Wake wacabanga ukuthi umuntu uthinta kanjani imifula?

Indlela abantu abayithonya ngayo imifula iyaziwa yizazi zezinto eziphilayo, futhi zikhathazeke ngokweqile ngesimo sengqondo sokungakhathaleli kwabantu. Ukukhishwa okuqhubekayo kwemfucuza emifuleni nasezilwandle, ukubhujiswa, ukungcola kwe-microflora yabo kuyathinta isimo semvelo yamanzi, kanye nempilo yomuntu. Abantu basebenzisa izandla zabo ukuze bangcolise imifula nendlala yasendlini, imfucuza, amakhemikhali.

Isimo semifula sidlulela ekuqothulweni kwenqwaba yezinhlanzi, i-crayfish, okuyizihlungi ezithile zokuhlanzwa ngamanzi. Umonakalo omkhulu wenziwa ngabazingeli, ukubeka amanetha, abahloli be-dynamite ngezinhlanzi eziningi zokudoba. Imifula isibe yimithombo yamafektri amaningi, ngenxa yalokho imifula eyomile, ukuphila kwezidalwa eziphilayo ezigeleza lapho.

Ngaphandle kwamanzi, umuntu angeke abe khona, kodwa bambalwa abantu bacabanga ukuthi ngokusebenzisa umthelela omubi emifuleni, abantu balahla ukubaluleka kwabo, ubumsulwa kanye nobungane bezemvelo. Cabanga, njengesibonelo, imifula eminingana, futhi sizoqonda ukuthi umuntu uthinta kanjani imifula.

Ukusetshenziswa koMfula i-Inya

I-Inya yi- tributary efanele ye-Ob. Esigodini somfula kunabantu abaningi abadala, izikhukhula zezikhukhula. Ngenxa yamanzi i-reservoir isekelwe, lapho izinhlanzi eziwusizo ezibalulekile, ogwini lwaseLovovo Sea kukhona indawo yokuzilibazisa. Ama-tributary amaningi aqhubekela e-Inyu avela emanqabeni, i- Salair ridge. Emfuleni kune-burbot, pike, perch. Kodwa amabhizinisi omayini wezimayini eseduze asungula ukuqhuma kwamadwala, ukuthuthukiswa kwezimayini kwakha umthwalo we-anthropogenic kwi-Inyu, futhi lapho izindawo ezinhle kakhulu ziphenduke zibe yizidakamizwa nge-waste, plums ezingcolile. Kukhona ukungcoliswa kancane kancane komfula, ukwakheka koqweqwe lwezilwane ezinambuzane, izinsimbi ezinzima.

I-Inja ihlale isiza abantu ekukhuleni izitshalo, okwenza ugesi, ukuthutha amalahle, kodwa namuhla kufanele kuthathe izinkampani zamabhizinisi ezimboni.

Ukusetshenziswa koMfula iNeva

Ithonya lomuntu eMfuleni iNeva laqala ngokukwakhiwa kwedamu emfuleni nasekungeneni kwe-Canal Sea. Baqala ukudlula imikhumbi nama-moor cishe phakathi nendawo yedolobha. Izindawo eziningi zamafutha zivele ebhange lomfula, ikakhulukazi esifundeni saseLeningrad, cishe akukho ukuvikelwa kwemvelo. Ukudlula ukudonsa ngamabhajiki, imikhumbi kancane kancane ihambisa amanzi emanzini, amanzi asekuyisikhathi eside engasaqhathaniswa nokuhlanzeka kwangaphambili.

Ukulimaza imifula emincane eduze neMoscow

Emaphethelweni emifula, umquba, izinyoni zezinyoni, ezivela ngemuva kokubonakala kwezinkampani nezinkomo ezifuywayo, zigcinwa. Isimo esinzima namuhla sisezingeni elifanele le- Istra, uMfula iMaglush. I-floodplain igcwele amathani omquba wezinkukhu, ongathunyelwa kusuka lapho lapho iminyaka. Uma kwenzeka isishukhula, inhlekelele yangempela yemvelo ingenzeka emfuleni. Futhi izikhukhula zezikhukhula zemifula yaseMoscow kanye nesifundazwe zenziwe zingenakwenzeka ngenxa yokulima izitshalo zemifino yizakhamuzi zasehlobo, ukungcoliswa kwamanzi yizindleko zomhlaba, imfucuza yasendlini. Ukulahlwa kwemfucumfucu kukukhumbuza isikhukhula se-Istria, esinezinsalela nemifula, okuholela ekugcineni kancane kancane. Eduze emifuleni yanyathela utshani, izihlahla zibhujiswa. Namuhla, izakhamuzi zendawo "zishaya zonke izinsimbi" ukuthi sekuyisikhathi sokubuyisela ukuhlanzeka kwemifula, izikhukhula, kungenjalo esikhathini esizayo esiseduze, imithombo yemvelo kanye nemasheya isongelwa inhlekelele yemvelo egcwele. Ithonya lomuntu emfuleni lidala ukulimala okungenakuqhathaniswa nemvelo.

Isimo emifuleni yaseCrimea

Njengoba ukwanda komkhiqizo, ithonya lomuntu endaweni yemvelo landa . Imithombo yamanzi yemifula eminingi eCrimea namhlanje, ngenxa yendlela abantu abayithonya ngayo imifula, isesimweni esibuhlungu. Izinhlobo eziningi zezinhlanzi zezinhlanzi zisezingeni lokuqothulwa, esikhundleni sawo zivela amaxoxo, i-algae eluhlaza, okuyinto ngokukhipha oksijini okuvimbela umsebenzi ogcwele emanzini, ukungcola amanzi ngokubola kwawo.

Isimo sezinto eziphilayo zemifula yaseCrimea asikwanelisi nanamuhla. Kuyaphuthuma ukuhlanza amachibi, amachibi, ukuthuthwa kwamanzi. Ukuze wenze lokhu, kubalulekile ukuvuselela izitshalo zokwelashwa kwamanzi okuthuthwa kwamanzi, sebenzisa ubuchwepheshe obuqhubekayo bokunakekelwa kwamanzi angcolile, ukuqhuba inkulumo-ze echazayo phakathi kwabantu, kanye nomsebenzi wezemfundo phakathi kwezingane nentsha.

Ukusetshenziswa koMfula iYenisei

Ukususwa kwemithombo yamanzi yomfula kwenzeka njalo. Futhi ukugeleza kwamanzi kwamabhizinisi kanye nokuthuthwa komkhumbi komphakathi kuthinta kanjani umfula? Lokhu kwaholela ekwephuleni kokulingana kwemvelo yonke indawo, ukuphulukiswa kwempahla yamanani enenani eliyigugu. Ukucwilisa okuvela emasimini kuqukethe i-toxins, ukuba khona kwe-nitrogen ne-phosphorus kuzo zonke amarekhodi ezinqwaba. Amakhuphu amaningi abola, ukutheleleka kwezinhlanzi kwenzeka.

Isiphetho

Akungabazeki ukuthi impendulo yombuzo wokuthi umuntu uthinta kanjani imifula. Omunye angasho ukuthi kubi kakhulu, ukubhubhisa usuku nosuku izitshalo nezilwane zemifula namachibi ngezandla zabo.

Ngobugebengu bomuntu, ukuhaha, ukunganaki kwezemvelo kumele kulwa njalo. Imizimba yamanzi yasemadolobheni ingcolile ngotshwala, imfucuza, amakhemikhali. Ukuphila kwangaphansi kwamanzi kancane kancane kuqothulwa, lokhu kubuye kube lula ngokuba khona kwabadobi abaningi, abazingeli, abahlela amanethiwekhi abo, abahloli be-dynamite.

Amanzi ngumthombo wokuphila. Leli gama liye lalahlekelwa incazelo yalo. Imvelo nemifula iba mnandi kakhulu, futhi konke okuvela engozini eyenziwa ngumuntu. Abantu abaningi bazi ukuthi abantu bathinta kanjani imifula namachibi. Yiqiniso, kubi kakhulu. Ukuze silwe nokulondolozwa kwezinsiza, ukubuyiswa kwazo kuyadingeka yonke indawo, ngemizamo evamile, ngaphandle kwalokho imifula namachibi aseduze kuyoba yize, futhi izinhlobo eziningi zezinhlanzi ziyophela.
