Henderson-uninhabited island of trash
May 22, 2017

This island is located about halfway between New Zealand and Chile and is recognised as a UNESCO world heritage site.

It is one of the few atolls in the world whose ecology has been practically untouched by a human presence. Its isolated location provides the ideal context for studying the dynamics of insular evolution and natural selection. It is particularly notable for the 10 plants and four land birds that are endemic to the island

Why in news:

Every day on Henderson Island - one of the most remote places on Earth - trash from every continent except Antarctica washes up its shores. Fishing nets and floats, water bottles, and plastics break into small particles against the rocks and sand.



Sources of these debris:

  • The plastics from the global seas that are swept into the South Pacific Gyre (a circular ocean current that functions like a conveyor belt, collecting plastic trash) are depositing it onto tiny Henderson’s shore at a rate of about 3,500 pieces a day.
  • Much of the trash consists of fishing nets and floats, water bottles, helmets, and large, rectangular pieces. 
  • Nearly 18 tons of plastic had piled up on the island giving Henderson the highest density of plastic debris recorded anywhere in the world.
