Covering over 70 percent of our planet, the ocean is still largely unexplored. Sailors and explorers have been traversing the seven seas for centuries, but we’ve barely scratched the surface. In fact, more people have been to the moon than have visited the ocean’s abyss, which is why a recent scientific paper from the journal PLOS ONE is so disconcerting.
In one of the largest scientific seafloor surveys to date, scientists used remotely-operated vehicles and trawl nets to examine 32 deep-sea sites in the Atlantic and Arctic oceans, as well as the Mediterranean Sea. The astonishing part—they found plastic bottles, fishing gear, and other man-made debris in all of them. Some of the debris items found had traveled more than 1,200 miles from the shore—most of it settling in remote, deep-sea caverns.
