How deep-sea mining could threaten a vital ocean food source

Here is a 191-word summary of the key points from the news article: The article discusses how deep-sea mining for battery minerals could threaten a vital ocean food source. New research published in Nature Communications suggests that the waste from mining operations could starve tiny zooplankton and other creatures in the ocean's "twilight zone", between 200-1,500 meters deep. This could have cascading effects on the entire ocean food web, potentially impacting larger fish like tuna that many people depend on. The Trump administration has tried to circumvent international law to allow companies like The Metals Company to start commercial deep-sea mining, despite calls from over 900 scientists for a freeze. The waste from mining operations could replace the zooplankton's nutritious food source with less nutritious sediment particles. This "junk food" would starve the zooplankton and the creatures that rely on them, with far-reaching consequences. The article notes that advances in battery technology and e-waste recycling could limit the need for deep-sea mining, and argues that we "don't need to dig up the deep sea to power the green revolution."
