Hello StuRat I'm mickey 63 please excuse me if I get the etiquette wrong I'm new to this type of discussion. I asked a question yesterday(18 March)if it was possible to transform desert into arable farmland,I received various answers one of which was interesting because it goes along with my own train of thought.Firstly, to construct a man made hole in a suitable place and then tow an iceberg to that place to make a lake.You would of course need a canal system to get the iceberg to the hole and for distribution,but is it possible?
