Blue Gold

What I learned from the movie Blue Gold  was that 3% is freshwater and  97% is salt water.The longest we can live without water is one week.When you see bubbles in the water it means it is loosing oxygen.We can't drink water that has salt on it!When it rains the water fells in the road and it can't be soaked by the dirt so it goes on into the ocean and the dirt dries.
