Ngexesha le-1998 kunye ne-2002 babenexesha elibi, kodwa kude kube ngo-2016 khange baphinde basokole isiganeko esinje, umahluko wokuba ukusukela ngoko abanalo ixesha lokubuyela kwimeko yesiqhelo.

»Kuthatha ubuncinci ishumi leminyaka ukubuyiswa ngokupheleleyo kweekorale ezikhula ngokukhawuleza, ke Iziganeko zokuphuma kwebala ngobuninzi beenyanga ezili-12 ziqhelile zinika amathuba okufumana kwakhona amatye ezonakaliswe ngo-2016Ucacisile uJames Kerry, isayensi yezaselwandle kwiYunivesithi yaseJames Cook (Australia).
