Millions of people are running out of water – how desalination plants are trying to fix that

How desalination plants make ocean water drinkable

Today, one out of three people don't have access to safe drinking water. One reason is that 96.5% of that water is found in our oceans. It's saturated with salt, and undrinkable. Most of the freshwater is locked away in glaciers or deep underground. Less than 1% of it is available to us.

Desalination is an important tool in the fight against water scarcity. Its reliability is becoming critical. If you have a desalination plant, energy and seawater, you can reliably get clean water. But it's not a cure-all. There are concerns about the amount of energy required, how much it costs and its environmental impacts.

Water scarcity is a complex, difficult problem. Climate change is introducing growing uncertainty. Desalination uses a large amount of energy and, for some, it's fundamentally difficult advocating for a technology that would be adding to our growing, and mostly fossil fuel-based energy needs.

Watch the video to see how desalination provides safe drinking but creates other environmental concerns in the process.
