The existence of deserts is a mere engineering problem. We could eliminate<br>them all if we made a modicum of effort, using technology that already<br>exists. I don't know why humankind has not done much to turn the Sahara
<br>into a forest, or farmland, or something useful. Such a waste of otherwise<br>good real estate, oy.</blockquote><div><br>You don't see it in the U.S. but some are doing just that. I believe it is Dubai which has the largest indoor skiiing facilities in the world. The program I believe pointed out that Libya is building a massive pipeline to move underground water from far inland to the coasts where the people are (presumably for the purposes you mention -- farmland, etc.) The concern is that due to the lack of rainfall it is using an unsustainable resource (like our oil pipelines). The program also suggested that the decline in rainfall over the Sahara was due to a cooling of the Earth -- so if we get global warming we may get a wet N. Africa as well. A wetter N. Africa, more farmable/livable land in Canada and Sibera, a navigable
N.W. passage, free carbon available to anyone for building nanostuff ... Jeepers -- it sure seems like people are getting all bent out of shape about something which on balance would have lots of good consequences. Lets put all the polar bears in climate controlled zoo habitats and find a nice arctic island (soon to be non "arctic") where we can send all the nonprogressites so they can live with their own "kind" :-|.
