from an unexpected source, fish poop. The increase in carbon
dioxide in the atmosphere not only drives global warming,
but also raises the amount of CO2 dissolved in ocean water,
tending to make it more acid, potentially a threat to sea life.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.oregonlive.com/newsflash/index.ssf?/base/national-9/1232046630218190.xml&storylist=technology"><P>Alkaline chemicals like calcium carbonate can help balance
this acid. Scientists had thought the main source for this
balancing chemical was the shells of marine plankton, but
they were puzzled by the higher-than-expected amounts of
carbonate in the top levels of the water.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.oregonlive.com/newsflash/index.ssf?/base/national-9/1232046630218190.xml&storylist=technology"><P>Now researchers led by Rod W. Wilson of the University of
Exeter in England report in the journal Science that marine
fish contribute between 3 percent and 15 percent of total carbonate.</P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/31FCDA12-2857-4307-BFCD-5283165A22B5/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
