Argument: If natural iron fertilization occurs, it is OK for humans to do it
Jeremy Elton Jacquot. "Natural Iron Fertilization: Sahara Dust Storms Stimulate Huge Plankton Blooms". Tree Hugger. 10 Feb. 2008: Because of the controversy iron fertilization has managed to stir up over the past year (see Planktos' ill-fated efforts), many people probably still don't realize that it can be a natural process - and one that is likely to become more frequent due to climate change. The eastern Atlantic Ocean, for example, is often characterized by large phytoplankton blooms; the source of iron is the aeolian dust that blows off the coast of Africa from the Sahara desert.
