Izinto ezibolayo ezibolayo zinomthelela omncane emvelweni, zihlangabezana nentuthuko esimeme, zingaxazulula ngempumelelo inkinga yezemvelo nezinye izinkinga, ngakho-ke isidingo siyakhula, imikhiqizo yokupakisha ebolayo isetshenziswa kabanzi kuyo yonke imikhakha yokuphila.Ngenxa yokuthi izinto eziningi ezisetshenziswa emaphaketheni zingokwemvelo futhi zingonakaliswa ngaphandle kokwengeza i-catalyst, lezi zixazululo zisetshenziswa kakhulu embonini yokudla neziphuzo.Izimboni eziningi nohulumeni baye bathatha izinyathelo zokunciphisa ukulahlwa kwezinto ezibonakalayo kanye nomthelela emvelweni.Izinkampani ezifana ne-Unilever kanye ne-P & G zithembise ukuthuthela ezixazululweni zokupakisha zemvelo futhi zinciphise indawo yazo yemvelo (ikakhulukazi ukukhishwa kwekhabhoni) ngo-50%, okungenye yezinto eziqhuba ukusetshenziswa kwamaphakheji abolayo ezimbonini ezihlukahlukene.Imikhiqizo eminingi emisha, efana nezixazululo zokupakisha ezizenzakalelayo nezihlakaniphile embonini, ziyakhula kuze kube sekugcineni imikhiqizo.

Abantu abaningi abanomthwalo wemfanelo baqhubekela ezixazululweni ezisimeme zokupakisha.

Isibalo sabantu emhlabeni sesidlule ibhiliyoni eziyisi-7.2, kuthi abangaphezu kwezigidigidi ezi-2.5 baneminyaka eyi-15-35.Bafaka ukubaluleka okwengeziwe endaweni ezungezile.Ngokuhlanganiswa kwenqubekelaphambili yezobuchwepheshe kanye nokukhula kwenani labantu emhlabeni wonke, amapulasitiki namaphepha asetshenziswa kakhulu ezimbonini ezihlukahlukene.Izinto zokupakisha ezitholakala emithonjeni ehlukahlukene (ikakhulukazi amapulasitiki) zakha imfucuza ebalulekile ebalulekile, eyingozi kakhulu emvelweni.Amazwe amaningi (ikakhulukazi amazwe athuthukile) anemithetho eqinile yokunciphisa imfucuza futhi akhuthaze ukusetshenziswa kwezinto zokupakisha ezibolayo.
