BY JACKIE JAFFE AND CAMERON DECHURCH<\/strong><\/p>\n Jackie Jaffe and Cameron DeChurch, undergraduate students at Duke University, served as DukeEngage interns for the North Carolina Marine Debris Action Plan. <\/em><\/p>\n Take a second and picture the ocean.<\/p>\n You might imagine sweeping blue seas, an opalescent wave crashing into the beach, or even a school of exotic fish journeying under the sea. Maybe your mind takes you to your last vacation on the beach and the gentle roar of the ocean as it greets the bank. The ocean in your mind probably is clear, shimmering, perfect.<\/p>\n Unfortunately, this is not the reality of our oceans today. Pleasurable activities like fishing or eating a picnic lunch can have unintended consequences for marine ecosystems, animals, and even human beings. Whether it\u2019s a fishing line left behind or a plastic bag that accidentally flew away, our small actions can negatively impact the earth for thousands of years.<\/p>\n Marine debris has become one of the biggest environmental threats to the planet, with plastic comprising the bulk of this problem \u2014 and it\u2019s not just sea turtles that are hurt by floating debris disguised as delicious jellyfish. When the fish we eat have ingested microplastics, we ingest these harmful substances, too.<\/p>\n As DukeEngage interns partnering with North Carolina Marine Debris Action Plan<\/em> organizations, our research project involved a close examination of North Carolina cleanup and observation reports from NOAA\u2019s Marine Debris Tracker App and the Ocean Conservancy. When we looked at the numbers from 2016 to 2021, we learned that our state\u2019s marine debris included 552,957 collected or observed items.<\/p>\n In North Carolina, under the Coastal Area Management Act there are 20 counties along the coast subject to unique legislation to better protect the marine environment. From 2016 to 2021, the Marine Tracker App recorded 33,794 items in these counties. Plastic comprised over 70% of that waste.<\/p><\/div>\n Eleven of North Carolina\u2019s 20 coastal counties reported almost three-quarters of this trash; the other nine coastal counties did not submit clean-up reports. All told, the statewide total of over one-half million items came from only 59 reporting counties (out of N.C.\u2019s 100 counties), underrepresenting the amount of trash in the state\u2019s environment.<\/p>\n Diving deeper into the statistics shows that cigars and cigarette butts are the most prominent kinds of marine debris in North Carolina, nearly one-third of the total trash reported. This isn\u2019t a surprise; tobacco waste is the most commonly reported litter worldwide. Once in the environment, cigarette butts release chemicals, including arsenic, which are harmful to marine life.<\/p>\n After analyzing data on the composition of marine debris, we found plastic to be the most common substance, comprising 71% of the items collected. This includes water bottles, grocery bags, utensils, and anything else manufactured with that difficult-to-decompose material.<\/p>\n Plastic water bottles, for instance, can take 450 years to break down. Because they didn\u2019t exist before the 1940s, every plastic water bottle that consumers haven\u2019t properly recycled or disposed still exists in the environment today.<\/p>\n<\/a>
