What Happens to Plastic in the Ocean?

Dont you know about the continent of plastic. There is data about it that from the 90 and they done nothing And now it is worst. In the pacific, in one of this current, there is an accumulated amount of plastic that have combined and is now approximately the size of the country of France. You cant see it because it is underneat the surface of water at +/- 1m. And the worst is that the UN and many country governement knew about it since a long time but they did not say it, hide it and did not put any money to find a solution. It was an independant media and science group that revealed it to the world. Can someone tell me if they heard of it by any media in their country..
