FAQs about Water Pollution and Shortage
4. Why is not the water in the seas desalinated?
Seawater desalination plants have been around for a long time, but the process was very expensive and until recently they were only used in extreme conditions. Today, more than 24 million cubic meters of desalinated water are produced per day in the world, enough to supply more than 100 million people.
The desalination process is a half-hearted solution since on the one hand it can solve the problem of drinking water shortage, but on the other it can cause damage to the flora and fauna. When salt is extracted, saline residues and pollutants that are unfavorable to the environment are generated. In addition, the system requires a very high electricity consumption. This could be solved by the use of clean energy such as wind, solar or tidal energy, perhaps the most appropriate.5. What are the main water pollutants?
