Instead of reducing CO2 to minimize global warming what about finding a way to "use" it.
I am not a biologist but use more practicality so bear with me. I used an idea from some TED videos about finding solutions to current global problems using solutions already found in nature. I began searching for large amounts of CO2 emissions found naturally on earth and came up with this.
Carbon dioxide is also introduced into the oceans through hydrothermal vents. The Champagne hydrothermal vent, found at the Northwest Eifuku volcano at Marianas Trench Marine National Monument, produces almost pure liquid carbon dioxide, one of only two known sites in the world.
As I studied this more carefully I found this photo http://www.bing.com/images/search?q=The+Champagne+hydrothermal+vent&qpvt=The+Champagne+hydrothermal+vent&FORM=IGRE#view=detail&id=B4E22BACC231B4C4DE9E3D24CA7AA1B6740F24D9&selectedIndex=11.
It shows mussels and shrimp that thrive near these vents. So then I did research on them and found... In the late 1970s, scientists who study the deep seas made a surprising discovery of vents of hot water rising from the sea floor into the cold waters of the Pacific Ocean, according to marine biologist, Dr. Tony Rice. Since the 1970s a number of vents have been located in all of the world's main oceans, usually at depths between 2,000 and 3,000 meters (6,560 and 9,840 feet). What was also surprising is that animal communities thrive around these vents. This is the home for the giant vent mussel.
My idea is there may be a solution to our problem found already naturally around these vents? If not maybe another solution can be found naturally around some other major CO2 emission in nature?
