Hamwe nabantu bake, umuntu yatekereza ko Arctique yahinduka akarere katarangwamo plastike, ariko ubushakashatsi bushya bwerekana ko butari kure yukuri.Abashakashatsi biga inyanja ya Arctique basanga imyanda ya plastike ahantu hose.Nk’uko Tatiana Schlossberg wo mu kinyamakuru The New York Times abitangaza ngo amazi ya Arctique asa nk'ahantu hajugunywa plastike ireremba hamwe n'amazi yo mu nyanja.
Plastike yavumbuwe mu 2013 n'itsinda mpuzamahanga ry'abashakashatsi mu rugendo rw'amezi atanu bazenguruka isi mu bwato bw'ubushakashatsi Tara.Mu nzira, bafashe urugero rw’amazi yo mu nyanja kugira ngo bakurikirane umwanda wa plastiki.Nubwo ubusanzwe ubushakashatsi bwa plastike bwari buke, bwari mu gace kamwe ko muri Greenland no mu majyaruguru yinyanja ya Barents aho ubushakashatsi bwari hejuru cyane.Bashyize ahagaragara ibyo babonye mu kinyamakuru Science Advances.
Plastike isa nkaho igenda igenda yerekeza kuri gere ya termohaline, umuyoboro wa “convoyeur” wo mu nyanja utwara amazi ava mu nyanja ya Atalantika yo hepfo yerekeza ku nkingi.Mu kiganiro n'abanyamakuru, Andrés Cozar Cabañas, umushakashatsi muri kaminuza ya Cadiz muri Espagne, yagize ati: "Greenland n'Inyanja ya Barents byapfuye muri uyu muyoboro wa polar."
Abashakashatsi bavuga ko igiteranyo cya plastiki muri ako karere ari toni amagana, kigizwe n'ibihumbi magana y'ibice bito kuri kilometero kare.Abashakashatsi bavuze ko igipimo gishobora kuba kinini kurushaho, kubera ko plastiki ishobora kuba yarirundanyije ku nyanja.
Eric van Sebille, umwe mu banditsi b'ubwo bushakashatsi, yabwiye Rachel van Sebille muri The Verge ati: “Nubwo igice kinini cya Arctique kimeze neza, hari Bullseye, hano hari ahantu hashyushye n'amazi yanduye cyane.”
Nubwo bidashoboka ko plastike izajugunywa mu nyanja ya Barents (amazi y’amazi akonje cyane hagati ya Scandinaviya n’Uburusiya), imiterere ya plastiki yabonetse yerekana ko imaze igihe runaka mu nyanja.
Ati: “Ibice bya pulasitike bishobora kubanza kuba bifite santimetero cyangwa ibirenge mu bunini bicika iyo bihuye n'izuba, hanyuma bigacikamo uduce duto kandi duto, amaherezo bigakora iki gice cya milimetero gifite plastike, ibyo twita microplastique.”- Carlos Duarte, yavuze ko umwanditsi umwe mu bushakashatsi Chris Mooney wo muri Washington Post.Ati: “Iyi nzira itwara kuva mu myaka myinshi kugeza ku myaka mirongo.Ubwoko bw'ibikoresho tubona bwerekana ko bwinjiye mu nyanja mu myaka mirongo ishize. ”
Nk’uko Schlossberg abitangaza ngo buri mwaka toni miliyoni 8 za plastiki zinjira mu nyanja, kandi uyu munsi toni zigera kuri miliyoni 110 za plastiki zirundanya mu mazi y'isi.Mu gihe imyanda ya pulasitike mu mazi ya Arctique iri munsi y’ijana ku ijana, Duarte yabwiye Muni ko gukusanya imyanda ya pulasitike muri Arctique byatangiye gusa.Imyaka myinshi ya plastike ituruka muburasirazuba bwa Amerika nu Burayi iracyari munzira kandi amaherezo izarangirira muri Arctique.
Abashakashatsi bagaragaje injyana nyinshi zo mu nyanja zo mu nyanja aho microplastique ikunda kwegeranya.Igiteye impungenge ubu nuko Arctique izinjira kururu rutonde.Mu kiganiro n'abanyamakuru, Maria-Luise Pedrotti yagize ati: "Aka gace ni impfabusa, imigezi yo mu nyanja isiga imyanda hejuru".Ati: “Turashobora kuba twiboneye ishingwa ry'ikindi cyondo ku isi tutumva neza ingaruka ziterwa n'ibimera ndetse n'ibinyabuzima.”
Nubwo ubu hari bimwe mu bitekerezo byo mu kirere byoza imyanda yo mu nyanja muri plastiki kuri ubu birimo gushakishwa, cyane cyane umushinga wo gusukura inyanja, abashakashatsi bashoje mu itangazo rigenewe abanyamakuru ko igisubizo cyiza ari ugukora cyane kugira ngo hatabaho kugaragara kwa plastiki mbere.Mu nyanja.
