The race to mine trillions of rocks from the ocean floor
In short: Deep beneath the Pacific, polymetallic nodules hold the metals needed for our modern world. This video explores the looming industrialization of one of Earth's least understood ecosystems and the lasting environmental scars left by deep-sea extraction.
Polymetallic nodules—rich in nickel, cobalt, copper, and manganese—take millions of years to form on the seafloor. While mining these resources could alleviate pressure on destructive land-based mines, it poses a significant risk to fragile marine life. The documentary examines the mechanics of deep-sea machinery and the legal complexities of who owns international seabed resources.
Evidence of long-term impact is already documented. A 1989 experiment showed that seafloor disturbances remained visible 26 years later, highlighting how slow these environments recover. This transition to industrial-scale mining threatens to disrupt ecosystems before scientists can fully map the species living within them.
