Concepts de base
Deep sea mining for metals to produce renewable energy technologies and batteries poses significant risks to fragile deep-sea ecosystems, potentially disrupting critical oxygen production and releasing vast amounts of stored carbon.
Résumé
The article discusses the recent scientific discovery of "dark oxygen" production by metallic nodules found on the ocean floor, which challenges the narrative that deep sea mining is a sustainable solution for renewable energy and battery production.
The author provides an overview of what these metallic nodules are and how they are formed over millions of years, serving as important habitats for deep-sea life. However, the proposed mining techniques to extract these nodules would involve heavily disturbing the seafloor, stirring up sediment and organic matter that has accumulated over millennia.
This could have devastating consequences for deep-sea ecosystems, potentially disrupting the production of "dark oxygen" that supports complex life in the absence of photosynthesis. Furthermore, the release of the stored carbon in the seafloor sediment could contribute to climate change, undermining the very purpose of using the mined metals for renewable energy technologies.
The article also highlights the conflict of interest within the International Seabed Authority (ISA), which is tasked with protecting the "common heritage of mankind" but is also funded by corporations with vested interests in deep sea mining. The author argues that once a profitable extraction method is found, the ISA will likely justify the destruction of deep-sea ecosystems in the pursuit of short-term profits.
The article concludes by questioning the sustainability and wisdom of the technocratic approach that views the Earth's resources as mere "commodities" to be exploited, rather than recognizing their intrinsic value and role in supporting life. It suggests that indigenous wisdom, which sees the Earth as a living, interconnected system, may offer a more holistic and sustainable perspective.

"Removing them would be akin to yanking a couple of wires out of the back of your computer just because you don't know what they're for."
"Sediment, building up for multiple millennia and serving as a graveyard for billions of tons of dead algae (and who knows what other organisms), would be ploughed and stirred up heavily by the nodule collector."
"What these billions of tons of half-decomposed organic waste would do to marine life is anyone's guess."
