深海采矿:绿色未来抑或生态浩劫?
Thousands of metres beneath the Pacific’s surface, in the Clarion-Clipperton Zone, lies an otherworldly plain carpeted with potato-sized polymetallic nodules—rock-like accretions rich in cobalt, nickel, and manganese. For decades, these deposits languished in obscurity, but a surge in demand for electric-vehicle batteries has propelled them to the centre of a ferocious global debate. Proponents argue that extracting these metals from the seabed could reduce reliance on terrestrial mines, many of which are entangled with child labour and deforestation. Yet the very idea of dispatching colossal machines to scrape an almost entirely uncharted ecosystem fills marine scientists with alarm, pitting the urgency of decarbonisation against the precautionary principle in a clash of incomparably high stakes.
The International Seabed Authority, a Jamaica-based body established under the UN Convention on the Law of the Sea, is the unlikely arbiter of this dispute. It has already issued dozens of exploration contracts to state-backed enterprises and private contractors, but it has yet to finalise a regulatory framework for commercial extraction—a process that has become a diplomatic minefield. Several Pacific island nations, whose economies are tethered to the ocean, have joined corporations in calling for swift approval, framing deep-sea mining as a sovereign right and a development opportunity. Conversely, a coalition of more than twenty countries, flanked by environmental NGOs and prominent scientists, is pushing for a moratorium, contending that the current scientific understanding is far too primitive to justify any exploitation.
