Hmm, maybe use that water to make the deserts bloom?
Ezekiel 36:35
35 And they shall say, This land that was desolate is become like vthe garden of Eden; and the waste and desolate and ruined cities are become fenced, and are inhabited.
well, yeah, after the formation of Israel, the next big thing that precedes the end of the world is that the deserts are all be turned green.
What turns the deserts green is the collapse of desalination costs (which includes the collapse of energy costs). Desalination costs have been falling in half about once decade.
Right now there are couple developments in the works that may/likely/will speed the decline rate of desalination costs— including lftr thorium reactors which will collapse the cost of energy and graphene membranes.
