Gyre is the name given to any large system of rotating ocean currents (particularly those involved with large wind movements). The largest of the 5 main gyres is found in the Northern Pacific ocean.It occupies an area of approximately 20 million square kilometres.It is the largest ecosystem on the planet. “The currents tend to force any floating material into the low energy central area of the gyre. There are few islands on which the floating material can beach. So it stays there in the gyre, in astounding quantities estimated at six kilos of plastic for every kilo of naturally occurring plankton. The equivalent of an area the size of Texas swirling slowly around like a clock. This gyre has been called the "Trash Vortex" or the "Eastern Garbage Patch"http://www.greenpeace.org/international/en/campaigns/oceans/pollution/trash-vortex/Ø What’s smart about a ‘disposable’ range of plastic that lasts 300-500 years?Ø What price would you pay to preserve our ecosystem?Ø Which bit of the planet should we ‘save’?
