Fresh water from the Antarctic.
Three-quarters of the world's fresh water is frozen. 90% of the ice is concentrated in the Antarctic. For tens of thousands of deposits formed ice mass reaches 240 quadrillion tons. These days every year this monstrous mass of ice grows during the winter period to 2400 billion tons, however, half the annual growth rate of ice disappears. Giant Antarctic ice is slowly slipping into the sea, and from them break off huge icebergs, which are then in a few years drifting and gradually melt away. Each summer the polar Antarctic sail 1,200 million tons of icebergs. They contain fresh water would be enough to ensure its 4-6 billion people. Antarctica - the world's largest repository of fresh water.
We cannot say that this finding is new and original. More than two decades ago, the American John Isaacs, suggested that transport the icebergs. Over the years, his idea did not find any response, until this strange proposal does not give impetus fantasy magazine publishers Life and they did not publish the material on this subject in one of his research - the popular series. Readers marveled at the project, but soon forgot about it. Several years later, two other Americans, Weeks and Campbell, have returned to this theme. They pointed out even that supposedly fairly distant past has already occurred towing icebergs to experience the coast of Peru. However, their performance has caused more curiosity than a serious interest in. Only a hard reality in recent years, the expected difficulties in securing water large areas of south-western United States, cause the immediate adoption of appropriate measures, prompted the U.S. administration to issue an order to conduct research on the icebergs.
Their result was the birth of solid scientific work about the possibilities of transport of the Antarctic ice. It has been prepared, "Rand Corporation." The authors have missed almost nothing in their studies. They have not forgotten any of the technology of transportation, nor the gradual melting of icebergs, or the choice of suitable deep-water routes, neither of the problems associated with the application of maritime law in polar coastal waters, nor, finally, to explore the possible impact on the environment.
