深海采矿规则博弈：全球海洋治理的十字路口
Some three miles beneath the Pacific’s surface, the abyssal plain is a monochrome blur of sediment and sporadic life that has barely stirred for millennia—until now. Strewn across this lightless terrain are potato-sized polymetallic nodules, accreted over millions of years and rich in nickel, cobalt, and manganese, metals deemed essential for the green-energy transition. The prospect of harvesting them has ignited a paradigm shift in extractive ambition, moving humanity from the continents to a realm that legally belongs to no single state. But as the nascent industry accelerates, its advocates and detractors are locked in a debate that probes the very essence of planetary stewardship: can we exploit a biome we barely comprehend without repeating the devastations of terrestrial mining, or should the deep ocean remain a sanctuary, its resources indefinitely untouchable?
The commercial logic is seductive. Demand for battery metals is projected to soar, and land-based reserves are often concentrated in geopolitically volatile regions or require energy-intensive processing. Companies such as The Metals Company, a Canadian-registered outfit, argue that nodule extraction could yield a veritable battery in a stone, potentially lowering the carbon footprint of electric vehicles if done at scale. Norway’s government made headlines in 2023 by opening a vast area of its continental shelf to exploration, and China, Japan, and South Korea have invested heavily in exploratory licences. With autonomous underwater vehicles and riser systems that can vacuum nodules from the seabed, the technology is no longer science fiction; a handful of test extractions have already taken place. The race, proponents contend, is not one of reckless greed but of strategic necessity, a way to secure the metals required to electrify transport networks worldwide.
