  • Fish digestions help keep the oceans healthy

    LONDON, Jan. 15, 2009 (Reuters) — The digestive systems of fish play a vital role in maintaining the health of the oceans and moderating climate change, researchers said on Thursday.

    Computer models showed how bony fish produced a large portion of the inorganic carbon that helps maintain the oceans' acidity balance and was vital for marine life, they said.

    The world's bony fish population, estimated at between 812 million and 2 billion tons, helped to limit the consequences of climate change through its effect on the carbon cycle, University of British Columbia researchers reported in the journal Science.

    "This study is really the first glimpse of the huge impact fish have on our carbon cycle -- and why we need them in the ocean," researcher Villy Christensen and colleagues wrote.

    Calcium carbonate is a white, chalky material that helps control the acidity balance of sea water and is essential to the health of marine ecosystems and coral reefs.

    It helps regulate how much carbon dioxide oceans would be able to absorb from the atmosphere in the future, the researchers said.

    Until now, scientists believed calcium carbonate came from microscopic marine plankton. The new findings suggested between 3 percent and 15 percent of the material comes from bony fish, said Rod Wilson of the University of Exeter in Britain, who worked on the study.

    Bony fish, which include about 90 percent of marine species but not sharks or rays, produce calcium carbonate that forms crystals in the gut and is then excreted in chalky solids.

    "Because of the impact of global climate change, fish are likely to have an even bigger influence on the chemistry of our oceans in the future," Wilson said in a statement.

  • Since we easily have a trillion dollars in our budget to allocate for bailouts...

    Obama and Congress should mandate a bailout of our globe - take about oh... a billion bucks (that GM

    is going to spend IN BRAZIL - how does that create jobs here?) or so...

    and simply send two or three bags of calcium carbonate to all property tax payers in the US,

    and have them spread it out on their lawns.

    Well, maybe another billion floating around to the farmers for their fields, but that would be optional, depending

    on what crops they would grow.

    The calcium carbonate would absorb the CO2 and we'd save the world.

    Would someone with an "in" to Obama send this to him right away? Failing to do it quickly may result in

    the earth spontaneously combusting.

    No need for fame or fortune, well, maybe a little fortune, enough to put in a big farm pond for fishing and raising the

    fish for global warming considerations.

    It's enough that my creative genius can do good for mankind.

    I wish I had invented the "Calvin and Hobbes" comic strip. It's so... me.

  • Interesting, but a few days ago you did advocate bailout $$$ for farmers, including fish farms.

  • I did. I succumbed to greed and self-interest in a time of need.

    GO FARMERS !!! @@

    (at least I didn't ask for $$$$$$$$$$$$$$$$$$$

    for an ice-breaking cruiser ship or a redecorated Smithsonian, or Pro Football

    HOF which is down a road a little piece)

    Hmmm. Great article ! (We heard first, already, here !)
