Ukusefa kwasebusika

Oku kulandelayo yiblogi yeendwendwe ebhalwe nguCatharine Cooper, iBhodi ye-TOF yeLungu labacebisi. Ukufunda i-bio epheleleyo kaCatharine, tyelela yethu Iphepha loMcebisi weBhodi.

Ukusefa kwasebusika.

Ubushushu bomoya - 48 °. Ubushushu bolwandle - 56 °.

Ndigxampuza ngokukhawuleza kwisuti yam, umoya obandayo uthomalalisa ubushushu emzimbeni wam. Nditsala iibhutsi, ndehlisa umzantsi we-wetsuit ngaphezulu kweenyawo zam ezigqunywe nge-neoprene ngoku, ndongeza i-wax kwi-longboard yam, kwaye ndihlale ukuhlalutya ukudumba. Njani kwaye phi incopho itshintshe. Ixesha phakathi kweesethi. Indawo yokubheqa ngaphandle. Imisinga, iiriptides, icala oya ngakulo umoya. Ngale ntsasa, kusebusika ngasentshona.

Abaqhubi bamaphenyane banike ingqwalasela elwandle. Likhaya labo elikude nomhlaba, kwaye lihlala liziva lisekelwe ngakumbi kuneminye imihlaba. Kukho iZen yokudityaniswa namaza, amandla angamanzi aqhutywa yimimoya, ehambe amakhulu eemayile ukuya elunxwemeni. Iqhuma elidala, ubuso obubenyezelayo, ukubetha kwentliziyo ebetha ulwalwa okanye kwindawo enganzulwanga kwaye inyukela phezulu naphambili njengamandla okuntlitheka kwendalo.

Ndijonge ngaphezulu ngoku njengetywina kunomntu, ngononophelo ndenza indlela yam ngaphaya kwesango lokungena elityeni kwikhefu lam lasekhaya, iSan Onofre. Iqaqobana labasenzi lindibethe lada lafika kwinqanaba, apho amaza aqhekeza ekhohlo nasekunene. Ndingena lula emanzini abandayo, ndiyeke ukugodola kutyibilike emqolo njengoko ndizintywilisela kulwelo olunetyuwa. Yincasa erhabaxa elulwimini xa ndikhotha amathontsi emilebeni. Ivakala njengekhaya. Ndiqengqeleka ebhodini yam kwaye ndibheqa ukuya kwixesha lokuphumla, ngelixa emva kwam, isibhakabhaka siqokelelana ngokwamabhanti apinki njengoko ilanga litshona kancinci kwiiNtaba zeSanta Margarita.

Amanzi acwengile kwaye ndiyakwazi ukubona amatye kunye neebhedi ze-kelp ezantsi kwam. Iintlanzi ezimbalwa. Akukho namnye kookrebe ohleli kule mizi yabo. Ndizama ukungahoyi ii-reactors ezizayo ze-San Onofre Nuclear Power Plant elawula unxweme olunesanti. Ezi 'ingono' zimbini, njengoko zibizwa ngolo hlobo ngothando, ngoku zivaliweyo kwaye zikwinkqubo yokuyekiswa ukusebenza, zime njengesikhumbuzo esicacileyo sobungozi bendalo bale ndawo yokusefa.

Kwiinyanga ezimbalwa ezidlulileyo, isigodlo sesilumkiso sikaxakeka sakhala ngokuqhubekayo kangangemizuzu eli-15, kungekho myalezo kawonke-wonke wokuphelisa uloyiko lwabo basemanzini. Ekugqibeleni, sigqibe kwelokuba, yintoni? Ukuba le yayiyingozi yokuqhaqha okanye i-radioactive, sasisele sihamba, ngoko kutheni singasonwabeli nje amaza akusasa. Ekugqibeleni sawufumana umyalezo “wovavanyo”, kodwa sasisele sirhoxa kwilishwa.

Siyazi ukuba ulwandle lusengxakini. Kunzima ukutyhila iphepha ngaphandle kwefoto yenkunkuma, iplastiki, okanye ukuchitheka kweoyile yamva nje egquba amanxweme kunye neziqithi zonke. Ukulambela kwethu amandla, okwenyukliya kunye nalawo avela kumafutha efosili, kudlule kwindawo apho sinokungawuhoyi umonakalo esiwenzayo. "Indawo yokucebisa." Kunzima ukuwaginya loo mazwi njengoko sigxalathelana kumda wenguqu kungekho thuba lokuchacha.

Sithi. Thina bantu. Ngaphandle kobukho bethu, ulwandle beluya kuqhubeka lusebenza njengoko lwalusenza kangangamawaka eminyaka. Ubomi baselwandle babuya kwanda. Imigangatho yolwandle yayinyuka ize iwe. Ikhonkco lendalo lemithombo yokutya beliya kuqhubeka lizixhasa. I-Kelp kunye neekorale ziya kuchuma.

Ulwandle lusikhathalele – ewe, lusikhathalele – ngokuqhubeka kwethu sizisebenzisa ngokumfamekileyo izixhobo zokusebenza kunye neziphumo ebezingalindelekanga ezilandelayo. Ngelixa sivutha ngumsindo ngenxa yamafutha efosili, sinyusa umthamo wekhabhoni kwindawo yethu eethe-ethe neyohlukileyo, ulwandle luthe cwaka lufunxa okugqithisileyo kangangoko kunokwenzeka. Isiphumo? Isiphumo esibi esibi esibizwa ngokuba yi-Ocean Acidification (OA).

Oku kuncipha kwipH yamanzi kwenzeka xa ikharbon diokside, efunxelwe emoyeni, ixuba namanzi olwandle. Itshintsha i-chemistry kwaye inciphisa ubuninzi be-carbon ion, isenza kube nzima ukubala izinto eziphilayo ezifana ne-oyster, i-clams, i-urchins yolwandle, ii-corals zamanzi angekho nzulu, iikorale zolwandle ezinzulu, kunye neplankton ye-calcareous ukwakha nokugcina amaqokobhe. Ukukwazi kweentlanzi ezithile ukubona izilwanyana ezizingelayo kuyancipha kwiasidi eyongeziweyo, nto leyo ebeka yonke iwebhu yokutya emngciphekweni.

Uphononongo lwakutsha nje lufumanise ukuba amanzi asuka eCalifornia enza iasidi kabini ngokukhawuleza kunezinye iindawo emhlabeni, esoyikisa ukuloba okubalulekileyo kunxweme lwethu. Imisinga yolwandle apha ithande ukujikeleza kwakhona amanzi abandayo, aneasidi engaphezulu ukusuka nzulu elwandle ukuya phezulu, inkqubo eyaziwa njengokunyuka. Ngenxa yoko, amanzi aseCalifornia ayesele eneasidi ngakumbi kunezinye iindawo ezininzi zolwandle ngaphambi kwe-OA. Ndijonge phantsi kwi-kelp kunye nentlanzi encinci, andiluboni utshintsho emanzini, kodwa uphando luqhubeka lubonisa ukuba into endingayiboniyo idala umonakalo kubomi baselwandle.

Kule veki, i-NOAA ikhuphe ingxelo ebonisa ukuba i-OA ngoku ichaphazela ngokulinganayo iigobolondo kunye nezitho zengqondo ze-Dungeness Crab. Le crustacean ixabisekileyo lelinye lamashishini okuloba axabisekileyo kuNxweme oluseNtshona, kwaye ukutshatyalaliswa kwayo kuya kudala isiphithiphithi sezemali kushishino. Sele, iifama zeoyster kwiphondo laseWashington, kuye kwafuneka zilungelelanise imbewu yeebhedi zazo ukunqanda ukuxinana okuphezulu kweCO2.

I-OA, exutywe nokunyuka kwamaqondo obushushu olwandle ngenxa yokutshintsha kwemozulu, iphakamisa imibuzo yokwenyani yokuba izinto eziphila elwandle ziya kuphila njani kwixesha elide. Uqoqosho oluninzi luxhomekeke kwintlanzi nakwi-shellfish, kwaye kukho abantu emhlabeni wonke abaxhomekeke kukutya okuvela elwandle njengomthombo oyintloko weprotheyini.

Ndinqwenela ukuba ndingahoya iinyani, kwaye ndenze ngathi olu lwandle luhle kakhulu ndihleli kulo lulungile, kodwa ndiyazi ukuba asiyonyani. Ndiyazi ukuba ngokudibeneyo kufuneka siqokelele izixhobo zethu kunye namandla okucutha ukuthotywa esithe sakusukela. Kuxhomekeke kuthi ukuba sitshintshe imikhwa yethu. Kuxhomekeke kuthi ukuba sifune ukuba abameli bethu kunye norhulumente wethu bajongane nezoyikiso, kwaye bathathe amanyathelo ngomkhamo omkhulu wokwehlisa ukukhutshwa kwekhabhoni yethu kwaye bayeke ukutshabalalisa inkqubo yendalo esixhasa sonke.  

Ndibhexa ukuze ndibambe iliza, ndiphakame, ndize ndijonge ubuso obuqhekekayo. Intle kangangokuba intliziyo yam yenza i-flop-flop encinci. Umphezulu ucacile, ucwengile, ucocekile. Andiyiboni i-OA, kodwa andikwazi ukuyihoya. Akukho namnye kuthi onokukwazi ukwenza ngathi akwenzeki. Alukho olunye ulwandle.
