Recently, 36 countries attended a UN International Seabed Authority meeting in Jamaica to discuss whether mining companies should be permitted to extract metals from the ocean floor.<\/li>\n<\/ul>\n<h2>Deep Sea Mining<\/h2>\n<ul>\n<li>Deep sea mining involves extracting mineral deposits and metals from the ocean\u2019s seabed.\u00a0<\/li>\n<li>It is classified into three types:\n<ul>\n<li>Collecting polymetallic nodules from the ocean floor<\/li>\n<li>Mining massive seafloor sulphide deposits<\/li>\n<li>Stripping cobalt crusts from underwater rocks<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h3>Significance of Deep Sea Mining\u00a0<\/h3>\n<ul>\n<li>These deposits contain valuable materials like nickel, rare earth elements, and cobalt, which are essential for renewable energy technologies, batteries, and everyday electronics such as cellphones and computers.<\/li>\n<\/ul>\n<h3>Technological Developments in Deep Sea Mining<\/h3>\n<ul>\n<li>The engineering methods for deep sea mining are still evolving. Companies are exploring:\n<ul>\n<li><strong>Vacuum-based extraction<\/strong> using massive pumps<\/li>\n<li><strong>AI-driven deep-sea robots<\/strong> to selectively pick up nodules<\/li>\n<li><strong>Advanced underwater machines<\/strong> to mine materials from underwater mountains and volcanoes<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h3>Strategic Importance<\/h3>\n<ul>\n<li>Governments and companies see deep sea mining as crucial due to depleting onshore reserves and rising global demand for these critical materials.<\/li>\n<\/ul>\n<h2>Key Findings of the Study<\/h2>\n<ul>\n<li>The study examined the long-term impact of a small-scale mining experiment conducted in 1979 on a section of the Pacific Ocean seafloor.\u00a0<\/li>\n<li>The experiment involved removing polymetallic nodules, and scientists analyzed the affected 8-meter strip during an expedition in 2023.<\/li>\n<\/ul>\n<h3>Key Findings<\/h3>\n<ul>\n<li><strong>Long-Term Environmental Impact<\/strong>: The mining led to lasting changes in the sediment and a decline in marine organism populations.<\/li>\n<li><strong>Partial Recovery Observed<\/strong>: While some areas showed little to no recovery, certain animal groups were beginning to recolonize and repopulate.<\/li>\n<\/ul>\n<h3>Broader Concerns About Deep Sea Mining<\/h3>\n<ul>\n<li>Previous studies have warned about negative effects of deep sea mining below 200 meters, including:\n<ul>\n<li>Harmful noise and vibrations<\/li>\n<li>Sediment plumes and light pollution<\/li>\n<\/ul>\n<\/li>\n<li>A 2023 study in <i>Current Biology<\/i> found that deep sea mining significantly reduces animal populations and has a wider ecological impact than previously estimated.<\/li>\n<\/ul>\n<h3>Significance for Policy and Environmental Debate<\/h3>\n<ul>\n<li>The study provides crucial data for assessing the long-term effects of deep-sea mining and guiding future regulations by the <a

while some marine life begins to recover, full ecosystem restoration remains uncertain and may take decades.<\/li>\n<li>The research forms part of the Seabed Mining and Resilience to Experimental Impact (SMARTEX) project, which aims to support informed decision-making on deep-sea mining&#8217;s societal and ecological implications.<\/li>\n<\/ul>\n<h2>Deep-Sea Mining and Its Future<\/h2>\n<ul>\n<li>The <a href=\"https:\/\/vajiramandravi.com\/current-affairs\/clarion-clipperton-zone\/\" target=\"_blank\">Clarion Clipperton Zone (CCZ)<\/a> is a vast, mineral-rich region in the Pacific Ocean, home to unique deep-sea biodiversity and crucial metal resources.<\/li>\n<li>CCZ is a vast plain in the North Pacific Ocean between Hawaii and Mexico.<\/li>\n<li>It is known to hold large volumes of polymetallic nodules containing minerals used in electric vehicles and solar panels including manganese, nickel, copper, and cobalt.<\/li>\n<li>Governments and companies are increasingly considering deep-sea mining to meet global demand for critical minerals needed in renewable energy and technology.<\/li>\n<li>The ISA is currently evaluating whether and under what conditions deep-sea mining should be permitted.<\/li>\n<\/ul>\n<h2>Deep-Sea Mining Impact FAQs<\/h2>\n<p><strong>Q1.<\/strong> What is deep-sea mining?<\/p>\n<p><strong>Ans.<\/strong> Extracting minerals like cobalt, nickel, and rare earth elements from the ocean floor.<\/p>\n<p><strong>Q2.<\/strong> What are the key findings of the study?<\/p>\n<p><strong>Ans.<\/strong> Mining leaves lasting sediment changes and reduces marine biodiversity, with recovery taking decades.<\/p>\n<p><strong>Q3.<\/strong> Why is deep-sea mining controversial?<\/p>\n<p><strong>Ans.<\/strong> It threatens fragile ecosystems, disrupts biodiversity, and raises environmental concerns.<\/p>\n<p><strong>Q4.<\/strong> How does deep-sea mining affect marine life?<\/p>\n<p><strong>Ans.<\/strong> It disturbs habitats, creates harmful sediment plumes, and causes long-term biodiversity loss.<\/p>\n<p><strong>Q5.<\/strong> What is the International Seabed Authority\u2019s role?<\/p>\n<p><strong>Ans.<\/strong> The ISA regulates deep-sea mining activities and debates future environmental safeguards..<\/p>\n<p><strong>Source: <\/strong><a
