The planet's fresh water resources represent approximately 2.5% of total water.
The reason why the ratio of freshwater resources to total water volume is so low has to do with factors such as the history, geography and climate of Earth. First, most of the Earth's surface is covered by oceans, making most of Earth's water salty. Second, the Earth's climate and geographic location will also affect the distribution of water resources. For example, some regions have drier climates and less precipitation, so they have relatively fewer freshwater resources.
However, freshwater resources are vital for the survival of humans and other organisms. Fresh water is an important resource for human consumption, agricultural irrigation, industrial production and the maintenance of ecosystems. He isIt is therefore crucial to protect and rationally use fresh water resources.
In order to protect fresh water resources, we must take a series of measures, including saving water, reducing water pollution, developing new water resources, and strengthening resource management in water. In addition, we should also improve public understanding and awareness of freshwater resources and promote the joint efforts of the whole society to protect and utilize freshwater resources.
Uses of fresh water resources on the planet:
1. Fresh water resources are the source of human life. Whether for drinking, washing, irrigating agriculture or industrial production, fresh water is essential. Especially early in human life, people relied primarily on freshwater resources such as rivers, lakes, and groundwater tour meet their basic vital needs.
2. Fresh water resources are crucial for the development of agriculture and fisheries. Crops need fresh water for irrigation, and fisheries also need fresh water to maintain ecological balance. Freshwater can also provide a suitable environment for animals and plants to grow and reproduce, and plays an important role in maintaining ecosystem stability.
3. Fresh water resources are also one of the main raw materials for industrial production. Many industrial production processes require large amounts of fresh water, such as textile, food, chemical and other industries. At the same time, fresh water can also be used for power generation, transportation and various other public services.
4. Fresh water resources also have diving valueroasting and tourism. Many lakes, rivers, waterfalls and other freshwater landscapes attract a large number of tourists to watch and play. People can go boating, fishing, swimming, etc. in these places and enjoy the pleasure brought by fresh water.
