The earth's water resources are vital to people and ecosystems ‌. Water is the source of life, whether it is drinking water, agricultural irrigation or industrial production, water plays an irreplaceable role. About 70% of the earth's surface is covered by water, but fresh water resources available for human use account for only 2.5% of the total water on the planet, and are unevenly distributed, which makes water especially precious ‌.

Importance of water resources

Survival needs ‌ : water is an integral part of human needs and participates in various physiological activities of the human body. Not getting enough water can lead to health problems and even life-threatening ‌.

Agricultural irrigation ‌ : water is the cornerstone of agricultural production. Without enough water resources, crops could not grow and food security would be threatened ‌.

Industrial production ‌ : water also plays an important role in industrial production, and many production processes require the participation of water. Lack of water resources affects the efficiency and cost of industrial production ‌.

‌ ecosystem balance ‌ : Water is an important part of the ecosystem, maintaining its balance and diversity. Lack of water resources can lead to the collapse of ecosystems and affect biodiversity ‌.
