Continents of garbage adrift in oceans and nobody is working on it

As much as 10 per cent of plastics produced end up inside giant marine vortexes

The best-known patch, known by some as the Great Pacific Ocean Garbage Patch, consists of an estimated 100 million tonnes of plastic debris that has accumulated inside a circular vortex of currents known as the North Pacific gyre. Environmentalists call it the Pacific Trash Vortex.

It is estimated to be anywhere from 700,000 square kilometres -- an area larger than Alberta -- up to 15 million square kilometres (the size of two Australias), depending on how it is measured

An estimated 100,000 marine mammals die each year from eating or being entangled in debris -- mostly plastic -- in the North Pacific alone. Hence the vortex's other nickname: the Plastic Killing Fields.

Ocean currents and winds are slowly bringing debris -- estimated to be 10 per cent of the world's plastic production -- to the centre of five major ocean gyres in the North and South Atlantic, North and South Pacific and the Indian Oceans
