A team of researchers from a US Research Institute is about to head to the infamous Great Pacific Garbage Patch to spend a month analysing the impact of the garbage on the ecosystem.

It’s a set of circular currents in the North Pacific into which plastic rubbish that’s entered the sea from countries across the Pacific has gathered in high concentration.
The man credited with bringing the patch to the world’s attention is Captain Charles Moore of the Algalita Marine Research Institute.
He says it’s grown substantially since he first noticed it in the late 1990s.
