Ngabantu abambalwa kakhulu, umntu unokucinga ukuba iArctic iya kuba yindawo engenaplastiki, kodwa uphononongo olutsha lubonisa ukuba ayikho kude kakhulu enyanisweni.Abaphandi abafunda uLwandlekazi lweArctic bafumana inkunkuma yeplastiki kuyo yonke indawo.Ngokutsho kukaTatiana Schlossberg weThe New York Times, amanzi aseArctic abonakala njengendawo yokulahla iplastiki edadayo nemisinga yolwandle.
Iplastiki yafunyanwa kwi-2013 liqela lamazwe ngamazwe labaphandi ngexesha lohambo lweenyanga ezintlanu emhlabeni jikelele kwinqanawa yophando iTara.Endleleni, bathatha iisampulu zamanzi olwandle ukujonga ungcoliseko lweplastiki.Nangona ugxininiso lweeplastiki lwaluphantsi ngokubanzi, lwalubekwe kwindawo ethile eGreenland nakumantla oLwandle iBarents apho ugxininiso lwaluphezulu ngokungaqhelekanga.Bapapashe oko bakufumanisileyo kwiphephancwadi iSayensi Advances.
Iplastiki ibonakala ngathi ihamba ecaleni kwe-thermohaline gyre, umsinga wolwandle “webhanti lokuhambisa” elithwala amanzi ukusuka kumazantsi oLwandlekazi lweAtlantiki ukuya ezipalini."IGreenland kunye noLwandle lwaseBarents lufile kulo mbhobho we-polar," umbhali wesifundo esikhokelayo u-Andrés Cozar Cabañas, umphandi kwiYunivesithi yaseCadiz eSpain, uthe kwi-press release.
Abaphandi baqikelela ukuba inani elipheleleyo leplastiki kummandla ngamakhulu eetoni, eziquka amakhulu amawaka amaqhekeza amancinci ngekhilomitha nganye yesikwere.Isikali sinokuba sikhulu ngakumbi, abaphandi bathi, njengoko iplastiki inokuthi iqokelele kumgangatho wolwandle kwindawo.
U-Eric van Sebille, umbhali oncedisana nolu phando, uxelele uRachel van Sebille kwi-Verge: “Nangona uninzi lweArctic lulungile, kukho iBullseye, kukho le ndawo ishushu enamanzi angcoliseke kakhulu.”
Nangona kungenakwenzeka ukuba le plastiki ilahlwe ngokuthe ngqo kuLwandle iBarents (ummandla wamanzi abandayo ngumkhenkce phakathi kweScandinavia neRashiya), imeko yeplastiki efunyenweyo ibonisa ukuba sele ikwixesha elithile elwandle.
“Amaqhekeza eplastiki asenokuba nee-intshi okanye iinyawo ngobukhulu aye arhabaxa xa evezwe lilanga, aze ke aqhekeke abe ngamasuntswana amancinane namancinane, ekugqibeleni enze le plastiki inomlinganiselo wemilimitha, esiyibiza ngokuba yi-microplastic.”- UCarlos Duarte, uthe u-co-author wokufunda uChris Mooney weWashington Post.“Le nkqubo ithatha ukusuka kwiminyaka emininzi ukuya kumashumi eminyaka.Ke uhlobo lwezinto esizibonayo zibonisa ukuba zangena elwandle kumashumi eminyaka eyadlulayo. ”
Ngokutsho kweSchlossberg, i-8 yezigidi zeetoni zeplastiki zingena elwandle minyaka yonke, kwaye namhlanje malunga ne-110 yezigidi zeetoni zeplastiki ziqokelela emanzini ehlabathi.Ngelixa inkunkuma yeplastiki kumanzi ase-Arctic ingaphantsi kwepesenti enye yazo iyonke, uDuarte uxelele uMuni ukuba ukuqokelelwa kwenkunkuma yeplastiki kwiArctic kusanda kuqala.Amashumi eminyaka eplastiki evela empuma ye-US naseYurophu isendleleni kwaye ekugqibeleni iya kuphelela kwi-Arctic.
Abaphandi bachonge ii-gyres ezininzi ze-subtropical kulwandle lwehlabathi apho ii-microplastics zidla ngokuqokelelana.Yintoni ngoku ixhalabileyo kukuba iArctic iya kujoyina olu luhlu."Le ndawo sisiphelo, imisinga yolwandle ishiya inkunkuma phezu komhlaba," utshilo umbhali-mbhali uMaria-Luise Pedrotti kwingxelo yeendaba."Sisenokuba sibona ukusekwa kwenye indawo yokulahla inkunkuma eMhlabeni ngaphandle kokuqonda ngokupheleleyo umngcipheko kwizityalo nezilwanyana zalapha."
Nangona ezinye iingcamango ze-pie-in-the-sky zokucoca i-debris yolwandle kwi-plastiki ngoku ziphononongwa, ngokukodwa iprojekthi ye-Ocean Cleanup, abaphandi baqukumbela kwi-press release ukuba isisombululo esona sisombululo kukusebenza nzima ukukhusela ukubonakala kweplastiki. Ekuqaleni.Elwandle.
