Deep-sea mining study uncovers hundreds of new species—and big risks
Scientists spent five years exploring the ocean floor between Mexico and Hawaii, discovering nearly 800 different species, most of which were new to science, and over 4,000 marine creatures.
The project, a team-up between European researchers and The Metals Company, aimed to see how deep-sea mining affects life at depths of 4,000 meters.
Mining takes a real toll on ocean life
The study found that mining vehicles cut animal numbers by 37% and reduced species diversity by almost a third—mostly because they scrape away the top layer of sediment where most creatures live.
Some species coped better with the disruption, eventually returning after the sediment settled.
Why it matters for our future tech—and the planet
These findings show that grabbing minerals for green tech can seriously harm deep-sea ecosystems we barely understand.
Researchers are urging more studies and strict rules before commercial mining starts, so we don't risk losing these fragile habitats before we even get to know them.
