The Dangers of Deep Sea Mining Earthworks

For the mining industry, technological advances have made the world’s oceans the new frontier. Both companies and governments have started exploration and even tout deep-sea mining as a safer alternative to the problems caused by mineral extraction. But they do so in the absence of any scientific consensus on the long-term impacts of deep-sea mining.

SEABED MINING: RETENTION OF AN OVERALL PERSPECTIVE In the global debate about potential benefits and disadvantages of seabed mining for phosphates and other minerals, many arguments have been thrown to and fro. Companies wishing to pursue seabed mining are

Assessing the impacts of seabed mineral extraction in

2018-10-1  Mineral extraction from the seabed has experienced a recent surge of interest from both the mining industry and marine scientists. While improved methods of geological investigation have enabled the mapping of new seafloor mineral reserves, the ecological impacts of mining in both the deep sea and the shallow seabed are poorly known.
