Ubuso obukhulu bomhlaba buhlanganiswe ngamanzi, okwakha lonke ulwandle lomhlaba. Kunemithombo emisha yamanzi emhlabathini - emachibini. Imifula iyimithambo yokuphila yamadolobha amaningi namazwe amaningi. Izilwandle zondla abantu abaningi. Konke lokhu kusikisela ukuthi akunakuphila emhlabeni ngaphandle kwamanzi. Kodwa-ke, umuntu uyayilahla insiza eyinhloko yemvelo, eholele ekungcolisweni okukhulu kwe-hydrosphere.
Amanzi ayadingeka empilweni hhayi kubantu kuphela, kodwa nasezilwaneni nasezitshalweni. Ngokusebenzisa amanzi, ukungcolisa, konke okuphilayo emhlabeni kuhlaselwa. Imithombo yamanzi eplanethi ayifani. Kwezinye izingxenye zomhlaba kunamanzi anele, kanti kwezinye amanzi aswele kakhulu. Ngaphezu kwalokho, abantu abayizigidi ezintathu bafa unyaka nonyaka ngenxa yezifo ezibangelwa ukuphuza amanzi asezingeni eliphansi.
Izizathu zokungcola kwemizimba yamanzi
Njengoba amanzi angaphezulu angumthombo wamanzi ezindaweni eziningi, isizathu esiyinhloko sokungcola kwemizimba yamanzi umsebenzi we-anthropogenic. Imithombo esemqoka yokungcola kwe-hydrosphere:
- amanzi angcolile endle;
- umsebenzi weziteshi zokuphehla ugesi ophehlwa ngamanzi;
- amadamu nezindawo zokugcina amanzi;
- ukusetshenziswa kwe-agrochemistry;
- izinto eziphilayo;
- ukugeleza kwamanzi ezimbonini;
- ukungcoliswa kwemisebe.
Vele, uhlu alupheli. imvamisa imithombo yamanzi isetshenziselwa noma iyiphi injongo, kepha ngokulahla amanzi angcolile emanzini, awahlanzwa nokuhlanzwa, futhi izinto ezingcolisayo zisabalalisa ibanga futhi zijulise isimo.
Ukuvikelwa kwamachibi angcolisiwe
Isimo semifula namachibi amaningi emhlabeni sibucayi. Uma ukungangcoliswa kwemizimba yamanzi kungamiswa, izinhlelo eziningi ze-aqua zizoyeka ukusebenza - ukuzihlanza uqobo nokunikeza impilo ezinhlanzini nakwabanye abahlali. Kubandakanya, abantu ngeke babe nezinqolobane zamanzi, okuzoholela ekufeni.
Ngaphambi kokuba kwephuze kakhulu, amadamu kumele avikelwe. Kubalulekile ukulawula inqubo yokukhishwa kwamanzi nokusebenzisana kwamabhizinisi ezimboni ngemizimba yamanzi. Kuyadingeka kumuntu ngamunye ukonga imithombo yamanzi, ngoba ukusetshenziswa kwamanzi ngokweqile kunomthelela ekusetshenzisweni kwawo amaningi, okusho ukuthi imizimba yamanzi izongcola kakhulu. Ukuvikelwa kwemifula namachibi, ukulawula ukusetshenziswa kwezinsizakusebenza kuyindlela edingekayo ukuze kugcinwe ukuhlinzekwa kwamanzi okuphuza ahlanzekile emhlabeni, kubalulekile empilweni yawo wonke umuntu, ngaphandle kokukhetha. Ngaphezu kwalokho, kudinga ukwabiwa okunengqondo ngokwengeziwe kwemithombo yamanzi phakathi kwezindawo zokuhlala ezihlukene nezifundazwe zonke.
