I understand the need for people to have fresh water, I just don't understand the need to de-salinize water before pumping it into the Dead Sea..
If all they wish to do is raise the water level of the Dead Sea, then plain seawater should be fine..
If the concern is fresh water for human use, that is another matter, and the water level of the Dead Sea is a moot point..
Concerns over the Dead Sea seem to be the main thrust of the article however.
Those concerns can be addressed by simply piping seawater by the shortest route available..
