A small island smack in the middle of the South Pacific has never been inhabited by people — and yet, its white sand beaches are home to more than 37 million pieces of junk.

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.

In 2015, Jennifer Lavers, a researcher at the University of Tasmania, traveled to Henderson in an effort to document the extent of plastics pollution. Her research paper has since gone viral.

Lavers shared images from her trip with us.
