Ukuthuthukiswa kwezimboni akukhona nje kuphela ukuqinisa umnotho, kodwa futhi nokungcola kwezwe eliseduze. Izinkinga zemvelo sezibe semhlabeni wonke esikhathini sethu. Isibonelo, kule minyaka eyishumi edlule, inkinga yokushoda kwamanzi okuphuza ibiphuthuma. Kusenezinkinga zokungcola komkhathi, inhlabathi, amanzi anenqwaba yezimboni kanye nokukhishwa. Ezinye izinhlobo zezimboni zifaka isandla ekubhujisweni kwezitshalo nezilwane.
Khulisa ukukhishwa okuyingozi emvelweni
Ukwanda kwenani lomsebenzi nenani lemikhiqizo ekhiqizwayo kuholela ekusetshenzisweni okwandisiwe kwemithombo yemvelo, kanye nokwanda kokukhishwa okuyingozi emvelweni. Imboni yamakhemikhali ibeka usongo olukhulu emvelweni. Izingozi eziyingozi, imishini ephelelwe yisikhathi, ukungalandelwa kwemithetho yezokuphepha, amaphutha okuklama nokufaka. Izinhlobo ezahlukahlukene zezinkinga ebhizinisini zenzeka ngenxa yephutha lomuntu. Ukuqhuma nezinhlekelele zemvelo kungaba yimiphumela.
Imboni kawoyela
Usongo olulandelayo yimboni kawoyela. Ukukhishwa, ukucutshungulwa kanye nokuthuthwa kwensiza yemvelo kunomthelela ekungcoleni kwamanzi nenhlabathi. Omunye umkhakha wezomnotho olulaza imvelo yizimboni kaphethiloli namandla kanye nezinsimbi. Ukukhishwa kwezinto ezinobungozi kanye nodoti ongena emkhathini nasemanzini kulimaza imvelo. Isimo semvelo noqweqwe lwe-ozone kuyabhujiswa, imvula ene-asidi iyawa. Imboni yokukhanyisa nokudla nayo ingumthombo oqhubekayo wemfucuza enobungozi engcolisa imvelo.
Ukucubungula izinkuni izinto zokusetshenziswa
Ukugawulwa kwezihlahla nokucutshungulwa kwezinto ezisetshenzisiwe ngokhuni kubangela umonakalo omkhulu emvelweni. Ngenxa yalokhu, akukhona nje kuphela inani elikhulu lemfucuza elenziwe, kodwa futhi nenani elikhulu lezitshalo libhujiswa. Ngokulandelayo, lokhu kuholela eqinisweni lokuthi ukukhiqizwa komoya-mpilo kuyehla, inani le-carbon dioxide emkhathini liyakhula, nomphumela wokushisa okushisayo uyanda. Futhi, izinhlobo eziningi zezilwane nezinyoni ezaziphila ehlathini ziyafa. Ukungabi bikho kwezihlahla kunomthelela ekushintsheni kwesimo sezulu: izinguquko zokushisa okubukhali ziba, umswakama uyashintsha, inhlabathi iyashintsha. Konke lokhu kuholela eqinisweni lokuthi insimu iba engakulungele ukuphila komuntu, futhi baba ngababaleki bezemvelo.
Ngakho-ke, izinkinga zemvelo zomkhakha namuhla sezifike ezingeni lomhlaba jikelele. Ukuthuthukiswa kwemikhakha eyahlukahlukene yezomnotho kuholela ekungcolisweni kwemvelo nasekuqothulweni kwemithombo yemvelo. Futhi konke lokhu kungekudala kuzoholela enhlekeleleni yomhlaba wonke, ukuwohloka kwempilo yazo zonke izinto eziphilayo emhlabeni.
