Kuninzi okutshiweyo malunga nefuthe lokushisa komhlaba, mva nje ngokungathi yinto engalunganga, into enokubangela iingxaki ezininzi ebantwini nakwezinye izinto eziphilayo ezihlala kuMhlaba. Kodwa ngaba siyayazi ukuba ibangelwa yintoni kwaye ibaluleke kangakanani ebomini?
Emva koko ndiza kuchaza yintoni kwaye yintoni ebangela isiphumo sokugcina ukuze, ngale ndlela, ube nokuqonda kancinane ngakumbi ngesijikelezi-langa esisichukumisileyo.
Iyintoni umphumo wegreenhouse?
Yinkqubo eyenziwayo Imitha ekhutshwa elangeni ifunxwa zii-greenhouse gases o I-GHG (umphunga wamanzi, icarbon dioxide, imethane, i-nitrogen oxide, i-ozone kunye ne-chlorofluorocarbons) ifumaneka emoyeni kwaye ikhanya kumacala onke. Eminye yale radiation ifunxwa ngumphezulu woMhlaba, ukuze ubushushu bomgangatho ophakathi bunyuke, buvumele ubomi ukuba bubekhona.
Nangona kunjalo, imisebenzi yabantu iye yaqinisa le nkqubo yendalo, ngaloo ndlela kwandisa ubushushu behlabathi.
Ineziphi iziphumo?
Impembelelo yendalo yendalo eluhlaza ivumele ubomi njengoko sibazi ukuba bukhona kwaye bukhula; Nangona kunjalo, njengabantu abagawula amahlathi, basebenzisa izibaso, bangcolisa kwaye, ekugqibeleni, bangawukhathaleli umhlaba, uxinizelelo lwe-GHGs, ngakumbi icarbon dioxide, lonyukile.
Ngenxa yoko, imitha emininzi ibuyiselwa ngaphezulu, ibangela ukwanda kweqondo lobushushu, i ukunyibilika komkhenkce osemkhenkceni, onokuthi ubangele ukuba ulwandle lukhuphuke, i inkqantosi , utshintsho kumaxesha onyaka, kwaye utshintsho kwiipatheni zemvula.
Iziphumo zendlu eluhlaza (greenhouse effect) yinkqubo emele ukuhlala iyindalo. Ke ngoko, kubalulekile ukuyeka ukutshabalalisa iplanethi.
Enkosi ngokusinika izihloko ezininzi ezinomdla kakhulu, kuba oku kuya kusinceda ukuba sibe nolwazi malunga nomonakalo kwiplanethi yethu kunye nenkathalo kunye namanyathelo ekufuneka siwathathe.
Kuyimfuneko ukuchaza izizathu abazibonayo namhlanje ????????????
