If this pyrococcus takes all the carbon dioxide out of the atmosphere, WHAT WILL ALL THE OTHER PLANTS BREATHE?  This is basic grade-school Biology;  animals inhale oxygen and exhale carbon dioxide, and plants inhale carbon dioxide and exhale oxygen.  If pyrococcus gets loose in the atmosphere, all the other plants will suffocate -- and then so will we.  Real smart move, U of G.
