The water we drink and use is running short in the world. We all have to learn how to stop wasting our limited water. One of the steps we should take is to find ways of reusing it. Experiments have already been done in this field.

All we would have to do to make use of the seawater on earth is to get rid of the salt. This process is called desalination, and it is already in use in many parts of the world.
