Ngelishwa, Namhlanje akukho lwazi luthandwayo malunga nayo yonke into ejikeleza kutshintsho lwemozulu kunye nokufudumala kwehlabathi. Abantu abaninzi bayathandabuza ukucinga ngeziphumo ezibi ezibangelwa lutshintsho lwemozulu kwilizwe lonke.
Emva koko ndiza kukuxelela Iinyaniso ezi-5 malunga nokufudumala kwehlabathi ukuze uqonde ukuba nzulu kangakanani kwaye kubaluleke kangakanani ukufuna izisombululo ngeyona ndlela ingxamisekileyo.
- Ukusukela ngo-1880 ubushushu obujikeleze umhlaba buye benyuka phantse ngeqondo elinye. Kuyamangalisa ukuba kwisithuba esifutshane sexesha, iqondo lobushushu lenyuke kakhulu. Eyona nto imbi kakhulu kukuba uqikelelo aluthembisi konke konke kwaye luthetha ukuba ukwanda kunokuba kukhulu.
- Amanqanaba olwandle anyukile kule minyaka idlulileyo ngenxa yokunyibilika kwezibonda zombini kunye neqabana lomkhenkce. Olu konyuka luneesentimitha ezisi-8 kule minyaka ingama-20 idlulileyo kwaye iingcali ziqikelela ukuba ukuphela kwenkulungwane, inqanaba ngokwalo liya kube lenyuke ngemitha enye.
- Ixesha liya libaxeka kwaye kukuba ubusika buya bubanda kwaye ihlobo liyatshisa. Le nyaniso iya kukhula ngakumbi nangaphezulu kwiminyaka.

Ndiyathemba ukuba ezi nyani zi-5 malunga nokufudumala kwehlabathi zikunceda ukuba uqaphele ukuba kubaluleke kangakanani ukukhathalela umhlaba ngokusemandleni.
