But 98% of water is sea water and it's too salty for us to use. Moreover, since most of this remaining 2% freshwater is ice, less than 0.3% of water on Earth is directly available to us. But our precious water is getting dirty. Now, let's see how much our life depends on water and how we can keep our water clean and safe.
