Umphumela wokukhishwa okungalawuleki kwemikhiqizo yomsebenzi womnotho womuntu emkhathini uye waba ngumthelela wokushisa okushisa, okucekela phansi ungqimba lwe-ozone loMhlaba futhi kuholele ekufudumaleni kwembulunga yonke emhlabeni. Ngaphezu kwalokho, kusukela ebukhoneni bezinto ezisemoyeni ezingafani nazo, inani lezifo zomdlavuza ezingalapheki likhula ngejubane le-cosmic.
Izinhlobo zemithombo yokungcola
Imithombo yokufakelwa (i-anthropogenic) yokungcola komoya idlula eyemvelo ngamashumi ezigidi zezikhathi futhi idala ukulimala okungenakulungiseka kuzo zombili imvelo kanye nempilo yabantu. Zihlukaniswe zaba:
- ezokuthutha - ezakhiwe ngenxa yomlilo wephethiloli ezinjinini zangaphakathi zomlilo kanye nokukhishwa kwesikhutha emkhathini. Umthombo walolu hlobo lokungcola yizo zonke izinhlobo zezinto zokuhamba ezisebenzisa uphethiloli oketshezi;
- izimboni - ukukhishwa emkhathini kwemiphunga egcwele izinsimbi ezisindayo, izinto ezinemisebe eyingozi kanye namakhemikhali akhiqizwe ngenxa yokusebenza kwezitshalo nezimboni, izitshalo zamandla nezitshalo zamandla ezishisayo;
- Umndeni - ukusha okungalawuleki kwemfucuza (amaqabunga awile, amabhodlela epulasitiki nezikhwama).
Ukulwa nokungcola kwe-anthropogenic
Ukwehlisa inani lokukhishwa kanye nokungcola, amazwe amaningi athathe isinqumo sokwakha uhlelo oluchaza izibopho zombuso zokwehlisa noma ukukhuphula izindawo zokukhiqiza ezingcolisa umoya - iKyoto Protocol. Ngeshwa, ezinye zezibopho zihlala emaphepheni: ukunciphisa inani lokungcola komoya akunanzuzo kubanikazi abakhulu bamabhizinisi amakhulu ezimboni, njengoba kufaka ukwehliswa okungenakugwemeka komkhiqizo, ukwanda kwezindleko zokuthuthukisa nokufaka izinhlelo zokuhlanza nokuvikela imvelo. Amazwe afana neChina neNdiya enqabile ukusayina lo mbhalo ngokuphelele, ecacisa ngokushoda kwemikhiqizo emikhulu yezimboni. ICanada neRussia benqabile ukuqinisekisa umthetho olandelwayo endaweni yabo, bexoxisana ngama-quota namazwe ahola ekukhiqizeni izimboni.
Iziza ezinkulu zokulahla udoti ezungeze amadolobha amakhulu njengamanje zigcwele kakhulu udoti wepulasitiki. Ngezikhathi ezithile, abanikazi abangathembekile bokulahlwa kukadoti okulahlekile kukadoti wasekhaya bashisa lezi zintaba zemfucumfucu, futhi i-carbon dioxide ihanjiswa ngenkuthalo emoyeni ngomusi. Isimo esifanayo singasindiswa ngokuvuselelwa kwezitshalo, ezintula kakhulu.
