Though most of the Earth is covered with water, it is far to saline to be fit for consumption for us humans. Salty water in oceans, seas etc. constitute 97% of the total water on Earth.
Of the remaining 3%, 2% is locked away in ice caps and glaciers. The last 1% is what all humans have to make ends meet. The increase of population resulted in a high demand in water, and the unequal distribution of this water also contributed to the scarcity of water.
Hope it helped. If it did, please mark it as the brainliest answer!

Because Earth has 71% water but only 2.5% is usable in which 70% is glaciers and iceburgs and 30% river ,lakes etc . And we use these 30% water bodies and these gets polluted .
