I-Marine Ecosystems

Kulesi sigaba, hlola ukuthi ukudoba kwezimboni kanye nokuxhashazwa ngokungapheli kolwandle kuye kwaphusha kanjani imvelo yasolwandle onqenqemeni lokuwa. Kusukela ekucekeleni phansi kwezindawo zokuhlala kuye ekwehleni ngendlela emangalisayo kwezinhlobo zezilwane, lesi sigaba sidalula izindleko ezifihlekile zokudoba, ukuvuna ngokweqile, kanye nomthelela wazo ofinyelela kude empilweni yasolwandle. Uma ufuna ukuqonda intengo yangempela yokudla kwasolwandle, yilapho ungaqala khona.
Kude nesithombe sothando sokudoba ngokuthula, izilwane zasolwandle zibanjwe ohlelweni olunonya lokuzikhipha. Amanetha ezimbonini awagcini nje ngokubamba izinhlanzi—aphinde abambe futhi abulale izilwane ezingenakubalwa ezingahlosiwe njengamahlengethwa, izimfudu noshaka. Ama-trawler amakhulu kanye nobuchwepheshe obuthuthukisiwe bucekela phansi ulwandle, bucekele phansi izixhobo zamakhorali, futhi buthuntubeze ibhalansi entekenteke yemvelo yasolwandle. Ukudoba okuhlosiwe kwezinhlobo ezithile zezilwane kuphazamisa amaketanga okudla futhi kuthumela imiphumela embi kuyo yonke indawo yasolwandle—nangale kwalokho.
Imvelo yasolwandle iwumgogodla wempilo eMhlabeni. Zikhiqiza umoya-mpilo, zilawula isimo sezulu, futhi zisekela uxhaxha lwezinhlobonhlobo zezinto eziphilayo. Kodwa inqobo nje uma siphatha izilwandle njengezinsiza ezingenamkhawulo, kokubili ikusasa lazo nelethu kuhlala kusengozini. Lesi sigaba simema ukuzindla ngobuhlobo bethu nolwandle nezidalwa zalo—futhi sidinga ukuguqukela ezimisweni zokudla ezivikela ukuphila kunokukuqeda amandla.

Amahlengethwa kanye nemikhomo ihlele ubuntu eminyaka yamakhulu eminyaka, ukuthunjwa kwabo kwezokuzijabulisa nokudla kwakha izingxoxo ezijulile zokuziphatha okuhle. Ukusuka kwimibukiso etholwe emapakini wasolwandle ukuze ukwazi ukusetshenziswa kwabo njengezidlakudla emasikweni athile, ukuxhashazwa kwalezi zilwane ezincelisayo zasolwandle kuphakamisa imibuzo ngenhlala-kahle yezilwane, ukongiwa kanye nesiko. Lo mbhalo uhlola amaqiniso abuhlungu ngemuva kokwenza izinto nokuzingela, okhanyisela imithelela ngokomzimba nangokwengqondo ngenkathi ehlola ukuthi ukuthweswa ngempela kusebenza imfundo noma ukonga

Ngaphansi kwamagagasi, ingozi engabonakali imangalisa ngemvelo yasolwandle-isipoki ukudoba. Amanetha ashiywe kanye nokudoba amagiya athule buthule olwandle, ukudonsa kanye nokubulala izimfudu zasolwandle, amahlengethwa, nemikhomo, nezinye izidalwa zasolwandle ezingenakubalwa. Lokhu kubhujiswa okuqhubekayo akuphelanga nje kuphela ezinhlobonhlobo ezithile kodwa futhi kube nezinhlekelele zonke zemvelo. Njengoba lezi "Ghost amanetha" ziqhubeka nohambo lwazo olubulalayo, zigcizelela isidingo esiphuthumayo sesenzo sokuvikela izilwandle zethu futhi silondoloze izinto eziphilayo. Hlola umthelela omubi wokudoba okuyisipoki futhi ufunde ukuthi imizamo ehlanganisiwe ingasiza kanjani ukuvikela impilo yasolwandle ezizukulwaneni ngezizukulwane ezizayo

Isidingo esikhulayo sokudla kwasolwandle siligqugquzele i-aquaculture embonini echumayo, kepha inhlala-kahle yezinhlanzi ezilimazeke ivame ukuhlala yanda kwande. Ihlanganiswe namathangi agcwele kakhulu ngokucebisa okulinganiselwe, lezi zilwane zibhekene nengcindezi, ukuqubuka kwezifo, kanye nempilo ehlehlisiwe. Lo mbhalo usikhanyisela ngesidingo esicindezelayo sezindinganiso ezingcono ekulimaleni kwezinhlanzi, uqokomisa izinselelo zemikhuba yamanje ngenkathi uhlola ezinye izindlela ezizinzileyo nezokuziphatha. Thola ukuthi izinketho ezinolwazi kanjani neziqondiso ezinamandla ezingasiza ekuguquleni i-waquaculture ibe umzamo onobuhlungu obuningi nomthwalo wemfanelo

Izilwandle, zithatha ngaphezulu kwama-70% omhlaba womhlaba, ziyindlela yokuphila yezinhlobo ezingenakubalwa futhi zidlala indima ebaluleke kakhulu ekulawuleni isimo sezulu seplanethi. Kodwa-ke, imikhuba yokudoba engagcineki icindezela izindondo zasolwandle emikhawulweni yazo. Ukudoba ngokweqile kanye nokulima kwezinhlanzi zezimboni kuyizinto eziphilayo ziyehla, kuphazamise amawebhusayithi okudla okubucayi, kanye nokungcolisa izindawo zokuhlala zibalulekile empilweni ye-Ocean. Njengoba ukufunwa kwasolwandle komhlaba kwasolwandle kukhuphuka, le misebenzi insongela ukuhlukahluka kwezinto eziphilayo kanye nokulingana kwempilo yasolwandle. Ngokwamukela imikhuba yokudoba esimeme kanye nokwamukela ezinye izindlela ezisuselwa ekudleni kwasolwandle, singavikela lezi zinto ezibonakalayo ngenkathi siqinisekisa ukuphepha kokudla. Lo mbhalo uhlola imithelela ekude efinyelela olwandle olwandle lwethu futhi ihlole izixazululo ukuvikela ikusasa labo

Uma kukhulunywa ngokuzitika ngemikhiqizo yasolwandle ewubukhazikhazi njenge-caviar nesobho lika-shark fin, intengo idlulela ngalé kwalokho okuhlangabezana nokunambitha. Eqinisweni, ukudla lezi zibiliboco kuza nesethi yezimiso zokuziphatha ezingenakuzitshwa. Kusukela kumthelela wemvelo kuya onyameni lokukhiqizwa kwazo, imiphumela emibi ifinyelela kude. Lokhu okuthunyelwe kuhlose ukuhlolisisa izimiso zokuziphatha eziphathelene nokusetshenziswa kwemikhiqizo yasolwandle ewubukhazikhazi, kukhanyiselwe ngesidingo sezinye izindlela ezisimeme kanye nokukhetha okufanele. Umthelela Wezemvelo Wokudla Imikhiqizo Yasolwandle Ewubukhazikhazi Ukudoba ngokweqile kanye nokucekelwa phansi kwemvelo okubangelwa ukusetshenziswa kwemikhiqizo yasolwandle ewubukhazikhazi njenge-caviar nesobho lika-shark fin kunemithelela enzima yemvelo. Ngenxa yesidingo esikhulu salezi zinto zokudla zasolwandle eziwubukhazikhazi, izinhlanzi ezithile kanye nemvelo yasolwandle kusengcupheni yokuwa. Ukusetshenziswa kwemikhiqizo yasolwandle ewubukhazikhazi kunomthelela ekuncipheni kwezinhlobo zezilwane ezisengozini futhi kuphazamisa izinto ezithambile…

Njengabantu ngabanye, sidlala indima ebalulekile ekulolongeni ikusasa leplanethi yethu ngezinqumo esizenzayo - futhi lokho kuhlanganisa nokudla esikudlayo. Eminyakeni yamuva nje, kuye kwaba nokuqwashisa okwandayo mayelana nomthelela wemvelo wezinketho zethu zokudla. Kusukela ku-carbon footprint yokukhiqizwa kokudla kuye emiphumeleni yokugawulwa kwamahlathi kanye nokulima kwezimboni, ukukhetha kwethu ukudla kunemithelela efinyelela kude empilweni yeplanethi yethu. Kulokhu okuthunyelwe kwebhulogi, sizohlola izindlela ezahlukahlukene lapho ukukhetha kwethu ukudla okungaba nomthelela kwezemvelo futhi sixoxe ngezixazululo ezisimeme zokunciphisa le miphumela. Ngokuqonda ukuhlobana phakathi kokukhetha kwethu ukudla nendawo ezungezile, singenza izinqumo ezinolwazi oluningi ezifaka isandla kumhlaba oluhlaza futhi ozinzile. I-Carbon Footprint yokukhiqizwa Kwethu Kokudla Kokudla inegalelo elikhulu ekukhishweni kwesisi esibamba ukushisa kanye nokushintsha kwesimo sezulu. Yonke inqubo yokukhiqiza, ukuthutha, kanye…
