Earth has a special calendar called the geologic time scale…We are currently in the Holocene Epoch, but some scientists believe we have entered a new time called the Anthropocene or the “Age of Humans” because of our impact on the planet. One of the biggest changes humans have made is inventing and using plastic..Because plastic is now found everywhere, some scientists, like us, think we have entered a new stage in Earth’s history called the Plasticene…

Plastic-rock hybrids found on the Andaman Islands – Mongabay

Rocks called "plastiglomerates" - because they are made of a mixture of sedimentary granules and other debris held together by plastic, mainly fishing nets - have been found in Brazil's volcanic Trindade Island. Researchers view this as evidence of humans' growing influence over the earth's geological cycles (screenshot taken from Global News video "Mutated "plastic rocks" discovered on remote Brazilian island," March 23, 2023, via Youtube).

A study found the formation of plastic-rock hybrids in the intertidal zone of remote beaches of Aves Island in the Andaman archipelago. This is a first record of these hybrid rocks, known as plastiglomerates, from India.
Samples from the island that were analysed contained polyethylene and polyvinyl chloride. Incineration of plastic litter could have led to their formation.
The impact of plastiglomerates on marine ecosystems is yet to be understood as research on plastiglomerates is an emerging field…
