Desalinization is a water treatment process that removes salts from water. The difference between salt-water is that salt-water you can not drink and fresh-water you can drink. The reason you can not drink salt-water is because it takes the extra water out of your body and kills you.
Scientists are concerned about running out of fresh-water, so they are trying to figure out a way to change salt-water to fresh-water. “By 2020, desalinization will contribute significantly to ensuring a safe, sustainable, affordable, and adequate water supply for our nation.” God has a plan for everything.
