Ukonga amanzi - ukukhusela ikamva labo

Isiko ukulondoloza amanzi ngenxa yezizathu ezithile, akukho phantse zonke iimbombo zomhlaba. Namhlanje kwi planethi 0.6-1 billion abantu bafe lunxano. Kunye noqikelelo for state yedanisayo. Kwafa emva kweminyaka 15 "eliphakathi kwaye yababuhlungu stress amanzi" aya kuhlala malunga 5.5 billion .. ilizwe lethu kwindawo yesibini phezu zolondolozo lwamanzi ehlaziyekayo emva Brazil, nto leyo enokukhokelela ekubeni lo mmandla uya kuba kwakhona into yokuhlaselwa zomkhosi, njengokuba kuye kwenzeka ngaphezu kanye.

Kunazo zonke deal with imeko amanzi e-Afrika, nto leyo ikakhulu ngenxa iimeko zemozulu. Ngokutsho UN ayikho "lisele" abantu malunga elinanye million. Abantu banyanzelwa ukuba ukonga amanzi ukuze kwezinye iindawo abalimi kufuneka iinkomo ukuxabela kakhulu, nto leyo bengenanto kusela. Ngoko ukuba ukunxanelwa kukulamba longeziwe.

EYurophu, kwaye mvanje kwilizwe lethu ngenxa yokunyuka kweefizi ukuba eziluncedo ngokuzama ukufumana imali eyongezelelweyo kubonakala kwinto yokuba kwinani zokuhlala iimitha zamanzi zafakelwa. Ezi ndlela bala cubic ezininzi kangakanani metres "bachitha" kule nyanga, kulandele bengabaveleli isantya ilitha enye. Ukunciphisa okanye ukwandisa inani cubic metres osetyenzisiweyo unokugcina okanye ukuchitha imali engaphezulu eziluncedo. Kwakhona ukunciphisa iindleko eluncedo kunokunceda lolungelelwaniso uxinzelelo lwamanzi, nto leyo kweminye imizi icwangcisiwe kwinqanaba eliphezulu kakhulu.

Uphando umdla labathengi Russian, owafunda ukuba amanzi etephini imalunga 18 eelitha ngomzuzu, kwaye imvula - malunga namashumi amabini. Ezi zikhombisi kungancitshiswa ukuba labenzi ifake nabalawuli amanzi (PBP). Umzekelo, PBP akhutshwa iilitha ezi-2 ukuya ku-9 lokuhamba kwamanzi ngomzuzu. Ngelo xesha bakhululeke ukusebenzisa iilitha ezi-6 ngomzuzu ngenxa crane kunye neelitha 9 zamanzi ngomzuzu ukuba ishawa. Kakade ke, ezi zixhobo ziya konga manzi kuphela xa zifakwa iimitha zamanzi.

Ukongeza, oluvela ukusetyenziswa kwezibonelelo lijonge ukuxhasa isixhobo ezifana imitha yamanzi. Sithabathela ingqalelo ukuba bangaphi ulwelo kakhulu (okanye ezinye izinto) baluwela ityhubhu ixesha elithile, kubandakanywa kubalwe le parameter zokusetyenziswa ngamnye. Kukholelwa ukuba ngokonyuswa ipesenti okanye iqhezu ekhulwini ngapha koshishino ukuchana womlinganiselo liya kubonelela ebalulekileyo inzuzo kwezoqoqosho. Nangona kunjalo, abasebenzi Russian lwezindlu kunye neenkonzo zoluntu le nto uzimisele ngokukhethekileyo.

izinto ezahlukeneyo ngokupheleleyo phesheya. I-United States kunye namanye amazwe Western baye bafunda ukuba ukonga amanzi hayi ngqo kuphela kodwa ngokungathanga ngqo. Abaninzi abazi ukuba amanzi amaninzi ingena ukuveliswa imveliso. Ukuze ufumane ifayibha eyenziweyo kwi umlinganiselo weetoni mnye, kuyimfuneko ukuba tirhisa iitoni 3500 yamanzi. Kuba ml 125 zewayini kufuneka 120 eelitha zamanzi (kubandakanywa ukunkcenkceshela elutyalweni kweediliya kwaye nomjikelo yonke imveliso), kunye nemveliso isonka samasi kufuna ama-5000 zamanzi. Ngoko ke, kumazwe aphuhlileyo zithande ukuba ususe inani Productions imida yayo, ukulondoloza ubutyebi zendalo, ezifana namanzi okusela acocekileyo ithatha, Kakade ke, indawo yokuqala kuphela kuba ubukhulu becala iqulathe kanye kulo mba kwaye ukuphila ngaphandle kwakhe, yaye kwiveki.
