What is deep sea mining? And what should the world do about it? Welcome to a brand new miniseries exploring the facts and evidence around deep sea mining, and covering the growing case for a moratorium on the practice.  

The ocean’s seabed harbours a range of mineral reserves containing valuable metals and compounds. But under international law these resources have been designated “the common heritage of mankind”, a designation backed up by the body responsible for both preserving and allowing their use, the International Seabed Authority. Today, for the first time, this body is being seriously tested: some companies are saying they are ready to mine the deep sea, and are demanding to do so. 

In this first of three episodes we discuss the ecological and environmental impacts of deep sea mining, explain its legal status, cover recent developments at the International Seabed Authority, and start to separate rhetoric from reality.
