You’d think that 11 kilometers (6.8 miles) below the surface of the ocean you’d find a place free of all traces that humans exist, but a really, really rich guy disproved that theory this week.

Victor Vescovo, a private equity investor and explorer who has summitted the highest mountains on all of earth’s continents, recently broke the world record for deepest dive in a submersible.

During that dive, Vescovo spotted a plastic bag on the floor of the Mariana Trench.

Something to think about the next time you decide not to go shopping with a reusable cloth bag.

Maybe setting up some kind of “global fund” to help developing countries pay the cost of improving their waste management systems, as some researchers have suggested, might help. Who knows?

Check out the video below of a dive Vescovo made earlier this year to the Java Trench, where a new jellyfish species may have been discovered.
