Uma Amafeni Afaka Ubufakazi Bokuqhuma Afakwe Ezindaweni Zokugcina Izinto Eziyingozi

Ukufakwa kubalulekile ngokungangabazeki.

Yini ehlanganisa izinto eziyingozi ezivuthayo neziqhumayo? Lezi zihlanganisa izinto ezivutha kakhulu, eziqhumayo, eziguquguqukayo, futhi iyingozi kakhulu. Ezikhungweni zokugcina imfucuza eyingozi, akudingekile kuphela ukufaka izibani ezingaqhumi namaswishi kodwa namafeni angaqhumi, okuzenzakalelayo amanzi okufafaza amasistimu okucima umlilo, kanye nokugcina amakhemikhali ezitsheni zesibili (amaphalethi) ukunciphisa ukungcoliswa kwemvelo lapho kuvuza.
