Ngo-2050, kuzoba namathani ayizigidi eziyizinkulungwane eziyi-12 emhlabeni jikelele

Abantu bakhiqize amathani epulasitiki angu-8.3 billion.Ngo-2050, kuzoba namathani ayizigidi eziyizinkulungwane eziyi-12 emhlabeni jikelele.

Ngokocwaningo lweJournal Progress in Science, kusukela ekuqaleni kwawo-1950, amathani ayizigidi eziyizinkulungwane ezingu-8.3 epulasitiki akhiqizwa abantu, iningi lawo seliphenduke imfucumfucu, elingeke lishaywe indiva ngoba lifakwa ezindaweni zokulahla noma zihlakazeke endaweni yemvelo. imvelo.

Ithimba, eliholwa abacwaningi abavela eNyuvesi yaseGeorgia, iNyuvesi yaseCalifornia, iSanta Barbara kanye neMarine Education Association, laqale lahlaziya ukukhiqizwa, ukusetshenziswa kanye nesiphetho sokugcina sayo yonke imikhiqizo yepulasitiki emhlabeni wonke.Abacwaningi baqoqa idatha yezibalo ekukhiqizeni ama-resin ahlukahlukene ezimboni, imicu kanye nezithasiselo, futhi bahlanganisa idatha ngokuya ngohlobo nokusetshenziswa kwemikhiqizo.

Izigidi zamathani epulasitiki zingena olwandle minyaka yonke, zingcolise ulwandle, zingcolise amabhishi futhi zibeke nezilwane zasendle engozini.Izinhlayiya zePlastiki ziye zatholakala emhlabathini, emkhathini ngisho nasezifundeni ezikude kakhulu zoMhlaba, njenge-Antarctica.Ama-Microplastic abuye adliwe yizinhlanzi nezinye izilwane zasolwandle, lapho engena khona ochungechungeni lokudla.

Idatha ikhombisa ukuthi ukukhiqizwa kwepulasitiki emhlabeni wonke kwaba amathani ayizigidi ezi-2 ngo-1950 futhi kwanda kwafinyelela kumathani ayizigidi ezingama-400 ngo-2015, okudlula noma iyiphi impahla eyenziwe umuntu ngaphandle kukasimende nensimbi.

U-9% kuphela wemikhiqizo yepulasitiki eyimfucumfucu igaywa kabusha, enye i-12% iyashiswa, kanti u-79% osele ugqitshwe ekujuleni kwezindawo zokulahla imfucuza noma unqwabelana endaweni yemvelo.Ijubane lokukhiqizwa kwepulasitiki alibonisi izimpawu zokwehla.Ngokusho kwezitayela zamanje, kuzoba namathani ayizigidi eziyizinkulungwane eziyi-12 emhlabeni wonke ngo-2050.

Ithimba lithole ukuthi asikho isixazululo senhlamvu yesiliva yokunciphisa ukungcoliswa kwepulasitiki emhlabeni wonke. Kunalokho, kudingeka ushintsho kulo lonke uchungechunge lokuhlinzekwa kwempahla, bathe, kusukela ekukhiqizeni amapulasitiki, ukuya ekusetshenzisweni kwangaphambili (okwaziwa ngokuthi ngenhla nomfula) nangemuva kokusetshenziswa (ukuvuselela kabusha). nokusebenzisa kabusha) ukumisa ukusabalala kokungcoliswa kwepulasitiki endaweni ezungezile.
