This is happening on an island in the South Atlantic, so obviously America doesn't need to worry about the problem.
Trindade Island is one of the world's most important conservation spots for green turtles, or Chelonia mydas, with thousands arriving each year to lay eggs on the beaches of the island. The Brazilian navy has a small installation with a research station on the island that provides protection for the turtles and several endangered marine bird species.
Scientists find rocks 'made of plastic' on remote island
Scientists say they are worried after finding rock made from plastic debris on a remote island in South America.
The discovery was made on Trindade Island, an uninhabited volcanic island off the east coast of Brazil. Experts say that melted plastic has become intertwined with the rocks and that pollution has mainly come from fishing nets. The island isn't inhabited by humans, however, the site is an important, protected area for green turtles.
Fernanda Avelar Santos, a geologist at Brazil's Federal University of Parana who was involved with the study said: "We identified (the pollution) mainly comes from fishing nets, which is very common debris on Trindade Island's beaches.
She explained: "The pollution, the garbage in the sea and the plastic dumped incorrectly in the oceans is becoming geological material ... preserved in the Earth's geological records."
