Iziphumo zotshintsho lwemozulu ziyintlekele kumawakawaka eentlobo zezilwanyana nezityalo kwihlabathi liphela. Kule meko, sibuyela umantla mpuma we-Australia ukuya kubona iGreat Barrier Reef ehluphekayo omnye ucoceko olukhulu lonyaka wesibini ngokulandelelana.
Ukuba oku kuyaqhubeka, kuya kwenzeka ntoni kwiingqaqa zekorale?
IGreat Barrier Reef
IGreat Barrier Reef yindawo ehlala izityalo nezinto eziphilayo malunga neekhilomitha ezingama-2.300 XNUMX ubude ezibhengezwe njenge-UNESCO njengeLifa leMveli yeHlabathi. Ukuphuma kwegazi emzimbeni kubangelwa kukwanda kwamaqondo obushushu bamanzi olwandle ngenxa yotshintsho lwemozulu.
Kusekutsha kakhulu ukuba ungazi ukuba iziphumo ezibi zinokuthelekiswa ne-bleaching yonyaka ophelileyo, ithathwa njengeyona imbi kakhulu erekhodiweyo kwiGreat Barrier Reef, apho kwenzeka amatyala afanayo ngo-1998 nango-2002.
Ayisekho imicimbi ukuba ngaba lo msitho umbi okanye ubi kakhulu kunangaphambili, ibalulekile kuphela into yokuba imeko-bume yehlabathi iyatshintsha kwaye izisa iminyhadala egqithisileyo rhoqo kwiGreat Barrier Reef.
Ukufa kwekorale
Utshintsho lwemozulu kulo nyaka uphelileyo lutshabalalise iipesenti ezingama-22 zekorale kuyo yonke indalo. Amakhorali anobudlelwane obukhethekileyo kunye ne-microscopic algae ebizwa ngokuba yi-zooxanthallae, ebonelela ngemikhosi yabo ioksijini kunye nenxalenye yeekhompawundi eziyivelisa ngefotosinthesisi.
Ngotshintsho lwemozulu kunye nokunyuka kwamaqondo obushushu, ezi zixhomekeke kuxinzelelo lwendalo, uninzi lweekorale lukhupha i-zooxanthallae yazo ngobuninzi, kwaye ii-coral polyps zishiywa zingenawo umbala. Njengoko zingenayo i-pigmentation, zibonakala ziphantse zibonakale kumathambo ezilwanyana.
Qho ngonyaka kufa iikorale ngenxa yokutshintsha kwemozulu kwaye ngezinga esiqhubeka ngalo ukungcolisa, amaqondo obushushu eelwandle kunye neelwandle awayi kuyeka ukunyuka.
