It’s a rumor that we hoped would never be confirmed: at least 1,700 miles of plastic trash is floating in what is commonly known as the Great Pacific Garbage Patch. Up until this point, scientists only had a vague idea of the scope of the trash they would find in the North Pacific Gyre, a vortex where four ocean currents meet. Isolated patches have been reported by sailors and fishermen, but now researchers, sailors, journalists, and government officials on a nearly four-week journey through the gyre say that plastic shards and netting abound in a space bigger than the state of Texas

The title of the project refers to Thor Heyerdal's Kontiki Expedition undertaken in 1947. In the same way that the Kontiki Expedition challenged existing assumptions about past civilisations, it is intended that The Plastiki Expedition will change attitudes towards the world's oceans, the whole idea of waste and the increasingly unacceptable reality of pollution.
The Pastiki Epedition
The Plastiki set sail on 20 March 2010 upon a three-month voyage of 11,000 nautical miles from San Francisco to Sydney via the Great Pacific Garbage Patch.[37] Rothschild has used Twitter to update followers on how the voyage is progressing.[37]
