Ezantsi kuvela kwiintaka zamanzi ezifana namarhanisi kunye namadada, kwaye eyona miba iphambili emisela umgangatho wayo ngumjikelo wokutya kunye nokukhula kwemekobume yeentaka zasemanzini. Okukhona umjikelo wokutyisa wamarhanisi namadada umde, kokukhona eqola amarhanisi namadada, kokukhona esiba makhulu ezantsi, kwaye kokukhona ekhula ubukhulu; ukuhla kwamarhanisi kunye namadada emanzini anombala omhle kunye nokucoceka okuphezulu; kumarhanisi kunye namadada akhula kwiindawo ezibandayo, ukuze aqhelane nemekobume ekhulayo, ukuhla kukhulu. Kwaye ixinene, isivuno siphezulu.
Ke ngoko, ukuze siqinisekise ukuba sibonelela abathengi ngeemveliso ezikumgangatho ophezulu ezantsi, sijonge eyona ndawo ifanelekileyo yokukhula kwerhanisi, idada kunye neentaka zamanzi kwihlabathi jikelele ukukhetha abavelisi abakumgangatho ophezulu. Siyakhathalela kwaye siyawuxhasa umgaqo-nkqubo wokukhusela izilwanyana kwinkqubo yokuqokelela phantsi. Zonke iimveliso ezisezantsi zezatifikethi ezilandelekayo emhlabeni jikelele, akukho zilwanyana ziya kwenzakaliswa kwaye zixhatshazwe ngexesha lemveliso kunye nokusetyenzwa kwezantsi. Emva kweminyaka yovavanyo olungqongqo kunye nokungena kwababoneleli abaphantsi, siye saseka ubudlelwane bentsebenziswano bexesha elide nabanye abavelisi abaphantsi. Amanqaku okuqokelela aphantsi abekwe ePoland, eHungary, eRashiya, eIceland, eJamani naseChina.
