CTA and ETC Group oppose dumping of iron nanoparticles in ocean to “control” global warming
June 19, 2007

In a June 19, 2007 Letter of Concern, ICTA and ETC Group demand EPA fully investigate the legality of Planktos, Inc.’s past and future “iron seeding” activities under the U.S. Ocean Dumping Act. The San Francisco-based company intends to transport and dump 100 tons of iron nanoparticles off the coast of the Galapagos Islands without permit in Summer 2007. According to the company’s website, they undertook a similar illegal dumping operation in 2002. Possible environmental impacts of this untested geo-engineering project include increased production of nitrous oxide and methane, possible toxic plankton blooms, and unforeseen impacts on ocean ecosystems
