Every single piece of synthetic plastic that has ever been manufactured since 1950 is still in existence today, as each one takes thousands of years to break down. A recent study has indicated that plastic litter can become fused with rocks and other materials to form a new material: plastiglomerate. This material could very well become a permanent part of the geological record, forever marking humanity’s impact on the world.
