“Pollution Has Reached Geology,” Researcher Says About Plastic Rocks Found on Remote Brazilian Island

Brazilian researchers report the finding of “plastic rocks” on the remote island of Trindade, part of a volcanic archipelago about 1,100 kilometres off mainland Brazil. Chemical tests revealed the main pollutant forming these plastiglomerates to be synthetic fishing nets that wash ashore and ‘melt’ into the sediment when temperatures rise. “This is new and terrifying at the same time, because pollution has reached geology,” says Fernanda Avelar Santos, a geologist at the Federal University of Parana.
