Iintlobo ngeentlobo zeminenga
Kukho iintlobo ezininzi zeminenga kwiilwandle zehlabathi, nganye inemilinganiselo eyahlukileyo exhomekeke kwiintlobo zayo kunye neminyaka. I Umnenga oluhlaza, ngokomzekelo, saziwa njengesona silwanyana sikhulu kwezakha zakho kwisijikelezi-langa sethu, sikhulu ngakumbi kunezona dinosaur zikhulu. Ezi zigebenga zinokufikelela kubude obuziimitha ezingama-33 kunye nobunzima beetoni ezili-190.
Ezinye izigebenga zaselwandle ezifana I-Humpback Whale okanye Umnenga ongwevu Ziyakwazi ukufikelela kubude ukuya kwi-15 kunye ne-18 yeemitha ngokulandelelanayo. Nangona kunjalo, asiyiyo yonke iminenga emikhulu kakhulu, kukho into ebizwa ngokuba yi iminenga encinci njenge pilot whale elilinganisa malunga neemitha ezi-6 ubude.
Siwulinganisa njani umnenga?
Uninzi lwemilinganiselo yeminenga iqhutywa ngeendlela ezingahlaseliyo ezihlonela kwaye zigcine ubomi kunye nentlalontle yezi zidalwa. Ezona ndlela zixhaphakileyo ziquka ukusetyenziswa kweefoto zasemoyeni, iidrones, kunye nemilinganiselo yelaser echanekileyo.
Ngokusebenzisa iindlela ezifana ukufota emoyeni okanye Drones, abaphandi banokulinganisa umnenga ngaphandle kokusondela kakhulu. Ezi ntlobo zeendlela zikuvumela ukuba uthathe imilinganiselo echanekileyo yobude besilwanyana, kunye nombono oqhelekileyo wobukhulu kunye nemeko.
Ungakhula kangakanani uMnenga?
Ukukhula komnenga yinkqubo ebangel’ umdla nechukumisayo. Ngokomzekelo, iminenga eluhlaza inokukhula ukuya kutsho kwiisentimitha ezi-3 ngosuku kwiminyaka yokuqala yobomi babo. Kodwa unokukhula ube mkhulu kangakanani umnenga?
- Umnenga oluhlaza unokufikelela kubude obuphezulu ukuya kuthi ga kwi-33 yeemitha.
- Umnenga ongwevu unokufikelela kwi-18 leemitha.
- Umnenga we-humpback unokukhula ube ziimitha ezili-15 ubude.
Kubalulekile ukuqaphela ukuba iminenga zizidalwa ezikhula ngokucothayo kwaye inokuthabatha phakathi kweminyaka emi-5 ukuya kweli-10 ukuba ifikelele kubungakanani bayo obupheleleyo.
Ukubaluleka kobungakanani boMnenga
Ubukhulu bomnenga ayisosilinganisi nje esibangel’ umdla. Ikwadlala indima ebalulekileyo ekuphileni kweentlobo kunye nokulingana kwe-ecosystem yolwandle. Iminenga, ngenxa yobukhulu bayo kunye nesantya, inokuhamba imigama emide kwaye ibalulekile ekusasazeni izondlo elwandle.
Ngaphezu koko, iminenga ingamaxhoba ezilwanyana ezimbalwa kakhulu. Oku kubangelwa ubukhulu becala kubukhulu bazo, obusebenza njengokhuselo lwendalo kumarhamncwa.
Isigebenga esimangalisayo: Ukukhumbula iWhales
Iminenga, ngobukhulu bayo obukhulu nobungangamsha, ibiluphawu lokunconywa nokuhlonelwa ukutyhubela iminyaka. Ziye zaba ngumxholo weentsomi kunye neentsomi, kwaye ziye zabamba iingcamango zezazinzulu, izazi zendalo kunye nabathandi bezilwanyana ngokufanayo.
Kungumsebenzi wethu njengabemi besi sijikelezi-langa ukukhathalela nokukhusela ezi zinto zimangalisayo zendalo, siqinisekisa ukusinda kwazo kwizizukulwana ezizayo. Ngapha koko, ulwandle belungayi kufana ngaphandle kobukho bezi zigebenga zimangalisayo.
Okokugqibela, ubukhulu bezi zidalwa kwihlabathi lendalo abunakulinganiswa kuphela ngeemitha neetoni, kodwa nakwimpembelelo yazo nokubaluleka kwazo kwi-ecosystem yaselwandle kunye ne-biodiversity yehlabathi.
