How Sperm Whales Offset Their Carbon Footprint 150
Boy Wunda writes "Scientists at Flinders University in South Australia found that in an awesome example of design by Mother Nature, Southern Ocean sperm whales offset their carbon footprint by simply defecating – an action that releases tons of iron a year and stimulates the growth of phytoplankton which absorb and trap carbon dioxide. If only we humans could say the same for our poop, which really doesn't do much more than just sit there." I'm going to do my part by buying some iron supplements and a can of chili, and heading off toward the ocean.

It had been proposed sometime ago that geoengineering might help fight global warming. One plan in particular that drew a lot of attention was the dumping of hundreds of tons of iron filings into the ocean. Through wave action, the seas absorb CO2 from the atmosphere and the theory went that iron dumping would encourage phytoplankton population growth which would, in combination with zooplankton, take in CO2 and deposit it on the bottom of the briny deep. ... ...
While it seems that impressive bio-blooms could be created, much of the zooplankton poop and other carbons bits didn't create the strong sedimentation effect expected on the briny bottom.
