为什么在对稀有金属的广泛影响知之甚少的情况下，公司和政府却决心开始商业规模的稀有金属开采？

一个多星期以来，世界各国的代表一直在牙买加Kingston参加国际海底管理局（ISA）的会议。国际海底管理局是 30 年前根据《联合国海洋法公约》成立的，其任务是保护国际水域的海床--约占世界海洋面积的一半。最近一次会议的目标是制定钴、锰和镍等金属的商业开采规则。这些金属的需求量越来越大，主要用于为电池储存等低碳技术提供动力。

会议将于3月29日结束，研究人员越来越担心最终文本的制定过于仓促。一些采矿业人士希望明年就开始挖掘工作。

Why are companies and governments determined to start commercial-scale mining for rare metals, when so little is known about its wider impacts?

For more than a week, representatives of nations around the world have been meeting at a session of the International Seabed Authority (ISA) in Kingston, Jamaica. The ISA was established under the UN Convention on the Law of the Sea 30 years ago with the task of protecting the sea bed in international waters — which comprise roughly half of the world’s ocean. The goal of the latest meeting is to write the rules for the commercial mining of metals such as cobalt, manganese and nickel. These are needed in increasing quantities, mainly to power low-carbon technologies, such as battery storage.

The meeting is set to end on 29 March, and there’s mounting concern among researchers that the final text is being rushed. Some in the mining industry would like excavations to begin next year.
