Bush Administration plan to reduce global warming could devastate sea life
...Shallow-living organisms like shelled mollusks and corals
are already being affected by the growing levels of CO2 in the atmosphere. As atmospheric CO2 diffuses into the upper layers of the water, it inhibits the ability of shellfish to form shells and causes coral reefs to dissolve. Deep-sea creatures a...
