Desalination requires a ton of energy and money. As is with everything else on the planet, governments won't move until it hits the fan. We live in a world of over consumption of resources. I agree there is plenty of sea water in the world, and with the icecaps melting, it's a good idea to take as much of it as we can to make it into drinkable water to just maybe keep the oceans from rising. But from the stand point of 2022, we will run out of fresh water if nothing changes. They've known about this impending issue for almost a decade now and not much has been done about it. I wish it weren't so, but it is what it is.
