Ngo-2050, i-yeplastiki olwandle lingaphezu iintlanzi

Siyazi ukuba ngenxa kwamaqondo obushushu kunye notshintsho lwemozulu ezalandela emva koko ekwabhengezwa amanzi olwandle iba ezifudumeleyo kunye dirtier. Okukhona carbon dioxide methane siya kukhupha emoyeni, i mandundu imeko. Kodwa elindela ihlabathi amanzi yenye ingxaki - kweplastiki. ubomi Modern igcwele kule nto, ukusukela upakisha ukutya iimoto. Plastic ngokupheleleyo yonke, nkqu olwandle. Ngokutsho uphando entsha, ngo-2050 inani zehlabathi amanzi zeplastiki luya kugqithisela inani yeentlanzi.

usongo Entsha amanzi zehlabathi

Ngokutsho kwengxelo entsha esuka Ellen MacArthur Foundation, ngaphezulu kwama-95% yehlabathi yeplastiki elahlwayo, lo gama i-5% kuphela ithunyelwa ukuze iqwalaselwe. ilahleko yezoqoqosho ukusuka loo ukukhululwa omkhulu izinto ukuya ku $ 120 billion ngonyaka. Phantse yonke yeplastiki ezilahliweyo isetyenziswa kanye kuphela. Malunga nama-40 ekhulwini inkunkuma zeplastiki kuhlala phezu ilizwe, kuxhomekeka kumgangatho eziphathekayo, siwuhlambele umhlaba kangangamakhulu eminyaka. ngaphezulu kancinane nje sesithathu zonke iiplastiki eveliswa ngonyaka, kuvela olwandle. Ezo kwamagciwane yonke ngcaciso kulingana ngexabiso ukukhululwa ngokupheleleyo imixholo enkunkumeni olwandle.

Projections ukuba elizayo

Ukususela ngo-1964, imveliso iiplastiki banda izihlandlo-20. Namhlanje ve million 343 iitoni izinto rhoqo ngonyaka. Kulindeleke ukuba eli nani kule minyaka ingama-20 ezayo liza kuphinda kwaye ngo-2050 - ezine, yaye onke kuba amazwe asaphuhlayo bayawufuna zeplastiki ngakumbi nangakumbi. Rudi ukuba sele ulwandle, kunokubangela umonakalo noqhekeko-bume.

Iintlobo ngeentlobo iintaka, iintlanzi kunye nezilwanyana zaselwandle abulawe ngokuthatha iingxowa zeplastiki kunye amasuntswana zeplastiki ukutya. Ingxaki nje kuphela zeplastiki, kodwa izibaso eziyimfuneko ukuze kufezekiswe loo mbandela. Le 6% lombane oyile iyonke ngo-2050 isabelo sayo liya kwanda ukuya ku-20%.

Ukubiza

Le ngxelo kufuneka ukuba utshintshe ngokupheleleyo imveliso, ukusetyenziswa kwakhona nokurisayikilisha zeplastiki. Ukuza kuthi ga ngoku, ngaphantsi eninzi ukudala iitoni ngeplastiki entsha kunokuba lizisebenzise ubudala. Kunzima ukufumana izisombululo kule ngxaki yehlabathi. Nokwandiswa yemarike kumazwe asakhasayo siyakhula nemfuno iiplastiki. Omnye isisombululo isenokuba ukunciphisa ukusetyenziswa kwale manqaku zokubopha imveliso ikakhulu ukubola zeplastiki. Kuyimfuneko ukuba ufunde ukwenza indlela inani sikhulu sala iiplastiki, okanye sebenzisa ngokuphindaphindiweyo.
