Don’t rely on plankton to save the planet
Encouraging plankton growth in the ocean has been touted by some as a promising way to remove carbon dioxide from the atmosphere. ___1___.
Adding iron to patched of ocean can make plankton bloom temporarily. The microscopic organisms suck up dissolved carbon dioxide from the water, which in turn is replaced by carbon dioxide from the air. ___2___.
Jorge Sarmiento from Princeton and his colleagues developed a complex computer model to analyze how factors such as ocean chemistry and water circulation would affect the process if 160,000 square kilometers of ocean were seeded with iron for a month. ___3__.
In their scenario, which covers an area 10 times as big as the largest experiment of this kind ever proposed, fertilizing the ocean removes 1 million tons of carbon from the atmosphere-- just 0.2 percent of the carbon dioxide humankind spews out each month.
Rough estimates in the past have predicted similarly disappointing results. __4__ Says Sallie Chisholm, an environmental engineer from the Massachusetts Institute of Technology. "But the take-home message is the same. ___5___."
