There's a new rock on Earth — or at least at Hawaii's Kamilo Beach.

Called plastiglomerate, the rock forms when plastic melts and gets mixed with lava rock, coral and sand, researchers report in the June Geological Society of America Today. The team notes that because plastic is everywhere and does not degrade naturally, plastiglomerate may permanently preserve humans' trashy ways in the planet's future rock record.
