Mining the ocean floor: 5 deep-sea sources of critical minerals essential to technology, and the fragile marine life at risk

The ocean floor contains five identified sources of critical minerals essential for modern technology and renewable energy, according to marine geologists. These minerals, including lithium, cobalt, and rare earths, are found in polymetallic nodules, seafloor massive sulfides, and other formations, offering an alternative to vulnerable land-based supply chains. However, these deep-sea deposits are often located in sensitive marine environments, raising concerns about potential damage to fragile and largely unexplored ecosystems. The pursuit of these resources highlights a growing tension between technological demand and environmental preservation in deep-sea exploration.
