The development in ocean mining and processing technology have led to a new boom in deep-sea mining as land mineral resources are being exhausted and the demand for metals has risen. As of 2022, the International Seabed Authority has signed 31 contracts to explore deep-sea mineral deposits.
Deep-sea mining has again triggered controversies. On one hand, proponents argue that deep-sea mineral deposits can replace fossil fuels such as coal and save the planet. Opponents, on the other hand, argue that deep-sea mining will damage
deepsea ecosystems and their biodiversity. The author will expound the causes and effects of deep-sea mining.
