Within their bodies they harbor highly productive algae -- a form of marine plant life -- that can "fix" carbon, use the energy of the sun to conduct photosynthesis and produce sugars.
While raising the tax is politically unpopular, theoretically, raising the gas tax would fix crumbling highways, lower oil imports, and reduce carbon emissions.
Still, there is a reasonable fear here that an illusory hope of a scientific fix might undermine the sort of dogged and grubby policy solutions, such as carbon caps and carbon quotas, needed for taking the fight against climate change to its source.
