Here is why it is prohibitive. Water is freedom. If people have clean water, they have an opportunity to create economies. Economies create wealth and innovation. Wealth and innovation create solutions to the worlds problems. Can’t have that in a utopian paradise.
Take all the money given to the UN each year and build desalination plants along the African coast and you eliminate global hunger and poverty. Unfortunately to the commies, that cannot happen. Building desalination plants removes any water from the ocean that would cause massive flooding as well as green large swaths of land which will eat CO2 and produce oxygen.
Yep. Desalinization will cause global warming before the the next week is out. . . or come up with some other excuse. Just one more reason for the UN to hate Israel.
