Ubushushu behlabathi bubangela izinto ezimangalisayo emhlabeni jikelele njengale siza kuthetha ngayo. Ulwandle lweCaspian lolona mzimba mkhulu wamanzi alulwelo emi ngaphakathi kuwo wonke umntu ehlabathini. Nangona kunjalo, ngenxa yokufudumala kwehlabathi kuhamba kancinci kodwa ngokuthe ngcembe ngumphunga kule minyaka ingamashumi amabini idlulileyo.
Ukwanda kwamaqondo obushushu anxulumene notshintsho lwemozulu kunye nokufudumala komhlaba kubangela ukuba uLwandle lweCaspian luphulukane nomthamo omkhulu wamanzi. Inokuba yintoni imiphumo yoku?
Isifundo kuLwandle lweCaspian
Amanqanaba amanzi kuLwandle lweCaspian yehle phantse ngeesentimitha ezisi-7 ngonyaka ukusuka ku-1996 ukuya ku-2015, okanye phantse i-1,5 yeemitha zizonke, ngokweziphumo zophando olutsha. Inqanaba langoku loLwandle lweCaspian yimitha enye kuphela ngaphezulu kwenqanaba lembali elisezantsi lafikelelwa emva kweminyaka yoo-1.
Oku umphunga wamanzi ovela kuLwandle lweCaspian unxulunyaniswe nobushushu obuphakamileyo kunomoya oqhelekileyo kulwandle. Idatha yesifundo ityhila ukuba amaqondo obushushu oLwandle lweCaspian enyuke ngeqondo elinye phakathi kwamaxesha amabini athathelwa ingqalelo phakathi konyaka we-1979-1995 nowe-1996-2015.
Iziphumo zobushushu bomhlaba
Iziphumo zokunyuka kwamaqondo obushushu okubangelwe kukufudumala komhlaba kubangela ilahleko yomthamo omkhulu weli chibi lamanzi anetyuwa kunye nokwehla kwezinto eziphilayo kulo eziya kubandezeleka njengoko amaqondo obushushu esijikelezi-langa enyuka ngakumbi.
Ulwandle lweCaspian lujikelezwe ziintlanga ezintlanu kwaye luqukethe ubuninzi bendalo kunye nezilwanyana zasendle ezahlukeneyo. Ikwangumthombo obalulekileyo wokuloba kumazwe angqongileyo. Ukuhla kwayo iya kuba neziphumo kwixesha elizayo.
Kuyamangalisa ukubona indlela ubushushu behlabathi obukwaziyo ukukhupha umphunga kwiilwandle eziye zahlala apho kwizigidi zeminyaka kwaye kwiinkulungwane nje ezimbalwa ziyaphela.
