Ngo-2050, kuya kubakho malunga ne-12 yeebhiliyoni zeetoni zenkunkuma yeplastiki emhlabeni

Abantu bavelise iitoni ezizibhiliyoni eziyi-8.3 zeplastiki.Ngo-2050, kuya kubakho malunga ne-12 yeebhiliyoni zeetoni zenkunkuma yeplastiki emhlabeni.

Ngokutsho kophononongo olukwiJournal Progress in Science, ukusukela ekuqaleni kweminyaka yoo-1950, iitoni ze-8.3 yeebhiliyoni zeeplastiki ziye zaveliswa ngabantu, uninzi lwazo ziye zaba yinkunkuma, engenakuhoywa ngenxa yokuba zibekwe kwindawo yokulahla inkunkuma okanye zisasazeke kwindalo. okusingqongileyo.

Iqela, elikhokelwa ngabaphandi beYunivesithi yaseGeorgia, iYunivesithi yaseCalifornia, iSanta Barbara kunye neMarine Education Association, yaqala ukuhlalutya imveliso, ukusetyenziswa kunye nesiphelo sayo yonke imveliso yeplastiki emhlabeni jikelele.Abaphandi baqokelele idatha yezibalo malunga nokuveliswa kwee-resin zamashishini ahlukeneyo, iifibers kunye nezongezo, kwaye zidibanise idatha ngokohlobo kunye nokusetyenziswa kweemveliso.

Izigidi zeetoni zeplastiki zingena elwandle minyaka le, zingcolisa iilwandle, zingcolise iilwandle kwaye zibeke esichengeni izilwanyana zasendle.Amasuntswana eplastiki afunyenwe kwimihlaba, kwiatmosfera nakwiindawo ezikude kakhulu zoMhlaba, njengeAntarctica.IiMicroplastic zikwatyiwa ziintlanzi nezinye izidalwa zaselwandle, apho zingena khona kwikhonkco lokutya.

Idatha ibonisa ukuba imveliso yeplastiki yehlabathi yayiyi-2 yezigidi zeetoni kwi-1950 kwaye yanda ukuya kwi-400 yezigidi zeetoni kwi-2015, edlula nayiphi na into eyenziwe ngumntu ngaphandle kwesamente nentsimbi.

Kuphela yi-9% yenkunkuma yeemveliso zeplastiki eziphinda zisetyenziswe, enye i-12% iyatshiswa, kwaye i-79% eseleyo ingcwatywe nzulu kwiindawo zokulahla inkunkuma okanye iqokelelwe kwindawo yendalo.Isantya sokuveliswa kweplastiki asibonisi zimpawu zokucotha.Ngokweendlela zangoku, kuya kuba malunga ne-12 yeebhiliyoni zeetoni zenkunkuma yeplastiki emhlabeni ngo-2050.

Iqela lifumene ukuba akukho sisombululo se-bullet yesilivere ekunciphiseni ukungcoliswa kweplastiki yehlabathi. Endaweni yoko, utshintsho luyafuneka kulo lonke ikhonkco lokubonelela, bathi, ukusuka ekuveliseni iiplastiki, ukuya kwi-pre-consumption (eyaziwa ngokuba yi-upstream) kwaye emva kokusetyenziswa (ukuhlaziywa kwakhona). kunye nokusebenzisa kwakhona) ukunqanda ukwanda kongcoliseko lweplastiki kokusingqongileyo.
