Features: Water is the source of life, and all living beings on Earth cannot do without it. Earth has become a home for humans because it has the natural conditions necessary for human survival and development, and water is one of the most important of these natural conditions. Looking at our home, Earth, from space, we see a beautiful blue planet almost entirely covered by water. More accurately, Earth should be called a water planet, because the area of the oceans accounts for about 71% of the Earth's surface. If all the water in the oceans were evenly distributed over the Earth's surface, it would form a water layer with a thickness of 2,700 meters. It is because of this abundant water that billions of humans and tens of millions of species have been able to thrive. Water is extremely closely related to humans—it not only meets the growing needs of human life and production but also maintains the natural ecosystems that sustain life. Therefore, water is the most important material basis for human survival and sustainable development, an irreplaceable resource.
