Most of Earth water is saltwater , around 97 %
Water may be our one of greatest resources , but could it be our greatest enemy ?
Seiji O ’ Brien
When you walk into your house on a hot , summer day and you get a glass of water from your kitchen sink , do you think about what ’ s in it ? Where did this water come from , how does it come out of the sink so clean ? Who makes this water clean and what happens to it ? It makes you wonder what our live would be like without clean fresh water . How would we live if all of the Earth ’ s water were irreversibly polluted ?
