Siphila kwiplanethi entle, kodwa ngelishwa kuya kusiba nzima ukufumana indawo ezicocekileyo zendalo. Kule mihla, iplastikhi yenye yezona zinto zisetyenziswa kakhulu, ikwayenye yezo zithatha ixesha elide ukubola; Ngapha koko, ingxowa yeplastiki elula inokuthatha iminyaka eyi-150 ukwehla. Kwaye ... kubonakala ngathi okwangoku akukho nto izakutshintsha.
Kwaye kufanele: Senze ngaphezu kwe-8 yezigidigidi zeetoni zeplastiki ukusukela ngo-1950 ngokophando olukhokelwe ngu-UC Santa Barbara ngugqirha wezinto eziphilayo uRoland Geyer. Ngaba siya eplastikini?
Ukubona kakuhle okubonwayo, kunokwenzeka ngakumbi. UGeyer kunye neqela lakhe bafumanise ukuba imveliso yeplastikhi yeplastiki kunye neentsinga ezandayo inyuke ukusuka kwizigidi ezibini zeetoni ngonyaka ngo-2 ukuya kuthi ga ngaphezulu kwezigidi ezingama-1950 zeetoni ngonyaka ka-400. Kwintlaka iyonke kunye neentsinga zeplastiki eziveliswe phakathi kowe-1950 nowama-2015, malunga nesiqingatha saveliswa kule minyaka ili-13 idlulileyo.
Eyona nto imbi ayisiyiyo imveliso ngokwayo, esele ikhathaza, kodwa yinto yokuba kuthatha ngaphezulu kwenkulungwane ukuthoba isidima, okanye nangaphezulu. Ngokuphathelene noku, umbhali owayesebenza kunye naye uJenna Jambeck, unjingalwazi onxulumene nobunjineli kwiYunivesithi yaseGeorgia, wathi "uninzi lweeplastikhi alubiyiyo yonke into, ngenxa yoko Inkunkuma eyenziwe ngabantu inokuba kunye nathi kangangamakhulu okanye amawaka eminyaka».
Iya phi yonke le plastiki? Inxalenye ebalulekileyo, ngelishwa, iya kwindalo esingqongileyo. Ngo-2015 kuphela, i-79% yemveliso iphele elwandle nakwimeko yendalo. Ukusinika umbono wokuba inkulu kangakanani ingxaki, kufuneka siyazi loo nto yezigidi ezingama-275 zeetoni eziveliswe ngo-2010, malunga nezigidi ezisi-8 zangena elwandle.
Ngelixa ingekuko ukususa iplastikhi kubomi bethu, abaphandi bakholelwa ekubeni kungxamisekile ukuthatha amanyathelo okuthintela ukuphela kokuphela kwihlabathi leplastiki.
