It is so sad to see the growing water scarcity in the world.
Sadly with world problems like this many charity's come with short term solutions which feels like the idiom we use in my country, which is Mopping the floor while keeping the tap running.
But this also seems like a unique chance to me for humanity and south africa to improve their technology on converting salt water into fresh water.
I think terraforming and making new forests has also been shown as a potential to combat droughts because it keeps the water in the enviroment, like Antonio Vicente did in Brazil.
Sadly people feel like undertakings like these are too expensive.
In my opinion money should not be problem when it comes to saving the world.
I just read an article on planned desalination plants for Cape Town, so your take on it is really positive. Maybe there is hope, or forced hope.
