I wonder if we could somehow use strategic placement of fertilisation to encourage processes that laterally help in cleaning up (/collecting) plastic pollution in oceanic gyres? A girl can dream. - ed: I am fascinated by the idea that otherwise horrid floating plastic pollution can act as centres for bio-accumlation leading to local, floating bio-domains. I guess the real problem is plastic bags and fishing nets, not toothbrushes that happen to float.
