Mappi.net : Maps of continents : The 7th Continent|
The 7th Continent term is the name given to the new continent of marine waste created by humans. The waste is made up to 89% plastic, an estimated 10% of plastic in the world end in the oceans. The islands of waste are very hard to locate by satellite because they consist of very small pieces of plastic mobile and predominantly deep. That's why it's a little known phenomenon to date.
