Actually, Hannah, the larger population in the eastern med is not Israelis. Perhaps, to take the more enlightened, environmentally green approach would be to to lower the population of the people where it would have the biggest impact. It's not a trivial problem. In the US, Australia, and other parts of the world where scarce water hasn't traditionally been a problem, the populations keep increasing geometrically. It'd be much better to have everyone limiit themselves to two babies a family. This is much better in thelong run for everyone. Not have people spread like a cancer over the face of the earth. Some I know in the really Radical Environemntal Left don't even think that nuclear bombs going off aren't a bad thing, overall. Short term radiation problems but reducing the population in an extreme kind of way. That's what you call a real extreme approach to things.
