Water in daily life has the following six main functions:
1. Meet human daily water needs
2. Provide plants with enough water< p>3. Ensure cleaning of clothing and supplies
4. Ensure the survival and reproduction of animals
5. Use water resources to generate electricity
6. Make water entertainment facilities< /p>
For humans, water in daily life is mainly used to maintain water life and provide resources.
1. Water is the source of life
Water is an important component of dietary fiber, an essential substance for all life and plays an important role in life activities. The body's sources of water include drinking water, water from food, and water produced by body metabolism. Water is an important element in the human body, making up approximately 60-70% of the body's body.body ds of a healthy adult. The water content of the human body varies with age and gender.
Generally speaking, healthy adults need around 2,500 ml of water each day. In mild climatic conditions, adults engaging in light physical activity should drink at least 1,200 ml of water per day. Under conditions of high temperature or intense physical work, drinking water should be increased appropriately.
2. Water is the cradle of civilization
Water is not only necessary to sustain all life on earth, but is also of vital importance to all social and economic sectors. The world's major cradles of civilization mostly emerged and developed in large river basins rich in water resources. In modern times, thanks to scientific and technological advancements, humans have alleviated the problem of spatial distribution anduneven temporal distribution of water resources by constructing inter-basin water diversion projects and large-scale water storage projects, thereby significantly expanding the space for human survival and development.
The main users of water resources are domestic water, industrial water and agricultural water. China's South-to-North Water Diversion Project alleviates the problem of uneven regional water distribution by changing the water flow path.
As we face a global water crisis, we must increase water circulation, reduce water consumption and improve water recycling to save water in our daily lives.
