Sir David Attenborough has urged countries to halt plans to mine the deep sea following the publication of a new report from Fauna & Flora International (FFI) that warns deep sea mining could cause significant loss of biodiversity, disruption of the ocean’s life-support systems and its carbon storage function.
Mining the deep sea could create a devastating series of impacts that threaten the processes that are critical to the health and function of our oceans.
Fauna & Flora International is calling on global governments to put in place a moratorium on all deep sea mining – a call I wholeheartedly support.
The report – The Risks and Impacts of Deep Seabed Mining to Marine Ecosystems – has been drafted by scientists at FFI and is the first to comprehensively assess the risks and potential impacts of mining the deep seabed for minerals. Its publication comes ahead of a July meeting of key countries hoping to finalise the rules that will govern deep sea mining. Minerals that can be found on the seabed are in increasingly high demand for use in technological appliances and equipment such as mobile phones and batteries.
The report presents a number of concerning findings about the potential impacts of mining the deep seabed including:
“Minerals on the seabed are centre-pieces of deep-sea ecosystems. Plans to mine the deep sea must be put on hold,” says Pippa Howard, Director at Fauna & Flora International. “The conclusions we have come to after extensive study could hardly be more troubling. From methane release to disruption of the ocean’s life-support systems and the destruction of unstudied ecosystems, the risks of deep sea mining are numerous and potentially disastrous.”

Human activity is already placing the ocean under severe strain. The ocean has absorbed one-third of all human carbon emissions and 93% of all the extra heat trapped by those emissions. The carbon dioxide dissolved in the ocean is making it more acidic, with consequences for marine ecosystems around the world, including coral reefs. In addition up to 13% of global fisheries have collapsed as a result of overexploitation and there are close to 500 ocean dead zones covering an area as large as the United Kingdom. By 2100 more than half of the world’s marine species may be close to extinction.
“The ocean is under immense stress from human activity and its function as a carbon sink keeps our planet habitable,” adds Pippa. “To place the ocean under the additional stresses that would be created by deep sea mining would be rolling the dice with the functioning of key planet-wide processes. We take this step at our peril. The evidence we have gathered suggests it’s time to pause deep sea mining plans and reconsider our use of the ocean before it’s too late.”
Exploratory deep sea mining is currently underway, but mining on a large scale is unable to commence until nations have agreed on the rules that will oversee the mining. These rules are under development via the governing authority, the United Nations International Seabed Authority (ISA), with influential parties and nations pushing for these rules to be finalised in 2020. The next meeting of the ISA is in Jamaica in July 2020. This report therefore comes at a critical time as world leaders decide on the future of the deep sea. Given the review of evidence presented in this report, FFI is calling for a moratorium on deep sea mining. A motion calling on nation states to support a moratorium will be debated at the IUCN World Conservation Congress to be held in Marseille, in June.
“[The idea] that we should be considering the destruction of these places and the multitude of species they support – before we have even understood them and the role they play in the health of our planet – is beyond reason,” Sir David says in the foreword to the report. “The rush to mine this pristine and unexplored environment risks creating terrible impacts that cannot be reversed. We need to be guided by science when faced with decisions of such great environmental consequence.”
