Fragments of rock with green incrustations have raised the alarm of geologists working on Trindade Island in Brazil.
The hybrids between natural rock and plastic, sometimes with fragments of fishing nets, have become a common finding in the protected area.
On the island, the human population is minimal.
The only inhabitants are the Brazilian Navy agents who protect the turtles that come to the beaches to lay their eggs in a key nesting area in the world.
Pollution reaches the beaches carried by ocean currents.
Experts, such as Fernanda Avelar, a geologist at the University of Paraná, are concerned about the human legacy coming to light on the island.
“Pollution, garbage in the sea, and plastic improperly discarded in the oceans is becoming geological material, preserved in the Earth’s geological archives,” says the researcher.
