Izixazululo Zitholakala Ngaphansi Komhlaba: Usuku Lomhlaba Lwezemvelo lwango-2012

nguMark J. Spalding, uMongameli we-The Ocean Foundation

Umhla zi-5 kuNhlangulana wuSuku Lwezemvelo Lomhlaba, usuku lokuqinisekisa ukuthi impilo yemithombo yemvelo kanye nempilo yabantu kuyefana. Namuhla siyakhumbula ukuthi siyingxenye yohlelo olukhulu, oluyinkimbinkimbi, kodwa olungapheli.

Lapho u-Abraham Lincoln ekhethwa njengoMongameli, amazinga e-carbon dioxide asemkhathini abalwa ezingxenyeni ezingu-200-275 ububanzi besigidi. Njengoba umnotho wezimboni ukhula futhi ukhula emhlabeni wonke, kwaba kanjalo nokuba khona kwesikhutha emkhathini. Njengegesi ebamba ukushisa eholayo (kodwa okungeyona yodwa), izilinganiso ze-carbon dioxide zisinikeza umugqa wokukala ukusebenza kwethu ekusekeleni izinhlelo esithembele kuzo. Futhi namuhla, kufanele ngivume izindaba zangesonto eledlule zokuthi ukufundwa kwe-carbon dioxide emkhathini ngaphezu kwe-Arctic sekufinyelele izingxenye ezingama-400 ngesigidi (ppm)—isilinganiso esisikhumbuza ukuthi asenzi umsebenzi omuhle wobuphathi ngendlela okufanele siwenze.

Naphezu kweqiniso lokuthi abanye ochwepheshe bakholelwa ukuthi akusekho ukuhlehla manje njengoba sesidlule ku-350 ppm we-carbon dioxide emkhathini, lapha e-The Ocean Foundation, sichitha isikhathi esiningi sicabanga futhi sikhuthaza umbono wokuthi ikhabhoni eluhlaza okwesibhakabhaka: Ukuthi ukubuyisela nokuvikela imvelo yasolwandle kusiza ukuthuthukisa amandla olwandle okugcina ikhabhoni eningi emkhathini wethu, futhi kuthuthukisa inhlalakahle yezinhlobo ezincike kulawo ma-ecosystem. Izimfunda zasolwandle, amahlathi omhlume, namaxhaphozi asogwini zingabambisene bethu ekuthuthukisweni komphakathi okusimeme. Lapho sizibuyisela futhi sizivikela kakhulu, izilwandle zethu zizoba ngcono.

Ngesonto eledlule, ngithole incwadi emnandi evela kowesifazane ogama lakhe linguMelissa Sanchez eningizimu yeCalifornia. Ubesibonga (ekubambisaneni kwethu ne-Columbia Sportswear) ngemizamo yethu yokugqugquzela ukubuyiselwa kwezimfunda zasolwandle. Njengoba abhala, “Utshani basolwandle buyisidingo esibalulekile sezinto eziphilayo zasolwandle.”

UMelissa uqinisile. I-Seagrass ibalulekile. Ingenye yezindawo zolwandle, ithuthukisa ukucaca kwamanzi, ivikela ugu namabhishi ethu ekuhlaseleni kweziphepho, izimfunda zasolwandle zisiza ukuvimbela ukuguguleka ngokubamba inzika nokusimamisa ulwandle, futhi zihlinzeka ngokuthathwa kwekhabhoni isikhathi eside.

Izindaba ezinhle ezingxenyeni ze-CO2 ngesigidi ngaphambili zivela ku-a ucwaningo olukhishwe ngenyanga edlule olubeka ngokusobala ukuthi utshani basolwandle bugcina ikhabhoni eningi kunamahlathi. Eqinisweni, utshani basolwandle bukhipha ikhabhoni encibilikisiwe emanzini asolwandle obungafaka i-acidification yolwandle. Ngokwenza kanjalo, kusiza ulwandle, usinki wethu omkhulu wekhabhoni uqhubeke nokuthola ukukhishwa kwekhabhoni ezimbonini nasezimotweni zethu.

Nge-SeaGrass yethu ikhule futhi 100/1000 Amaphrojekthi e-RCA, sibuyisela izimfunda zotshani basolwandle ezilinyazwe isisekelo sezikebhe nezibazi ze-prop, ukugwetshwa nokwakhiwa kogu, ukungcoliswa kwezakhi, kanye nokushintsha kwemvelo okusheshayo. Ukubuyisela izimfunda kuphinde kubuyisele ikhono lazo lokuthatha ikhabhoni nokuyigcina izinkulungwane zeminyaka. Futhi, ngokupheca izibazi namaphethelo amaholoholo ashiywe yizikebhe kanye nokugwazwa senza izimfunda zikwazi ukumelana nokuguguleka.

Sisize sibuyisele utshani basolwandle namuhla, ngo-$10 njalo sizoqinisekisa ukuthi utshani basolwandle obonakele bubuyiselwe empilweni.
