Ukupholisa umhlaba kanjani
Isimo sezulu soMhlaba siya ngokufudumele. Umuntu angaphikisana, okokuqala ngumuntu noma izizathu eziyinhloko kufanele zifunwe kwenye indawo. Nokho, izilinganiso ezinembile ezenziwa emashumini ambalwa eminyaka azinakuphikwa? izinga lokushisa ku-biosphere liya ngokuya likhuphuka, futhi iqhwa elimboze isifunda saseNorth Pole lancibilika laba usayizi ophansi orekhodiwe ehlobo lika-2012.
Ngokusho kwedatha eshicilelwe yi-German Institute for Renewable Energy, ukukhishwa kwe-anthropogenic ye-CO2, igesi ethathwa njengengxenye enkulu ekushintsheni kwesimo sezulu esibi, ifinyelele irekhodi lamathani ayizigidi eziyizinkulungwane ezingu-2011 kuma-34. Ngokulandelayo, i-International Meteorological Organization yabika ngoNovemba 2012 ukuthi umkhathi woMhlaba usuvele unezingxenye ezingu-390,9 esigidini se-carbon dioxide, okuyizingxenye ezimbili eminyakeni eyishumi edlule, kanye no-40% ngaphezu kwezikhathi zangaphambi kwezimboni.
Imibono imi kanje: izifunda ezisogwini ezivundile ngaphansi kwamanzi, amadolobha aphelele nanomsindo agcwele izikhukhula. Indlala kanye nezigidi zababaleki. Izinhlekelele zemvelo ezinamandla angakaze abonwe. Amazwe anesimo sezulu esipholile, anamanzi amaningi, adlulela ezindaweni ezishisayo ezomile neziwugwadule. Izifunda ezomile zaminza ezikhukhuleni zaminyaka yonke.
Namuhla, imiphumela enjalo yokushintsha kwesimo sezulu kuxoxwa ngayo ngokungathi sína. Icala lingase lisho ukuwa kwempucuko ezindaweni ezinkulu zomhlaba. Ngakho-ke akumangazi ukuthi amaphrojekthi we-geoengineering anesibindi, kwesinye isikhathi azwakala kamnandi abezilungiselela ukumisa ukufudumala komhlaba.
Ukugeleza kwemibono
Imibono yokupholisa umhlaba wonke? engaphuthelwa. Eziningi zazo zigxile ekuboniseni imisebe yelanga. Abanye abantu bafuna ukwenza mhlophe? amafu abafutha ngesifutho sikasawoti. Imibono eminingi yamafu? kungamagciwane akhiqiza ngaphezulu kwawo noma avule amafu okwenziwa kumabhaluni. Abanye bafuna ukuphinda bagcwalise i-stratosphere Yomhlaba ngezinhlanganisela zesulfure ukuze lolu ungqimba lubonise kangcono imisebe yelanga. Ngisho namaphrojekthi afisa ukuvelela abandakanya ukubeka isistimu yesibuko emzileni ozungeza uMhlaba ongagudluza futhi ngokunokwenzeka ufihle izindawo ezinkulu zeplanethi.
Kukhona futhi imiklamo yoqobo eyengeziwe. Abanye abantu baphupha ngezinhlobo zezitshalo ezinemibala enobunjiniyela bofuzo ukuze izindawo ezinkulu zazo zibonise kangcono imisebe yelanga. Ifilimu abanye babadali abahlose ukulifaka ezindaweni eziwugwadule emhlabeni wethu lingaba nenjongo nomthelela ofanayo.
