what are trash islands made of



  1. 0 Votes

    The Great Pacific Garbage Patch is composed primarily of plastic litter.  Various forms of plastics account for about 90% of the trash floating in the ocean.  Much of the plastic in the garbage patch has been broken down into tiny particles, so small that they can’t be seen by the naked eye.  These particles are considered uniquely problematic as their size enables them to easily enter and accumulate in marine food chains.
