Water is one of the most precious things on Earth that helps produce life along with the combination of other Earth minerals and with those natural combination elements mankind has to do his/her job in making sure those great combination of elements stays clean.
In my opinion when will mankind learn how to build better oil tankers so there won't be any more oil spills into the Earth's Finest Waters and every creature on earth can enjoy the pure taste of what suppose to be the pure taste of water ?
