Enye yezinkinga zemvelo ezicindezela kakhulu inkinga yemifula. Isidingo sokonga imithombo yamanzi siyanda minyaka yonke. I-Russia ingumholi ngokwezindawo zamanzi ahlanzekile, kepha amanzi emifula engaphezu kuka-70% angcolile futhi awafanele nokusetshenziswa kwezobuchwepheshe. Esinye sezizathu ukungabi bikho kwezindawo zokuhlanza amanzi. Imishini esetshenziswayo iphelelwe yisikhathi, yingakho inqubo yokuhlanzwa kwamanzi ibuthaka ezweni lethu. Amanzi asezingeni eliphansi afaka inqwaba yezifo lapho abantu bevezwa khona, phakathi kwazo okuyingozi kakhulu isifo sokusha kwesibindi nezifo ezithathelwanayo.
Ngaphezu kokuba ngumthombo wokuphila kubantu, amanzi abalulekile ekugcineni impilo yazo zonke izinto eziphilayo emhlabeni. Umjikelezo wamanzi emvelweni uqinisekisa ukusatshalaliswa umswakama. Kwezolimo, amanzi emifula emincane asetshenziselwa izindlela zokunisela, kepha lokhu kuholela ekungcolisweni kwemithombo yamanzi ngemithi yokubulala izinambuzane, okwenza ukuthi ingakulungeli ukuphuza, kubantu nasezilwaneni.
Ukwelashwa
Ukuze amanzi ahlanzeke lapho engena ezinhlelweni zikamasipala zokuphakelwa kwamanzi emadolobheni nasemaphandleni, kudlula ezigabeni eziningana zokuhlanzwa nokuhlungwa. Kepha emazweni ahlukene, ngemuva kokwelashwa, amanzi awahlangani njalo nezindinganiso zenhlanzeko. Kunamazwe amaningi lapho ungathola ubuthi ngemuva kokuphuza amanzi ompompi. Ngaphezu kwalokho, amanzi angcolile asezindlini nasezimbonini awalashwa ngaso sonke isikhathi uma ekhishelwa emizimbeni yamanzi.
Ugesi nemifula
Enye inkinga yemifula ihlotshaniswa nomkhakha wamandla kagesi wezomnotho, lapho kusetshenziswa khona imifula emincane, umsebenzi wayo onikeza abantu ugesi. Zibalelwa ku-150 izikhungo zokuphehla ugesi ophehlwa ngamanzi ezweni. Ngenxa yalokhu, imibhede yemifula iyashintsha namanzi angcolisiwe, umsebenzi wamachibi agcwala ngokweqile, ngenxa yalokho lapho izimo zokuphila zayo yonke imvelo ziwohloka. Amakhulu emifula emincane ayanyamalala ebusweni bomhlaba minyaka yonke, okudala ukulimala okukhulu emvelweni, ukulahleka kwezitshalo nezilwane.
