![]() The traditional method of desalination involves boiling water and collecting the water vapor, which is free of the salt and minerals that are left behind. Today, over 18,000 desalination plants are in operation around the world. This water treatment method has been practiced since ancient times, when ship crews processed seawater for drinking water onboard. What is Desalination?ĭesalination is the process of turning saltwater into freshwater by removing its salt content. In order for humans to consume seawater, it must first be desalinated. More urine would be expelled from the body than water consumed, leading to dehydration and eventually, death. If humans drink seawater, the kidneys would be forced to eliminate the salt by creating excess amounts of urine. The concentration of salt in the ocean is too high for the human body to process. How can so many people lack access to water when the majority of the world is covered in water? This is because most of the world’s water supply is found in seas and oceans, which are comprised of saltwater. Millions of people around the world, however, are faced with a lack of access to clean drinking water due to climate change, urbanization, and a rapidly growing human population. Having safe and sufficient access to water improves overall health and encourages economic development. Water is one of the most critical components to life on earth.
