Algalita's been at it (spreading news of the gyre) for TEN years! After pounding away at getting our attention to this plastics/ocean problemo, this year has been the most encouraging yet. Theirs is the 4th official expedition to the gyre this summer - read about it here (lotsa fun links & interactive maps!).
Capt Moore's campaign had a sloooow, loooonely start. Nobody wanted to believe it. Many of us couldn't believe it. But it made so much sense - and the oceans finally showed that they are finite in their capacity to deal with the human/plastic full-frontal assault. You could actually hear the cartoon light bulb turning on above your head.
The word is getting out beyond our green-centric circle - and people are responding to the problem...The Environment's the name, and Awareness is the GAME.
