This week’s On The Radio segment discusses how an extremely remote island in the Pacific ocean bares the highest litter density in the world.
Transcript: Henderson Island is one of the most remote islands in the world and is also the most affected by pollution from plastic debris.
This is the Iowa Environmental Focus.
When researchers traveled to the tiny, uninhabited island in the middle of the Pacific Ocean, they were astonished to find an estimated 38 million pieces of trash washed up on the island.
The island is situated at the edge of the South Pacific gyre, where ocean currents meet in a vortex that captures floating trash, carrying some of it from as far away as Scotland.
Over 99 percent of the debris on the island is made of plastic—most pieces are unidentifiable fragments. The researchers say that fishing-related activities and land-based refuse likely produced most of the debris.
The researchers say the density of trash was the highest recorded anywhere in the world, despite Henderson Island’s extreme remoteness. The island is located about halfway between New Zealand and Chile and is recognized as a UNESCO world heritage site.
