In The Netherlands they are testing the growth of potatoes on salt water.

So we can also try to adapt to salt water

That's because the salt water penetrates deep into the land due to the topography of the Netherlands.

There Dutch have practiced salt water farming and management for a long time. That said you can't drink salt water ;)

Strictly speaking you can drink salt water. But it wouldn't hydrate you since you would still be thirsty.
