Desalination is a process that removes salt and minerals from seawater and turns it into a potable resource. It is extremely helpful in areas experiencing rising water demands due to water scarcity, droughts, growing populations and increased water consumption. With the ocean covering most of the Earth’s surface, seawater provides a sustainable, long-term solution to a problem that won’t soon dissipate.

By 2015, 18,000 desalination plants had cropped up worldwide, producing 22,870 million gallons of fresh water per day. Experts believe desalination, coupled with future advancements in technology, could be the key to establishing drought-proof communities worldwide.

A clean source of water is still a major concern in many places around the world. However, the process of desalination comes with its own environmental risks. Desalination’s role in the future of sustainability will depend on how these risks are addressed and adapted.
