“Akuyona Isayensi Kababa Wami”: Mina no-Alanna Mitchell Sixoxa Amandla Ethiyetha kanye Nolwandle Olushintshayo

“Ukube yonke into esemhlabeni ibingafa kusasa, konke olwandle bekuzolunga. Kodwa uma konke okusolwandle kungafa, yonke into esemhlabeni nayo ingafa.”

U-ALANNA MITCHELL | IZINTATHELI ZESAYENSI ESIYASEKHANA ELAWINA Imiklomelo

U-Alanna Mitchell umi endaweni encane emnyama, enkabeni yesiyingi esimhlophe esidwetshwe ngoshoki esingamafidi angu-14 ububanzi. Ngemva kwakhe, ibhodi liphethe igobolondo lasolwandle elikhulu, ucezu lukashoki, nerabha. Kwesokunxele, kunetafula elinengilazi elinembiza kaviniga nengilazi eyodwa yamanzi. 

Ngibukele ngithule kanye nabanye abalaleli bami, sihlezi esihlalweni esisesikhungweni se-Kennedy Centre's REACH plaza. Umbukiso wabo we-COAL + ICE, umbukiso wezithombe oyidokhumentari obonisa umthelela ojulile wokushintsha kwesimo sezulu, uvala isiteji futhi wengeza ungqimba oluthusayo emdlalweni wowesifazane oyedwa. Kwesinye isikrini seprojektha, kubhonga umlilo endaweni evulekile. Esinye isikrini sibonisa ukubhujiswa okuhamba kancane nokuqinisekile kwamaqhwa e-Antarctica. Futhi maphakathi nakho konke, u-Alanna Mitchell uyama futhi asixoxele indaba yokuthi wathola kanjani ukuthi ulwandle luqukethe umshini wokuphila konke emhlabeni.

“Angiyena umlingisi,” kuvuma uMitchell kimi emahoreni ayisithupha nje ngaphambili, phakathi kokuhlolwa komsindo. Simi phambi kwesinye sezikrini zombukiso. Ukuqonda kweSiphepho u-Irma ku-Saint Martin ngo-2017 kugeleza ku-loop ngemuva kwethu, izihlahla zesundu zizamazama emoyeni kanye nezimoto eziguquguqukayo ngaphansi kwesikhukhula esinamandla. Kuhluke kakhulu ekuziphatheni kuka-Mitchell okuzolile nethemba.

Eqinisweni, uMitchell's I-Sea Sick: I-Global Ocean in Crisis kwakungafanele neze kube umdlalo. UMitchell waqala umsebenzi wakhe wokuba yintatheli. Ubaba wakhe wayengusosayensi, ebhala amathafa aseCanada futhi efundisa izifundo zikaDarwin. Njengokulindelekile, uMitchell wahlabeka umxhwele ngendlela izimiso zeplanethi yethu ezisebenza ngayo.

“Ngaqala ukubhala ngomhlaba nomkhathi, kodwa ngase ngikhohliwe ngolwandle.” Kuchaza uMitchell. “Ngangingazi ngokwanele ukuba ngibone ukuthi ulwandle luyingxenye ebalulekile yalo lonke uhlelo. Ngakho lapho ngikuthola, ngisanda kuqalisa lonke lolu hambo lweminyaka ngibuza nososayensi ngokwenzeka olwandle.” 

Lokhu kutholakala kwaholela uMitchell ukuba abhale incwadi yakhe ULwandle Olugulayo ngo-2010, mayelana namakhemikhali ashintshiwe olwandle. Ngenkathi esohambweni exoxa ngocwaningo nothando lwakhe ngencwadi, wahlangana noMqondisi Wezobuciko Franco Boni. “Futhi wathi, uyazi, 'Ngicabanga ukuthi lokho singakushintsha kube umdlalo.'”. 

Ngo-2014, ngosizo lwe Isikhungo Seshashalazi, ezinze eToronto, kanye nabaqondisi ababambisene nabo uFranco Boni kanye Ravi Jain, Ukugula kolwandle, umdlalo, wethulwa. Futhi ngoMashi 22, 2022, ngemuva kweminyaka yokuvakasha, ULwandle Olugulayo yaqala ukuvela e-US Kennedy Centre eWashington, DC. 

Njengoba ngimi no-Mitchell futhi ngivumela izwi lakhe elipholile ligeze phezu kwami ​​- naphezu kwesiphepho esikrinini sombukiso ngemuva kwethu - ngicabanga ngamandla etiyetha ukufaka ithemba, ngisho nangezikhathi zesiphithiphithi. 

“Kuwubuciko obusondelene ngendlela emangalisayo futhi ngiyayithanda ingxoxo eyivulayo, enye ingakhulunywa, phakathi kwami ​​nabalaleli,” kusho uMitchell. “Ngikholelwa emandleni obuciko okushintsha izinhliziyo nezingqondo, futhi ngicabanga ukuthi umdlalo wami unikeza abantu umongo wokuqonda. Ngicabanga ukuthi mhlawumbe kusiza abantu ukuba bathande iplanethi. "

E-REACH plaza, uMitchell usikhumbuza ukuthi ulwandle luwuhlelo lwethu oluyinhloko lokusekela ukuphila. Lapho amakhemikhali ayisisekelo olwandle eshintsha, lokho kuyingozi yazo zonke izinto eziphilayo emhlabeni. Uphendukela ebhodini lakhe njengoba ingoma ka-Bob Dylan ethi “The Times They Are A-Changin'” inanela ngemuva. Uqopha uchungechunge lwezinombolo ezingxenyeni ezintathu ukusuka kwesokudla kuye kwesokunxele, futhi alebule ukuthi “Isikhathi,” “Ikhabhoni,” kanye “ne-pH”. Uma uthi nhlá, izinombolo zikhulu kakhulu. Kepha njengoba uMitchell ephenduka ezochaza, iqiniso liyamangaza nakakhulu. 

“Eminyakeni engu-272 nje kuphela, siye saqhubekisela phambili ukwakheka kwesimiso sokusekela ukuphila kweplanethi ezindaweni ebingakaze ibe kuzo amashumi ezigidi zeminyaka. Namuhla, sine-carbon dioxide eningi emkhathini kunalokho ebesinakho okungenani iminyaka eyizigidi ezingu-23… Futhi namuhla, ulwandle lune-asidi kakhulu kunalokho obekuyikho iminyaka eyizigidi ezingu-65.” 

“Lelo iqiniso elithusayo,” ngitshela uMitchell ngesikhathi ehlola umsindo, okuyiyona ndlela uMitchell afuna izilaleli zakhe zisabele ngayo. Uyakhumbula efunda incwadi umbiko omkhulu wokuqala mayelana ne-acidification yolwandle, ekhishwe yiRoyal Society yaseLondon ngo-2005. 

“Kwakudabukisa kakhulu. Akekho owayazi ngalokhu,” uMitchell uyathula bese emamatheka kancane. “Abantu bebengakhulumi ngayo. Bengisuka kwesinye isikebhe socwaningo ngiya kwesinye, futhi laba ngososayensi abaqavile, futhi bengithi, 'Yilokhu engisanda kukuthola,' bese bethi '...Ngempela?'”

Njengoba uMitchell ebeka, ososayensi bebengazihlanganisi zonke izici zocwaningo lwasolwandle. Kunalokho, bafunda izingxenye ezincane zaso sonke isimiso solwandle. Babengakazi ukuthi bazixhuma kanjani lezi zingxenye emkhathini wethu womhlaba. 

Namuhla, isayensi ye-acidification olwandle iyingxenye enkulu kakhulu yezingxoxo zamazwe ngamazwe kanye nohlaka lwendaba yekhabhoni. Futhi ngokungafani neminyaka engu-15 edlule, ososayensi manje bacwaninga ngezidalwa ezisendaweni yazo yemvelo futhi baxhumanisa lokhu okutholakele kulokho okwenzeka emakhulwini ezigidi zeminyaka edlule - ukuze bathole amathrendi futhi bavuse amaphuzu avela ekuqothulweni okukhulu kwangaphambilini. 

Ububi? “Ngicabanga ukuthi siya ngokuya siqaphela ukuthi iwindi lincane kangakanani ukwenza umehluko futhi sivumele impilo njengoba sazi ukuthi iqhubeke,” kuchaza uMitchell. Uyabalula emdlalweni wakhe, “Lena akuyona isayensi kababa. Ngosuku lukababa, ososayensi babethatha umsebenzi wonke bebheka isilwane esisodwa, ukuthola ukuthi sinabantwana abangaki, esidlani, ukuthi sichitha kanjani ubusika. Beku… ngokunethezeka.”

Pho, yini esingayenza? 

“Ithemba wuhlelo. Akulona iphuzu lokugcina.”

U-ALANNA MITCHELL

"Ngithanda ukucaphuna usosayensi wesimo sezulu wase-Columbia University, igama lakhe u-Kate Marvel," uMitchell uyathula umzuzwana ukuze akhumbule. “Okunye akushilo mayelana nomjikelezo wakamuva wemibiko evela kwi-Intergovernmental Panel on Climate Change ukuthi kumqoka ngempela ukubamba imibono emibili ekhanda lakho ngesikhathi esisodwa. Enye ukuthi kungakanani okusazokwenziwa. Kodwa okunye ukuthi sesihambe kangakanani, vele. Futhi yilokho engize kukho. Kimina ithemba liwuhlelo. Akulona iphuzu lokugcina.”

Kuwo wonke umlando wokuphila emhlabeni, lesi yisikhathi esingajwayelekile. Kodwa ngokukaMitchell, lokhu kusho nje ukuthi sisesigabeni esiphelele sokuziphendukela kwemvelo kwabantu, lapho “sinenselele emangalisayo futhi sithola ukuthi singabhekana kanjani nayo.”

“Ngifuna abantu bazi ukuthi empeleni yini esengozini nokuthi senzani. Ngoba ngicabanga ukuthi abantu bayakhohlwa ngalokho. Kodwa futhi ngicabanga ukuthi kubalulekile ukwazi ukuthi awukapheli umdlalo. Sisenesikhathi sokwenza izinto zibe ngcono, uma sikhetha ukwenza njalo. Yilapho imidlalo yeshashalazi nobuciko kungena khona: ngikholwa ukuthi wumfutho wamasiko ozosiyisa lapho sidinga ukuya khona.”

Njengesisekelo somphakathi, i-Ocean Foundation izazi kuqala izinselelo ekuqwashiseni umphakathi ngezindaba ezithinta umhlaba wonke ngenkathi inikeza izixazululo zethemba. Ubuciko budlala indima ebalulekile ekuhumusheni isayensi ezithamelini okungenzeka zifunda ngodaba okokuqala ngqa, futhi i-Sea Sick yenza lokho kanye. I-TOF iyaziqhenya ngokusebenza njengozakwethu we-carbon offsetting ne-Theatre Centre ukuze isekele ukongiwa kwendawo ehlala ugu nokubuyiselwa.
