As a child, who hasn’t fallen in love – three parts of the earth is water, and one part is land. So if you actually calculate the ratio of water and land, it will be close to this. 71 percent of the Earth’s surface is covered by water. The rest is land. How much of this huge amount of water can people use?
If you think about it, it may seem like the whole thing, or not? The answer is no. National Geographic reports that the ice cover is already falling away. Apart from this, salt water is more.
As a result, only two and a half percent of the world’s total water is usable by humans. But people do not reach even that.
Only 1 percent of the world’s water is within human reach. Scientists no longer say that if there is another world war, it will be over water.
