Engxenyeni yesibili yekhulu lama-20, ngokuthuthuka kwesayensi nobuchwepheshe kanye nokuhlolwa okuqhubekayo kobuchwepheshe bokulondoloza izimbali, ubuchwepheshe bokukhiqiza izimbali ezingenakufa buye bathuthukiswa. Izindlela ezintsha zokucubungula nezinto ezisetshenziswayo zivumela izimbali ezilondoloziwe ukuthi zibukeke zingokoqobo futhi zihlale isikhathi eside.
Eminyakeni yamuva nje, izimbali ezilondoloziwe ziye zanda kakhulu ngenxa yokuphinda zisetshenziswe. Ngesikhathi esifanayo, ubuchwepheshe bokwenza izimbali ezingenakufa bubuye buthuthuke njalo ukuze buhlangabezane nesidingo semakethe sezimbali ezengeziwe zemvelo nemvelo. Izindlela zanamuhla zokwenza izimbali ezilondoloziwe zihlanganisa izindlela zokwelapha ezihlukahlukene zamakhemikhali nezinto zokwakha ukuze kuqinisekiswe ukuthi izimbali zigcina ukubonakala kwazo okukhanyayo isikhathi eside.
Isimo semakethe samanje sembali egciniwe
Imakethe yezimbali ezilondoloziwe njengamanje isesigabeni sokukhula ngokushesha futhi ithandwa abantu abaningi ngokwengeziwe. Lo mkhuba ubangelwa ikakhulukazi izici ezilandelayo:
1.Ukwanda kokuqwashisa ngokuvikelwa kwemvelo: Njengoba abantu benaka kakhulu ukuvikelwa kwemvelo kanye nentuthuko eqhubekayo, izimbali ezilondoloziwe ziya ngokuya zithandwa kakhulu njengembali esetshenziswa kabusha. Uma kuqhathaniswa nezimbali ezintsha, izimbali ezilondoloziwe zingagcina ukubukeka kwazo okukhanyayo isikhathi eside, ukunciphisa ukuthengwa okuvamile nokumosha izimbali.
I-2.Ihlala isikhathi eside futhi iyonga: Izimbali ezilondoloziwe zihlala isikhathi eside futhi zingagcinwa iminyaka eminingana noma ngisho nangaphezulu, ngakho zinezinzuzo ekubukeni nasekuhlobiseni isikhathi eside. Nakuba izindleko zokuqala zezimbali ezilondoloziwe ziphakeme, abathengi abaningi bazimisele ukukhokha inani eliphakeme kuzo ngokucabangela izinzuzo zabo zesikhathi eside.
3.Ukudala kanye nezidingo eziqondene nawe: Izimbali ezilondoloziwe zingenziwa zibe ukuhlelwa kwezimbali kobumo nezitayela ezihlukahlukene ngokucubungula nokuklama okuhlukahlukene, ukuhlangabezana nezidingo zabantu zokuhlobisa komuntu siqu nokudala. Lo mkhuba wokwenza kube ngokwakho ukhuthaze nokuthuthuka kwemakethe yezimbali elondoloziwe.
4.Isidingo semakethe yezipho nemihlobiso: Izimbali ezilondoloziwe zinezinhlobonhlobo zezicelo njengezipho nemihlobiso, futhi zithandwa ibhizinisi kanye nabathengi ngabanye. Isibonelo, isidingo sezimbali ezilondoloziwe siyaqhubeka sikhula emishadweni, emikhosini, emhlobiso wasekhaya nakweminye imikhakha.
Ngokuvamile, imakethe yezimbali elondoloziwe ibonisa ukuthambekela kokukhula okusheshayo okuqhutshwa yizinto ezifana nokunyuka kokuqwashisa ngemvelo, isidingo esikhulayo sokwenza kube ngokwakho, ukusebenza kahle kwesikhathi eside, kanye nomnotho. Ngokusungulwa okuqhubekayo kobuchwepheshe kanye nesidingo sabathengi sezimbali zekhwalithi ephezulu, imakethe yezimbali elondoloziwe kulindeleke ukuthi iqhubeke nokugcina umfutho omuhle wokuthuthuka.
