These resources encompass a vast array of living organisms and minerals found in oceans, seas, and other bodies of saltwater. The economic significance of marine resources cannot be overstated, as they contribute substantially to global fisheries, aquaculture, shipping, tourism, and pharmaceutical industries. The oceans act as a vast reservoir of biodiversity, offering a wealth of potential for scientific research and medical discoveries. However, the escalating issue of marine pollution poses a grave threat to these invaluable resources. Anthropogenic activities, ranging from industrial discharges to plastic waste, have resulted in severe environmental degradation, compromising the health of marine ecosystems and adversely impacting the economic potential of these resources. Understanding the intricate relationship between marine resources and the consequences of pollution is essential for developing sustainable practices that can ensure the long-term well-being of our oceans and the global economy.<\/p>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_73 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<label for=\"ez-toc-cssicon-toggle-item-6a00eefe1c6d9\" class=\"ez-toc-cssicon-toggle-label\"><p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-cssicon\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/label><input type=\"checkbox\"  id=\"ez-toc-cssicon-toggle-item-6a00eefe1c6d9\"  \/><nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/edukemy.com\/blog\/give-an-account-of-marine-resources-and-their-economic-significance-how-has-marine-pollution-affected-such-resources-upsc-geography-optional-mains-2023\/#Answer\" title=\"Answer\">Answer<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/edukemy.com\/blog\/give-an-account-of-marine-resources-and-their-economic-significance-how-has-marine-pollution-affected-such-resources-upsc-geography-optional-mains-2023\/#In_case_you_still_have_your_doubts_contact_us_on_9811333901\" title=\"In case you still have your doubts, contact us on 9811333901.&nbsp;\">In case you still have your doubts, contact us on 9811333901.&nbsp;<\/a><ul class='ez-toc-list-level-4' ><li class='ez-toc-heading-level-4'><ul class='ez-toc-list-level-4' ><li class='ez-toc-heading-level-4'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/edukemy.com\/blog\/give-an-account-of-marine-resources-and-their-economic-significance-how-has-marine-pollution-affected-such-resources-upsc-geography-optional-mains-2023\/#Visit_our_YouTube_Channel_%E2%80%93_here\" title=\"Visit our YouTube Channel &#8211;&nbsp;here\">Visit our YouTube Channel &#8211;&nbsp;here<\/a><\/li><\/ul><\/li><\/ul><\/li><\/ul><\/nav><\/div>\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Answer\"><\/span>Answer <span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The biotic and abiotic resources found in the oceanic water and bottoms are called marine resources.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"532\" height=\"484\" data-src=\"https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/01\/Screenshot-2024-01-12-114934.png\" alt=\"\" class=\"wp-image-21765 lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" style=\"--smush-placeholder-width: 532px;
