Siphila kwiplanethi enhle, kodwa ngeshwa kuba nzima ukuthola izindawo zemvelo ezihlanzekile. Kulezi zinsuku, ipulasitiki ingenye yezinto ezisetshenziswa kakhulu, futhi futhi ingenye yalezo ezithatha isikhathi eside ukubola; empeleni, isikhwama sepulasitiki esilula kungathatha iminyaka eyi-150 ukwehlisa isithunzi. Futhi ... kubonakala sengathi okwamanje akukho okuzoshintsha.
Futhi kufanele: sidale amathani epulasitiki angaphezu kwamabhiliyoni ayi-8 kusukela ngo-1950 ngokusho kocwaningo oluholwa yi-UC Santa Barbara yisazi semvelo sezimboni uRoland Geyer. Ngabe siya epulasitiki?
Ukubone kahle okubonwayo, kungenzeka kakhulu. UGeyer nethimba lakhe bathole ukuthi ukukhiqizwa komhlaba kwama-resin kanye nama-fibers emhlabeni wonke kukhuphukile kusuka kumathani ayizigidi ezi-2 ngonyaka ka-1950 kuya ngaphezu kwamathani ayizigidi ezingama-400 ngonyaka ka-2015. Futhi ijubane lokukhiqizwa kwepulasitiki akubonakali kwehla: Enanini eliphelele lama-resin kanye nemicu yepulasitiki ekhiqizwe phakathi kuka-1950 no-2015, cishe uhhafu wakhiqizwa eminyakeni eyi-13 edlule.
Okubi kakhulu akukhona ukukhiqizwa uqobo, osekuvele kuyakhathaza, kepha iqiniso lokuthi kuthatha isikhathi esingaphezu kwekhulu ukwehlisa isithunzi, noma isikhathi eside. Mayelana nalokhu, umbhali osebenza naye ocwaningweni uJenna Jambeck, onguprofesa wezobunjiniyela eNyuvesi yaseGeorgia, uthe "amaplastikhi amaningi awenzi i-biodegrade nganoma iyiphi indlela ezwakalayo, ngakho udoti wepulasitiki owenziwe ngabantu ungaba nathi amakhulu noma ngisho izinkulungwane zeminyaka".
Ishonaphi yonke leyo plastiki? Ingxenye ebalulekile, ngokudabukisayo, iya endaweni yemvelo. Ngo-2015 kuphela, ama-79% womkhiqizo aphelela ezilwandle nasezindaweni zemvelo. Ukusinikeza umbono wokuthi inkinga ibucayi kangakanani, kudingeka sikwazi lokho kumathani wamathani ayizigidi ezingama-275 akhiqizwa ngo-2010, cishe izigidi eziyi-8 zangena olwandle.
Yize kungeyona eyokukhipha ipulasitiki ezimpilweni zethu, abacwaningi bakholelwa ukuthi kuyaphuthuma ukuthatha izinyathelo zokugwema ukuphela kokuphila emhlabeni wepulasitiki.
