Deep-sea mining starves life in the ocean’s twilight zone https://www.sciencedaily.com/releases/2025/11/251108012850.htm
Scientists have discovered that deep-sea mining plumes can strip vital nutrition from the ocean’s twilight zone, replacing natural food with nutrient-poor sediment. The resulting “junk food” effect could starve life across entire marine ecosystems.
Deep-sea mining in the Clarion-Clipperton Zone may release waste into midwaters that support diverse marine life. This study finds such discharges could dilute key food particles and disrupt trophic links from zooplankton to large marine predators.

A new study led by researchers at the University of Hawai‘i (UH) at Mānoa published today in Nature Communications is the first of its kind to show that waste discharged from deep-sea mining operations in the Pacific’s biodiverse Clarion-Clipperton Zone (CCZ) could disrupt marine life in the midwater “twilight zone” — a vital region 200-1,500 meters below sea level that supports vast communities of zooplankton, tiny animals that serve as the ocean’s basic food building blocks. Specifically, it finds that 53% of all zooplankton and 60% of micronekton, which feed on zooplankton, would be impacted by the discharge, which could ultimately impact predators higher up on the food web.
Leaders from across the Pasifika nations unite to voice their opposition to #DeepSeaMining
We have no right or place to harm an ecosystem of which we know less about than we do the surface of Mars.
"Deep below the surface of the Pacific Ocean, the seafloor is dotted with clusters of brown and black rocks, each containing valuable metals."
I look forward to capitalism fucking up the last bit of the planet it hasn't fucked up yet.

#Sharks, #rays, #chimaeras further threatened by #deepSeaMining
The habitat of thirty species of sharks, rays, and chimaeras, also called ghost sharks, overlap with areas where proposed deep-sea mining may occur, according to new research. Nearly two-thirds of these species are already threatened with extinction due to human impacts, so deep-sea mining, which will disrupt the seafloor and discharge large plumes of sediment into the water above, has the potential to elevate their extinction risk.
