River, human beings have carried out crazy aggression against her because of selfishness and greed, leaving her scarred and unrecognizable.
I could hear her crying sadly. Let us join hands and work together to maintain the health of our mother river with our wise hands, and return the clear and beautiful demeanor of the mother river, so that the mother river will always laugh! Make our hometown a better tomorrow!
Water is the source of life, and we need to protect every drop of water. It is true that without water, the earth would dry up; If there is no water, we humans can die of thirst; If there was no water, there would be no beautiful world. Water is one of the important resources for human survival and development, and it is an indispensable and irreplaceable special resource.
Without water, there is no life, and there is no progress in civilization. We must cherish every drop of water and every tear of Mother Earth. Let's protect our planet!!
Water is both a renewable and non-renewable resource.
This does not need to be specified, to improve the utilization rate of water resources, we must first rely on conservation! Saving is not a means, but a kind of consciousness, habit, should be deeply rooted in everyone's heart! Only when all people have this awareness will water resources not be wasted for no reason!
Of course, saving requires a lot of means, methods and some technical support. The second is the mature application of water treatment technology, and freshwater resources are very scarce! Seawater can be desalinated!
But the cost is still very high! The application of sewage treatment technology is not extensive enough and the technology is not mature enough! So that the utilization rate of sewage is very low!
And the quality of the product water is not effectively guaranteed! Therefore, at present, only by saving and improving the progress of technology can we make better use of water resources! May our children and grandchildren not be distressed by water.
