Izisombululo zilele nje ngasezantsi komphezulu: uSuku lokusiNgqongileyo lweHlabathi ngo-2012

nguMark J. Spalding, uMongameli we-Ocean Foundation

NgoJuni 5 nguSuku lweHlabathi lweNdalo, usuku lokuqinisekisa ukuba impilo yemithombo yendalo kunye nempilo yabantu iyafana. Namhlanje sikhumbula ukuba siyinxalenye yenkqubo enkulu, entsonkothileyo, kodwa engenasiphelo.

Xa u-Abraham Lincoln wonyulwa njengoMongameli, amanqanaba e-carbon dioxide ye-atmospheric abalwa kwiingxenye ze-200-275 kwi-million range. Njengoko uqoqosho lwemizi-mveliso lwalukhula kwaye lukhula emhlabeni wonke, kwaba njalo nangobukho bekharbon diokside emoyeni. Njengerhasi yegreenhouse ekhokelayo (kodwa ingeyiyo yodwa), imilinganiselo yekharbon diokside isinika umyinge wokulinganisa ukusebenza kwethu ekuzinziseni iinkqubo esixhomekeke kuzo. Kwaye namhlanje, kufuneka ndivume iindaba zeveki ephelileyo zokuba ukufundwa kwekharbon diokside kwiatmosfera engaphezulu kweArctic kuye kwafikelela kuma-400 eenxalenye ngesigidi (ppm)—ibenchmark eyasikhumbuza ukuba asenzi kakuhle umsebenzi wobugosa ngendlela ebesifanele ukuyenza.

Nangona ezinye iingcali zikholelwa ukuba akukho ukubuyela umva ngoku sigqithise kwi-350 ppm ye-carbon dioxide emoyeni, apha e-The Ocean Foundation, sichitha ixesha elininzi sicinga kwaye sikhuthaza uluvo ikhabhoni eluhlaza okwesibhakabhaka: Ukubuyisela nokukhusela i-ecosystems yaselwandle kunceda ekuphuculeni amandla olwandle okugcina i-carbon engaphezulu kwi-atmosfera yethu, kwaye iphucula impilo-ntle yeentlobo ezixhomekeke kwezo zinto ziphilayo. Amadlelo engca yolwandle, amahlathi eengrove, kunye nemigxobhozo eselunxwemeni ngamahlakani ethu kuphuhliso loluntu oluzinzileyo. Okukhona sizibuyisela kwaye sizikhusela, kokukhona ziya kuba ngcono kwiilwandle zethu.

Kwiveki ephelileyo, ndifumene ileta emnandi evela kumfazi ogama linguMelissa Sanchez kumazantsi eCalifornia. Ebesibulela (kwintsebenziswano yethu neColumbia Sportswear) ngeenzame zethu zokukhuthaza ukubuyiselwa kwamadlelo engca yolwandle. Njengoko wabhalayo, "Ingca yolwandle yimfuneko ebalulekileyo kwizinto eziphilayo zaselwandle."

UMelissa unyanisile. Ingca yolwandle ibalulekile. Yenye yeendawo zokuhlala elwandle, iphucula ukucaca kwamanzi, ikhusela amanxweme ethu kunye namanxweme ekubhujisweni sisiphango, amadlelo engca yolwandle anceda ukuthintela ukhukuliseko ngokubambisa intlenga kunye nokuzinzisa umgangatho wolwandle, kwaye abonelela ngokuthathwa kwekhabhoni ixesha elide.

Iindaba ezimnandi kwiinxalenye ze-CO2 kwisigidi ngaphambili zivela kwi- uphononongo olukhutshwe kwinyanga ephelileyo olubeka kucace ukuba ingca yolwandle igcina ikhabhoni eninzi kunamahlathi. Enyanisweni, ingca yolwandle ithatha ikhabhoni enyibilikisiweyo emanzini olwandle anokuthi ngenye indlela yongeze kwi-asidi yolwandle. Ngokwenza njalo, kunceda ulwandle, eyona ndawo yethu inkulu ye-carbon sink iqhubeke nokufumana ukukhutshwa kwekhabhoni kwiifektri zethu kunye neemoto.

NgeSeaGrass yethu Khulisa kwaye 100/1000 Iiprojekthi ze-RCA, sibuyisela amadlelo engca yolwandle eyonakaliswe kukumisa izikhephe kunye nezivubeko zeprop, ukukhuthuka kunye nokwakhiwa konxweme, ungcoliseko lwezondlo, kunye nokutshintsha okukhawulezileyo kokusingqongileyo. Ukubuyisela amadlelo kwakhona kubuyisela amandla abo okuthatha ikhabhoni kwaye bayigcine amawaka eminyaka. Kwaye, ngokubamba amanxeba kunye nemiphetho erhabaxa eshiywe kumhlaba wesikhephe kunye nokukhukuliswa senza amadlelo omelele ekuphulukaneni nokhukuliseko.

Sincede sibuyisele ingca yolwandle namhlanje, nge-10 yeedola nganye siya kuqinisekisa ukuba unyawo lwesikweri lwengca yolwandle eyonakeleyo lubuyiselwe empilweni.
