Sonke siyazi ukuba ubomi eMhlabeni buvela phantsi kwe-Ocean World, ehlala kuma-70% womhlaba wonke. Ukubunjwa kwehlabathi kubandakanya indawo emininzi yamanzi: i-Atlantic, Pacific, i-Arctic ne-Indian.
Namhlanje ulwandle ludlala indima ebalulekileyo ebomini ngamnye wethu. Ngokunceda, imozulu yomhlaba ilawulwa. Amanzi oLwandle lweHlabathi afumana i-carbon dioxide kwaye asinike i-oksijini. Unyaka wonke ulwandle londla abantu abaninzi emhlabeni kwaye lubapha amayeza afanelekileyo. Lihlala nenani elikhulu lezinto eziphilayo eziphilayo. Kwaye ukuba sifuna ukuqinisekisa impilo ephilileyo thina nakwimbewu yethu, kubaluleke kakhulu ukunyamekela ulwandle kunye nokunyamekela. Enyanisweni, xa sizama ukulondoloza impilo yezilwandle zehlabathi, sicinga ngekamva lehlabathi lethu lonke.
Kukho inzululwazi ekhethekileyo - i-oceanology-eyenziwa ekufundweni kwe-Ocean World. Ukungenelela ekujuleni kolwandle, izazinzulu zifumanisa iindlela ezintsha zokuphila kolwandle kunye nezilwanyana. Ezi zinto zifunyanwa kakhulu kubantu bonke.
Liliphi usuku loMhlaba weeLwandle?
Ekupheleni kuka-1992, kwiinkomfa zehlabathi ezibizwa ngokuthi "iPlanethi yomhlaba", eyayibanjelwe eBrazil, kwacetyiswa ukuba kusekwe iholide entsha - Usuku lweMihlaba yehlabathi, oluguqulelwe kwisiNgesi yiNhlaba yeeLwandle lwasemini kwaye lugubha minyaka yonke ngoJuni 8. Ukususela ngoko, eli holide libhiyozelwa ngabo bonke, ngendlela enye okanye enye, ababandakanyeka kwiingxaki ze-Ocean World. Ekuqaleni le holide yayingabalulekanga. Kwaye ukususela ngo-2009, iMini yeeNxweme zeHlabathi iyabonwa yi-UN General Assembly njengeholide. Namhlanje, i-124 isayine ummiselo wokubhiyozela uMhla woLwandle oMhlaba.
Namhlanje, i-ichthyologists kunye nezendalo, abasebenzi base-aquariums, i- dolphinariums kunye ne- zoos bafuna ukudibanisa yonke imizamo yokukhusela amalungelo olwandle, kwakunye nokulwa nokuhlanzeka kwendalo kunye nolwandle.
Usuku lweMihlaba yamaLwandle lunentsingiselo yendalo. Ngosizo lwalo holide, abasunguli bayo bafuna ukuqwalasela uluntu jikelele kuluntu kwi-World Ocean kunye nokulondolozwa kwabemi balo. Emva koko, ulwandle luyinkqubo ekhethekileyo yendalo exhasa ukulinganisela kwezinto eziphilayo. Kodwa ukungenelela koluntu kuye kwabangela ukuba oku kulandelelaniswa rhoqo: unyaka ngamnye kwi-World Ocean, malunga neenkulungwane zezilwanyana zokuphila olwandle.
Sonke siyazi ukuba namhlanje ingxaki yokungcola kwemoya kunye negesi yokutshisa i-greenhouse iyanzima kakhulu. Ukongezelela, ubuninzi kunye nomgangatho wamanzi okusela eMhlabeni kuhla. Ukugqitywa kwezilwandle kunye nolwandle, ukutshabalaliswa okungalawulwayo kwemithombo yolwandle, ngokukhokelela kukukhokelela ekutshatyalaliswa kwendalo yonke yolwandle. Iingcali zenzululwazi ziqikelela ukuba ngo-2015 u-acidity lwamanzi ase-oceanic unokunyuka ngama-150%, okuya kubangela ukufa kwaphela phantse ubomi bonke baselwandle.
Kunyaka ngamnye ngo-Juni 8, emhlabeni wonke, izinto ezininzi ezahlukeneyo zendalo zenziwe, ngoxa uncedo lwabo abaququzeleli bazama ukuthumela kubo bonke abantu imfuno yokukhusela iNxweme yehlabathi. Kulo suku, imibukiso eyahlukeneyo, imikhosi, iisemina, iintlanganiso zeentlanganiso, iingxoxo zengqikithi yolwandle zigcinwe.
Unyaka wonke, ukubhiyozelwa kweSuku lweeNxweme zeHlabathi kuqhutywa phantsi kwee-mottos ezahlukahlukeneyo. Ngokomzekelo, ngo-2015 bekuzwakala ngathi "Ulwandle oluphilileyo, iplanethi enempilo".
Ngaloo ndlela, ukubhiyozela uMhla woLwandle lweHlabathi, uluntu lunethuba lokulondoloza imvelo, ulwandle kunye nezilwanyana. Kwaye ukukhathazeka okunjalo kubemi be-Ocean World kuyakukhusela ukupheliswa kwezilwanyana ezininzi kunye nezityalo, eziya kubachaphazela ngokuqinisekileyo ubomi bethu ngokukhawuleza.
