Izinto ezingaqhelekanga "zokutya zasemanzini" zityhaphaza izazinzulu kwaye zibeka ingozi yokufa kwihlabathi eliphilayo ...
Ngamanye amaxesha imfihlelo yemvelo ibonakala ingaqhelekanga ngaphezu kobukho bobukho bemimoya okanye ukubonakala kwemimoya evela kwezinye ihlabathi. Kwimpuma yasempuma yeUnited States kunye ne-Australia iminyaka engaphezu kweyishumi, abahlali baye bahlangabezana neebhola eziqhelekileyo eziluhlaza olwandle, ukuchazela ukubonakala kwazo kwindlela yokujonga inzululwazi ukuze kungabikho mntu.
Imbali yesiqhelo esingaqhelekanga kummandla wonxweme
Ngo-2002, kwisixeko saseHlton, esise-United States yaseVirginia, abantu bafumene ekuseni kusasa elunxwemeni "izipho" ezilethwa yi-Atlantic Ocean ebusuku. Abazange baxabise isipho sezinto kwaye baphinda baxela kumapolisa. Abasebenzi beSebe baqhagamshelana neengcali zezinto zezilwanyana kunye nezendalo zendalo ezithatha iifoto zithumela kwi-intanethi.
Izinto ezifunyenweyo zisesimo sebhola yombala omnyama omnyama, ubungakanani bhola kwi-tennis okanye kwibalafu. Unxweme apho bafunyanwe khona ubuncinane ubuncinane beemitha ezili-300. Amabhola athatyathwa kwiimvavanyo zebhubhoratri, kwaye iziphumo zazo, ngokuqinisekileyo, zahlulwa.
Mhlawumbi abantu bayakulibala ngeli bali, balibhale kwiimfono zendalo, kodwa sele sele ngo-2014 iibhola ezifanayo ziwela ngenye yamabhishi aseSydney e-Australia. Izazi zezilwanyana zezilwandle kufuneka zibhalise ukufumana kwaye zicele iifologists ngoncedo ekufundeni kwabo.
Izakhiwo ezinqabileyo zeebhola ezihlaza
Isizathu sokuba iibhola zibangele inkxalabo phakathi kwabemi bezidolophu ezimbini e-US nase-Australia. Ukususela kumgama, bafana nesiponji, xa ihlahlela amanzi, iyanda ukuya kubukhulu bebhola lebhola. Kwakunjalo ukufana okwabangela abantu ukuba bavakalise, okwakusisigqibo esingenangqiqo, njengokuba omnye wamafakazi angamaNgqina athi:
"Ummelwane wam, uMaria Segnery, wafumanisa isitya emanzini aphambene nendlu yakhe yaselwandle e-Palm Island waza wamthabatha ibhola elwandle. Xa unyana wakhe wagijimela kuye waza wazama ukumthabatha, kwabonakala ukuba unzima kakhulu ukuba anikezwe elunxwemeni ngumntu oyedwa. "
Ehlabathini okanye kumhlaba, ibhaluni iyancipha kwaye iyancipha kwisayizi yayo yangaphambili. Inomfanekiso ojikeleze ngokugqibeleleyo kwaye ucokola njengelwandle, kodwa ayinanto ephilileyo yolwandle. Kwimeko elomileyo, ibhola lobulukhuni ibonakala njengeglasi okanye isinyithi - kwaye ixabisa ngokuchanekileyo kunokuba ibonakala ngokuqala.
Kutheni iinqabileyo zeebhola eziluhlaza zingenakuchazwa ngabazinzulu?
I-biologist eYunivesithi yaseSydney egama lingu-Ellen Getel uye wafunda ubomi baselwandle iminyaka emininzi, ngoko ke amapolisa amnika ilungelo lokuqala ukubhola ibhola. Njengo-Ellen, kunye nezinye izazinzulu azi ukuba ziphi "iivenka zokutya" zivela:
"Andikwazi ukuqonda ukuba yintoni imvelaphi yale nto - isilwanyana, isityeyamaminerali, okanye enye into. Zibonakala ngathi ukuba zenziwe ngokufanelekileyo. Inokuba yinto yokwenza intambo, kodwa ulwandle alukwazanga ukuwaphula kwaye wenze zonke izinto ezilinganayo. "
Ibhinqa lenzululwazi lisondele ekufumaneni impendulo ngokufanelekileyo kwaye yanquma ukufundisisa iincwadi zezinye i-biologists, kodwa ayifumananga nantoni kuwo malunga neebhola zamanzi. U-Ellen ukwesaba ukuba angalimaza izilwanyana:
"Ukuba le nto iyawa, umzekelo, kwisisu ukuya kumahawulu kwaye iya kuhlanganiswa apho, ezi zilwanyana zasemanzini ziya kutshabalalisa indlala. Emva koko, iimbhozo azikwazi ukugawula iibhola. Baya kuziva ukuba isisu sigcwele, kwaye siyayeka ukutya. Izikhumbiso azinazo, kuba le nto ayifumene neentlanzi. Kodwa intlanzi inokuba yintsipho ngokwaneleyo ukugwinya into engaziwayo. Ukuhamba kwam umphefumlo wokuqala, xa ezi bhola zavela, kwakufuneka zihambe kwaye zisuse ngokukhawuleza zonke ezi zinto zivela kwiindawo eziselwandle. "
U-Ellen wacela icebiso kwi-NASA - kwaye waphendulwa. Ekubeni abasebenzi baseburhulumenteni sele beqhelana neebhola eziluhlaza ezifunyanwe elunxwemeni e-US, bamema isayensi ukuba isebenze kunye, ingafaki inkcazo kwingxelo yokufumanisa. Iindwendwe zikwazi ukufumanisa ukuba emva kokufudukela kwibhubhoratri zonke iibhola ziyahlukana ngokungahambelani ezimbini. Ndiyazibuza ukuba yiziphi izazinzulu ezikwazi ukuzifumana ngaphakathi kwazo?
