Why does India lack water on a large scale, but it doesn't take water from the Ganges for drinking?

India uses Ganges water as drinking water. It's not that they didn't expect it Because of the long-term water shortage, even the dirty water like Ganges water, they have the choice to drink. Otherwise, if only pure groundwater is used, it is difficult for them to survive.

Indian natives are especially devout to the Ganges River, which they consider to be their best wealth. Contrary to us, we purify the water before drinking it, and then boil it to eliminate bacteria in the water before drinking it. But Indian natives are not like this. They drink Ganges water directly without any treatment.

Because they drink Ganges water for a long time, their bodies will have some antibodies. After all, the Ganges water is not clean because of the pollution of garbage and the corruption of corpses. India's water resources are particularly scarce, and India is dominated by agriculture. Agricultural farming needs a lot of water to irrigate the land. Even if India grows drought-tolerant plants, it needs water for irrigation. If the Ganges water is not used, these crops will be difficult to survive.

Because Indians over-exploit groundwater, the groundwater level drops, and it takes hundreds of meters to re-drill a well. Instead of spending a lot of manpower and material resources to exploit groundwater, it is better to drink dirty water locally. Some people are worried about the health of Indians. They think that the water in Ganges should be filtered before drinking, but because the water pollution in Ganges is very serious, if it is used to purify the water source, the cost of purification is also very high.

Not getting sick after drinking Ganges water is also related to their diet, because they eat some foods that can inhibit bacteria, so drinking Ganges water into their stomachs will not have a great impact on their health. From this point of view, India is short of water on such a large scale, and they will also use Ganges water to drink.
