On the island, located nearly 1,140 kilometres (708 miles) from the state of Espirito Santo within the southeast, melted plastic has interwoven itself with rocks, which geologists say is proof of people’ rising affect over the earth’s geological cycles.
“This is new and terrifying at the same time, because pollution has reached geology,” mentioned Fernanda Avelar Santos, a geologist on the Federal University of Parana, who spoke to Reuters.
Santos and her group carried out chemical exams to find out the kind of plastics found within the “plastiglomerates,” that are rocks composed of a mix of sedimentary granules and different particles held collectively by plastic.
“We identified [the pollution] mainly comes from fishing nets, which is very common debris on Trinidade Island’s beaches,” Santos mentioned. “The [nets] are dragged by the marine currents and accumulate on the beach. When the temperature rises, this plastic melts and becomes embedded with the beach’s natural material.”
The inexperienced turtle, Chelonia mydas, is without doubt one of the most endangered species on the earth, and yearly, 1000’s of them come to put their eggs on Trindade Island. The Brazilian navy, which retains a base on the island and guards the turtle nests, is the one human inhabitants on Trindade.
“The place where we found these samples [of plastic] is a permanently preserved area in Brazil, near the place green turtles lay their eggs,” Santos mentioned.
“We talk so much about the Anthropocene, and this is it,” Santos advised Reuters, referring to a proposed geological epoch outlined by people’ impression on the planet’s geology and ecosystems.
“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,” she added.
