It’s also possible, these scientists warn, that deep-sea mining could disrupt the way carbon is stored in the ocean, contributing to the climate crisis. A documentary about deep-sea mining that Sweetman watched in a hotel bar in São Paulo, Brazil, unleashed a breakthrough. However, several countries, including the United Kingdom and France, have expressed caution, supporting a moratorium or ban on deep-sea mining to safeguard marine ecosystems and conserve biodiversity. Earlier this month, Hawaii banned deep-sea mining in its state waters. Many unanswered questions remain about how dark oxygen is produced and what role it plays in the deep-sea ecosystem.
