    Post Solving the world's water shortages via desalination.

    I cannot imagine a bigger blunder in the history of ecology, than California's failed method of addressing their own "water shortage."



    Here is how to do it via reverse osmosis:

    Favoring gravel and penalties for watering your yard over 'grass lawns' are a recipe for INCREASING global warming (that's GLOBAL COOLING for you republicans).

    This is how we will fix it. Wait and millions of people will die.

    We do have a looming fresh water deficiency crisis in the US -- especially in the West.

    It's like we're afraid to address it, though. Yet another case of "let's cut funding to save money."

    Pretend that the problem doesn't really exist, and maybe it will just go away.

    The "faith based" solution to every problem.

    I can't wait to hear the half-ass'd explanations of why this should not go forward.....

    El Magtaa desalination plant was until recently the world's largest reverse osmosis desalination plant producing 500K cubic meters of drinking water / day. It is built and operated by Singapore's Hyflux.

    The Plant is located in western Algeria near Arzew (Mers El Hadjadj)

    I can see why you might think that, after all, grass is a plant, and plants convert CO2 into oxygen. But the truth is a bit more complicated:

    Maintaining grass produces carbon (or CO2). Running the mower, watering the lawn, and even the fertilizer we apply all produce CO2. The mower burns gasoline and converts it directly to CO2. In order for you to have water, the municipality must pump it around, and filter it this all requires energy and the production of energy produces CO2. Fertilizer needs to be mined, then processes and then delivered to your door. There are lots of engines burning fuel to make this happen.

    Lawns Reduce CO2 Levels - Garden Myths
    In ornamental lawns, nitrous oxide emissions from fertilization offset just 10 percent to 30 percent of the carbon that was sequestered. But day-to-day management required fossil fuel consumption that released as much or more carbon dioxide than the plots could take up.

    Does the same hold true for trees and shrubs?

    I don't know, but I imagine that when you factor in care and maintenance, even gravel is better at keeping CO2 out of the atmosphere than ornamental lawns.

    Do people mow, fertilize, and water their trees and shrubs like with grass? I kind of doubt it. I think mostly it's just the maintenance of keeping a lawn that undoes any co2 benefit. Instead, people should grow some kind of no-mow drought tolerant groundcover and quit being so obsessive about the lawn looking like the 8th hole at Pebble Beach.

    Also, it would probably be a lot more cost effective to work on pipeline systems to bring water down from the Pacific Northwest and Canada (where they have an unused surplus of fresh water which runs into the sea every year.)

    But desalinization wouldn't hurt either.
    Thanks from Coyote
