In many parts of the world, the need of fresh water for the local population is much higher than the amount available. This is due to many reasons, including pollution, acidification, salination, and naturally low precipitation rates, but the problem remains that places are running out of fresh water that is needed for drinking and crop growing. This in turn has led to numerous plans of different plausibility to surface around the world. Many of these are expensive, some are reasonable, and many are outlandish. But one coming out of South Africa is truly exceptional in its ingenuity.
Right now, Cape Town, South Africa is in the middle of a multi year drought. This has led to its population of 4 million people to be restricted to 18.5 gallons per day per person. Does that not sound like a lot? Well, in comparison, the average American uses 80-100 gallons of fresh water each and every day. Which means the residents of this city on the southern tip of Africa use around 20% of the water many of us use daily. So, to try to combat this deficiency, one idea that has been proposed is to drag an iceberg from Antarctica to be slowly siphoned off for a fresh water supply. This plan would cost over $200 million per iceberg, so it is unlikely to ever occur, but the thought of a bunch of boats dragging a bunch of ice bergs to be used for water is certainly an interesting one!
