Greenpeace have produced an online animation showing what they call the Trash Vortex.
Its all about how plastic rubbish either directly thrown or washed by rivers into the North Pacific, is swept up by the currents of a gigantic swirling vortex called the North Pacific Gyre. Have a look
According to the Greenpaeace article and as many of us already know the very thing that makes plastic items useful to consumers, their durability and stability, also makes them a problem in marine environments. Around 100 million tonnes of plastic are produced each year of which about 10 percent ends up in the sea. About 20 percent of this is from ships and platforms, the rest from land.
The North Pacific sub-tropical gyre covers a large area of the Pacific in which the water circulates clockwise in a slow spiral. Winds are light. 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 also been dubbed “the Asian Trash Trail” the “Trash Vortex” or the “Eastern Garbage Patch”.
