Ngawo-70, intshisekelo yomphakathi yayigxile ekukhuleni kwenani labantu emhlabeni kanye nokukhathazeka okukhulayo ngezinsizakusebenza ezitholakalayo ukuhlangabezana nezidingo ezandisiwe. Udaba ngaleso sikhathi lwalahleka ngokubaluleka okukhulu, kepha uma kubhekwa ukuvela kobuchwepheshe nokwanda okungalingani kwabantu, sekuyisikhathi sokubuyela odabeni. Futhi ngukuthi sezivele zilungisiwe imikhawulo yokukhula ngemuva kukawoyela ophakeme kubangelwa ukusetshenziswa kabi kwe- imithombo yemvelo nokuxhashazwa kwezinqolobane zikawoyela nokunye izinto zokubasa.
Kule ndatshana sizocubungula ngesimo somhlaba nobudlelwano phakathi kwemikhawulo yokukhula namandla omphakathi okuhlinzeka abantu.
Ukwanda kwenani labantu emhlabeni
Inani labantu liphindaphindeke kabili eminyakeni engamashumi amane kuphela. Yize ubumpofu bujezisa izifunda ezithile zomhlaba, indlala ejwayelekile iye yagwenywa ngenxa yokusetshenziswa kwamandla okubasa. Lokhu kuvumela ukutholakala kokudla okuningi yize kungcolisa umhlaba kakhulu futhi kuveza imiphumela emibi njengokushintsha kwesimo sezulu.
Ezolimo zidlala indima ebalulekile kuyo yonke imikhakha yokukhiqiza ukudla futhi izindlela zokuthola izitshalo ziyizimo zokuqinisekisa ukuthi ukungcola kuyaqhubeka noma cha. Ngalokhu, inqubo yezolimo esimeme noma yokongiwa isungulwe okuhlose ukunciphisa imithelela ekungcoleni kwenhlabathi namanzi ukuze izakhamzimba esizithola ngokuvuna zibe sezingeni elingcono futhi zingangcolisi. Konke lokhu kwenziwa ngenhloso yokwenza i- ukudla okusimeme emhlabeni jikelele ukuqinisekisa ukuthi izinsizakusebenza esizisebenzisa namuhla zingasetshenziswa nayizizukulwane ezizayo ezizayo.
Ngenxa yokuthuthukiswa kobuchwepheshe, ingxenye enkulu yokufuduka kwabantu basemaphandleni kanye nokunethezeka kwamamodeli ahlukahlukene amadolobha amile, ingxenye enkulu yabantu emhlabeni ingahlaliswa endaweni encane. Lokhu uthanda ukunciphisa amabanga okumele ambozwe ukuthuthwa kwempahla eluhlaza kanye nemikhiqizo, ukuhlushwa kwezimboni nokukhiqizwa kukagesi okuphakathi.
Ngakolunye uhlangothi, sinokuningi ngokweqile ekusetshenzisweni kwemithombo yemvelo enjengokhuni, uwoyela, igesi yemvelo namalahle. Lokhu kuxhashazwa ngokweqile kubuye kuchazwe kwezinye izinto eziphilayo ezifana ne- ezolimo ezifuywayo nemfuyo, ukudoba ngokweqile noma ukumbiwa phansi. Konke lokhu kuholela ekonakaleni kwemithombo yemvelo, ukwanda kokungcola kwemvelo kuzo zonke izici ngakho-ke, ushintsho ekuguquguqukeni kwesimo sezulu okwenzeka emhlabeni wonke.
Imikhawulo yokukhula
Ochwepheshe bezomnotho sebevele bakusho emuva ngonyaka we-1972, ngenkathi kushicilelwa umbiko othi "Limits to Growth". Inani labantu emhlabeni lalingabe seliphakela sonke isidingo sokudla namandla esiqongweni samafutha. Inkinga yemvelo yango-1960 yaqeda isigaba sezinkinga zemvelo lapho kwakungatshazwa khona ukuthi uwoyela, kanye nawo wonke amanye amandla okubasa Bengeke bakwazi ukondla ukuthuthukiswa kobuchwepheshe ngenxa yokukhathala kwabo okuseduze.
Eminyakeni edlule, ngokufika kwamandla avuselelekayo, kucatshangwa ukuthi umhlaba uyakwazi ukwakha abantu abaningi ngenxa yokukhiqizwa kwamandla ngezinto zemvelo ezifana nelanga, amanzi, umoya, i-biomass, amandla we-geothermal namandla akhishwa kumagagasi. Kodwa-ke, i-utopia yokwakha umhlaba kusuka kumandla angenamkhawulo ahlanzekile ishaye udonga olukhulu lokusebenzisa kahle amandla.
La ukusebenza kahle kwamandla Izama ukukhiqiza isitokisi samandla esiphezulu ngentengo ephansi kakhulu yezindleko. Lokhu kusho ukuthi ingxenye enkulu yotshalo-mali lwe-R & D ibhekiswe kulezi zindawo, kwehlisa ukubaluleka kokubasa kukaphethiloli. Ingcindezi evela kohulumeni nemiphakathi yezemvelo enjengeGreenpeace noma i-Ecologists in Action ikhalela amandla avuselelekayo ukuba axhaswe futhi athuthukiswe ebusweni bomhlaba ofuna amandla futhi izinga lokushisa lomhlaba wonke elijwayelekile likhuphuka ngaphezu kwalokho obekuhlongozwayo osukwini lwalo njengoba “Kuyingozi” emibikweni ye-Intergovernmental Panel on Climate Change (IPCC).
Unyawo lweCarbon
Kunemithombo eminingi yemvelo esevele idlule ubukhulu bayo emashumini eminyaka amuva nje. Futhi yilokho izinga lokusetshenziswa lidlula kakhulu lelo lokukhiqiza futhi, ngaphezu kwakho konke, lelo lezinqolobane. Njengoba izinsuku zokuphela kwamandla okubasa ezinjenge oyili, igesi yemvelo kanye namalahle sezivele sezimisiwe, okusele ukuqhubeka ukuqhubeka nokwakha amandla avuselelekayo ukugcina ijubane lempilo esinalo namuhla.
Umkhondo wekhabhoni uyinkomba yenani le- isikhutha lokho kukhishwa yisakhamuzi nangophiko lobuso. Kusho ukuthi, ukwanelisa isidingo sethu, sokudla, kanye namandla, izimpahla kanye nezinsizakalo, sidinga ukukhipha isikhutha emkhathini. Lapho ukusetshenziswa kwethu kukhulu, amathani akhishwa kakhulu.
Ukwenza isibonelo salokhu, sicabanga ukuthi sinamakhaya ethu, sidla ukudla okuthile, sisebenzisa ikhompyutha, ithelevishini, siyageza, silalela umculo, sizithuthe ngemoto yethu yangasese, njll. Ukuze senze zonke izinto ezisizungezile ezimpilweni zethu, kudingeke ukuthi sisebenzise impahla eluhlaza engcolisiwe. Ngakho-ke, okunyatheliswa ngekhabhoni kukhulu kakhulu umcebo esinawo futhi kuhlobene kakhulu nomholo womuntu ngamunye womuntu ngamunye. Lapho unamandla okuthenga athe xaxa, kukhishwa ikhabhoni eningi emkhathini.
Ukulingana ngaphambi kwakho konke?
Uma siqhathanisa umkhondo wekhabhoni wabantu abasemazweni asathuthuka, siyabona ukuthi kunabantu abaningi ngokwengeziwe kepha abanendawo encane yekhabhoni kumhlali ngamunye. Okusho ukuthi ingxenye encane yabantu emhlabeni ibhekele ukungcola okuningi kweplanethi.
Kungani ama-80% wabantu bomhlaba kufanele bakhokhe imiphumela yezinhlekelele eziningi zezulu ezibangelwe ukungcola kwamanye ama-20%? Ohulumeni babiza ukulingana nokungakhethi, kepha iqiniso lisho okuningi ukufeza lezo zinhloso.
Okwamanje, umhlaba usufinyelela imikhawulo yokukhula futhi ikusasa aliqinisekile ngokuphelele. Ngiyethemba ukuthi le ndatshana ikwenza ucabange ngodaba lokulingana emhlabeni nokusetshenziswa ngokweqile kwezinsizakusebenza.
