No
If, total water available on earth is 100%, then 97.5% is salty water and 2.5% is fresh water but from that 2.5%, only 1.2% is portable as very large amount of fresh water is stored as glaciers.
So, there is only a few amount of water for human use. Therefore, we all should save water and use it properly.
