Plastistone is the umbrella term for rocks that have fused with plastic. At the end of 2023 there were numerous sightings of green-colored plastic seemingly melted to rocks.[1] It forms from plastic that floats through the ocean and melts to the rocks over time.[2] So far, the stone has appeared on 5 continents.[3][4] It was recently spotted in March 2023 on the Brazilian remote island of Trindade by geologist Fernanda Avelar Santos[5][6] and has been seen in Hawaii a decade before.[7]
