    Is America and the rest of the world doing enough to prepare for the Future water shortage?. There are prolonged droughts in the American Southwest, and in East Africa.

    The situation is expected to get a whole lot worse for the forseable future.
    Clean drinking water is already becoming a valuble commodity, and is at a limited supply.

    What is the United States, and the United Nations planing to do to address this future
    water crisis.?

    The drought in the central Rockies seems to be ending.

    Tide goes out somewhere, tide comes in somewhere else.

    Relax, the watersheds are fine. Not to mention the tremendous aquifers deep in the ground.
    Mother nature can take care of herself.
    My biggest concern is industry and everyday living screwing things up. Make sure the EPA is staffed with some hard-nosed hard-asses and enforce those environmental regs.

    Desalination is an energy intensive process for obtaining water. Globally, the amount of fresh water is not going to radically increase in the foreseeable future. As human population climbs so does the demand for water. Not just to drink, but also sanitation, agriculture and industry require water.
    Some areas have more water than others, so that inequality may shape future demographics. Those nations which are water poor may find their standards of living declining precipitately, while those with ample water will continue standard human behavior and consume as they please.

    Welcome to the future, except for us in Australia it's very much the present. On the most arid inhabited continent on Earth we have major water problems. Water is the number one political issue where I am and closely allied to that is concern about the environment and about population sustainabiity.

    We're building desal plants but they have their drawbacks as has been pointed out. But in a way we're lucky because most of our population lives on the coast and there aren't too many large population centres in the regional areas and in the extremely arid/desert areas in the centre. So at least desal plants, despite their drawbacks, will be of some use. How is that going to work in Kansas Toto?

    Be nice to Canada, she has your future water stores.

    Oh and before someone comes along and tells me that the US will simply take it, making the usual jokes about how Canada can't defend herself because the US does it for her - forget it, that sort of suggestion will be treated with the contempt it deserves.

    Not a water shortage, it is a people surplus.

    The earth has nearly the same amount of water that is has had for the past billion years.

    Water doesn't go anywhere...it just moves around.

    Actually at this pooint it is not a people surplus but a people distribution issue.

    Where?

    Why would we need to take anything? We have the Great Lakes! 22% of the world's freshwater in one convenient location!
