Ulwandle njengoMfelandawonye kwizisombululo zeMozulu: Izinto eziphambili ezithathwa kwiPhulo lethu le-#RememberTheOcean

Kwezi nyanga zimbalwa zidlulileyo, siye sandisa indlela ulwandle olubonelela ngayo ezinye izisombululo ezizezona zokujongana nokutshintsha kwemozulu — ngeli lixa ikwabonelela ngamathuba okuguqula uqoqosho lwethu. 

Nangona kunjalo, ukuze la mathuba aphunyezwe, sifuna ulwandle olusempilweni. Yona is kunokwenzeka ukubuyisela impilo yolwandle ngokunciphisa izenzo zoshishino eziyingozi ngaphandle kokubeka emngciphekweni iindlela zokuphila.

Kwimeko yokuba uyiphosile, sibuyisela awona manqaku abalulekileyo kwiphulo lethu leendaba zosasazo ezingezantsi kunye namanye amaqabane ethu asinceda #RememberTheOcean kunye nezibonelelo zayo kwimpilo yethu - kwaye ekugqibeleni, ukusinda kwethu.

Ulwandle lugubungela i-71% yomphezulu womhlaba. Kodwa yenye yezona ndawo zincinci zotyalo-mali. 

Ukuba ulwandle belilizwe, beluya kumela uqoqosho lwesixhenxe ngobukhulu emhlabeni. Nangona kunjalo, ulondolozo lwaselwandle kunye nenzululwazi ibe yenye yezona ndawo zingatyalwanga kakhulu ekugxilwe kuzo kwihlabathi. I-97% yamanzi oMhlaba anikezelwa elwandle. Kodwa ulwandle lubalelwa kuphela malunga ne-7% ye-philanthropy epheleleyo yokusingqongileyo e-US Eli linani elincinane kakhulu. Ingakumbi xa iindawo ezikufutshane nolwandle zisesichengeni kakhulu kwiziphumo zokutshintsha kwemozulu yethu.

Ulwandle ngumdlali obalulekileyo ekulawuleni utshintsho lwemozulu.

Ikhabhoni eluhlaza okwesibhakabhaka yiCO2 ebanjwe yaze yagcinwa ngohlobo lwe biomass kunye nentlenga lulwandle kunye ne ecosystems. Oku kuquka imingxunya, imigxobhozo yetyuwa, namadlelo engca yolwandle. Ikhabhoni eluhlaza yeyona ndlela isebenzayo yokuhluthwa kwekhabhoni yexesha elide kunye nokugcinwa kwayo. 

IMangrove iyodwa igcina malunga ne-CO10 ephindwe kayi-2 kunamahlathi asemhlabeni. Benza ngaphantsi kwe-2% yeendawo zaselwandle, kodwa i-akhawunti ye-10-15% yokungcwatywa kwekhabhoni. Njengoko i-mangrove ikhula, ithatha i-CO2 kwaye iyisebenzise njengeebhloko zokwakha amagqabi, iingcambu kunye namasebe. Nje ukuba amagqabi kunye neemangrove ezindala zifile, ziwela phantsi elwandle kwaye zithathe ikhabhoni egciniweyo kunye nazo. Ihektare enye yehlathi le-mangrove inokugcina malunga ne-1,450 yeeponti zekhabhoni ngonyaka. Oku kuphantse ukuba yimali efanayo ekhutshwe yimoto eqhuba ngaphesheya kwe-US nasemva.

Ulwandle lwethu kunye nemozulu zinxulunyaniswa ngokungenakwahlulwa.

Ulwandle sisinki yekhabhoni enkulu, esikhusela kolona tshintsho lwemozulu lubi. Ikwanciphisa imozulu egqithisileyo, ivelisa ioksijini esiyiphefumlayo, kwaye ivelisa ukutya okuninzi esikutyayo. Kwaye sesona sisombululo sethu sikhulu Ukubanjwa kunye nokugcinwa kwekhabhoni esekwe kwindalo. Enyanisweni, ulwandle lufunxa malunga ne-30% ye-CO2 ekhutshwe ukususela ekuqaleni kwenguqu yezoshishino.  

Ulwandle lukwathwele ubunzima bokutshintsha kwemozulu, kwaye sele lufumana iimpembelelo zalo ezibalulekileyo.

Ngaphezulu kwe-90% yobushushu obugqithisileyo obuvela kwiigesi zegreenhouse bufunxwe lulwandle, nto leyo ekhokelela ekutshintsheni kwamaqondo obushushu, imo yezulu, kunye namaqondo olwandle. Njengoko ulwandle lwethu lufudumala, lukwaphazamisa ukufuduka kwezitokhwe eziphambili zeentlanzi kwaye kubeka emngciphekweni ukuthembeka kokusebenza kwezinto eziphilayo. 

Ukunyuka kwe-CO2 ye-atmospheric kukhokelela kwindawo ene-acidic yolwandle, okanye acidification ulwandle, echaphazela iinkqubo zomzimba kwiintlobo ezininzi zaselwandle. Xa ulwandle lufunxa ngakumbi i-CO2, izinga le-oksijini emanzini liyancipha kwaye alifaneleki kwiintlanzi ezininzi, ngakumbi i-sharks kunye ne-tuna.

Iingqaqa zekorale zibonelela ngokutya kunye nekhusi kwi-25% yazo zonke iintlanzi kunye nokuphila kwizigidi zabantu. Kodwa, ukufudumala kwamaqondo obushushu olwandle kubangela i-coral bleaching kunye nezifo ezosulelayo. Ukwenziwa kweasidi yolwandle kunciphisa ukukhula kwekorale, kwaye ukunyuka komgangatho wolwandle kunokuba negalelo ekwandeni kwentlenga kwiingqaqa zekorale, kuzikrwitsha zife. Izaqhwithi ezinamandla nezixhaphakileyo zinokuzitshayela iikorale, kwaye utshintsho kwimisinga yolwandle luphazamisa ulungelelwaniso lwendalo lwendalo.

Iindaba ezimnandi zezokuba eyona nkqubo ibalulekileyo ye-ikhosistim inokuchacha ukuba sinikezela ngeemeko ezisempilweni. 

Indalo ibisoloko inesona sisombululo, umjikelo wekhabhoni. Ukubanjwa kwekhabhoni esekwe kwindalo kuthetha ukubuyisela imimango kunye nezinye izinto eziphilayo eziselunxwemeni naselwandle, ezolimo ezihlaziya, kunye nokutshalwa kwamahlathi ukususa nokugcina i-CO2 kwizityalo nakwimihlaba. Ezi zicwangciso ezisekelwe kwindalo azigcini nje ukunciphisa ukungabikho kokusesikweni kokusingqongileyo kunye noqoqosho, kodwa zinika ukugcinwa kwekhabhoni ixesha elide njengenzuzo yehlabathi. Ngenxa yoko, kufuneka sikhusele ulwandle. Kwaye kufuneka sikwenze oko kwakamsinya, kuba ezi ndawo zokuhlala zibalulekile kubomi bethu bexesha elide eMhlabeni. 

Iziqithi ezisemhlabeni eziyi-175,000 zihlala abantu abangaphezu kwezigidi ezingama-600.. Ezi ziqithi zisengozini kakhulu kwimingeni yehlabathi esijongene nayo.

Ukutshintsha iipatheni zemozulu, ukunyuka komphakamo wolwandle, ukufudumeza ulwandle, kunye nokusela kakhulu, zonke iindawo ezihlala esiqithini zibetha ngamandla. Kwaye utshintsho kwimekobume yaselwandle lutshabalalisa ushishino lokuloba kwaye luthomalalisa inkqubo yendalo esiphila kuyo uninzi lweziqithi ezixhomekeke kuyo. Amazwe asakhasayo eziqithi ezincinci, njengeBahamas, Haiti, okanye iFiji, enza i-2/3 yamazwe afumana ilahleko ephezulu kakhulu kwiintlekele zendalo.

Iziqithi zibonelela ngamakhaya kunye nendlela yokuphila kubemi bazo. Zikwaxhasa ezona nkqubo zendalo zikhethekileyo nezizimeleyo kwaye zinika ingxelo kuninzi lweshishini lethu lehlabathi lokhenketho. Imigaqo-nkqubo yolwazi lweSiqithi inokunceda ukunciphisa iimpembelelo ezingalunganga zentlalo-qoqosho kunye nemingeni yokusingqongileyo, kunye nokugcina iindawo zokuhamba kunye namakhaya ezigidi zabantu. 

Ulwandle luqhuba iinkqubo zehlabathi ezenza umhlaba kuhlale kuwo abantu.

Bangaphezu kwe-3 yeebhiliyoni zabantu abaxhomekeke kwizinto eziphilayo zaselwandle naselunxwemeni ukuze baziphilise. Ngaphandle kolwandle olusempilweni, ayilulo olo luntu kuphela olusengozini, kodwa bunjalo nobukho bethu bonke.

Ulwandle lwethu lusinika okuninzi. Luxanduva lwethu ukukhathalela ulwandle njengoko lusikhathalele.

Ngabaxhasi bethu kunye namaqabane ethu, sinokufumana izisombululo zehlabathi malunga nokutshintsha kwemozulu.
