Humans cannot drink saline water, but, saline water can be made into freshwater , for which there are many uses. The process is called “desalination”, and it is being used more and more around the world to provide people with needed freshwater.
How do you make seawater drinkable to survive?
Desalination is the process of removing salt from seawater, making it drinkable. This is done either by boiling the water and collecting the vapor (thermal) or by pushing it through special filters (membrane).

Why is desalination bad?
What are the environmental impacts of desalination? ... Desalination has the potential to increase fossil fuel dependence , increase greenhouse gas emissions, and exacerbate climate change if renewable energy sources are not used for freshwater production. Desalination surface water intakes are a huge threat to marine life.
What happens if you drink sea water?
Human kidneys can only make urine that is less salty than salt water. Therefore, to get rid of all the excess salt taken in by drinking seawater, you have to urinate more water than you drank . Eventually, you die of dehydration even as you become thirstier.
Why are oceans salty but not lakes?
Rain replenishes freshwater in rivers and streams , so they don't taste salty. However, the water in the ocean collects all of the salt and minerals from all of the rivers that flow into it. ... In other words, the ocean today probably has a balanced salt input and output (and so the ocean is no longer getting saltier).
