At the recent Libertarian Alliance conference in London, one of my favourite speakers, Leon Louw, mocked the idea that water on earth is scarce. Two-thirds of the Earth’s surface is covered with the wet stuff, in fact. What people mean when they say that water is scarce is not that there is a lack of H20, rather, there is a lack of drinkable, clean water. But the idea that water is scarce is, in and of itself, bonkers. As Leon said, if an alien from outer space talked to some ecological doomsters and heard their moans about water shortages, he would probably fly off in search of more intelligent life elsewhere.
Heaven knows what an intelligent alien would make of George Monbiot.
