Scientists predict that by 2016, the amount of fresh water produced by desalination plants will exceed 10 billion gallons (38 million cubic meters) a year, or double the rate in 2008.

I am sure that by the year 2025, scientists will have discovered an inexpensive, quick, and efficient means of desalinating salt water.
