Scientists Discover Oxygen-Producing Rocks on Ocean Floor

New findings challenge long-held beliefs about oxygen production and raise concerns over deep-sea mining impacts.

Polymetallic nodules on the Pacific Ocean floor create oxygen through seawater electrolysis.
The discovery may alter our understanding of the origins of life and deep-sea ecosystems.
Mining companies dispute the findings, fearing impacts on their operations and environmental claims.
Researchers stress the need for further studies to confirm the oxygen production and its ecological significance.
The findings could influence future regulations and practices in deep-sea mining.
