Kungani inani lamabhere e-polar liyancipha: yiziphi izizathu

Kungani inani lamabhere amhlophe lincipha? Kusukela ngo-2008, lesi silwane sifakwe eNcwadini Ebomvu. Kodwa ngemva kwakho konke, ibhere elimhlophe liyisilwane esiyingozi, abantu abambalwa abangaqhudelana naso. Siyini isizathu sokuncipha okukhulu kangaka kwenani labantu bakhona?

Kungani inani labantu lincipha amabhere ase-polar: yiziphi izizathu

Ngakho-ke, yiziphi izizathu zalesi simo?

• Isizathu esiyinhloko esenza ukuba inani lamabhere amhlophe linciphe ukukhukhuleka kweqhwa nokuncibilika kwawo. Ngokwezibalo, emashumini ambalwa eminyaka adlule, indawo yeqhwa yehle ngamakhilomitha-skwele ayizigidi ezimbalwa. Phakathi naleso sikhathi, amabhere amhlophe avame ukuhlala eqhweni! Kodwa ezinsikazi zizalela ogwini emihumeni. Futhi ukufika kubo kuya kuba nzima nakakhulu - iqhwa livame ukuphuka futhi likhukhula, lilokhu likhukhuleka liqhubeke liqhela ezweni. Ngaphezu kwalokho, adilika kalula, futhi izilwane kufanele zibhukude amabanga amade. Naphezu kweqiniso lokuthi amabhere e-polar ayizilwane eziqinile impela, kungaba nzima kakhulu kuwo ukubhukuda amabanga amade kakhulu. Ikakhulukazi amazinyane ebhere. Akubona bonke abantu ababhekana nomsebenzi onjalo. Ngaphezu kwalokho, ungakhohlwa ukuthi kukhona ukudla okuncane kakhulu emanzini ajulile.
• Uma sikhuluma ngamanzi, izinga lawo ngokuvamile lishiya okuningi okufanele lifiswe kamuva nje. Njengoba uwoyela ukhiqizwa ngenkuthalo, ngokufanelekile, uvame ukuthuthwa. Futhi ngesikhathi sokuthutha, ngezinye izikhathi izingozi ezihlukahlukene zenzeka, ngenxa yalokho amafutha achitheka emanzini. Wonke amafilimu enziwe mayelana nokuthi uwoyela onjani emanzini - izingozi ezinjalo ziholela ngempela emiphumeleni esabekayo. Ifilimu yamafutha, naphezu kokuthi incane, iholela ekubhujisweni kokubili kwezinhlanzi nezinye izilwane zasolwandle. Kodwa lokhu ukudla kwamabhere! Ngaphezu kwalokho, amafutha angena eboyeni bebhere aholela eqinisweni lokuthi izilwane ziqala ukuba yiqhwa - izici zoboya zokuvikela ukushisa ziyalahleka. Amafutha achithekile ngisho nasenqoleni eyodwa, ngeshwa, angaholela emiphumeleni esabekayo.. Kubandakanya ukufa ngenxa yendlala nokubanda kwamabhere amhlophe.
• Ngena emanzini nakwezinye izinto eziyingozi. Lokhu kubhekisela ezinsimbi ezisindayo, ama-radionuclides, amafutha kanye nezinto zokugcoba, izibulala-zinambuzane. Njengoba izifundo zibonisa, zithinta kabi isimo sohlelo lwe-endocrine kanye nokungavikeleki kwamabhere. Futhi-ke, zonke lezi zinto zibhubhisa ukudla kwamabhere.
• Yiqiniso, abazingeli abangekho emthethweni bayingozi kakhulu emphakathini wamabhere asezintabeni. Naphezu kweqiniso lokuthi ukuvinjelwa kokuzingela lezi zilwane kwaqala ukusebenza kusukela ngo-1956, akukho lutho oluvimba labo abafuna ukuthola isikhumba sabo esiyigugu kakhulu.
• Lesi sici akuvamisile ukuthi kukhulunywe ngaso, kodwa kusadingeka kukhulunywe ngaso. Sikhuluma ngezinhlobo zokuxuba: ezifundeni ezibonakala ngokuhlangana kwezindawo zokuhlala zamabhere amhlophe namabhere ansundu, ziyazalana. Inzalo evela eziphambanweni ezinjalo ibizwa ngokuthi "grolar", "pizzly". Futhi, kubonakala sengathi, yini engalungile ngalokho? Phela amabhere ayazala, izakhi zofuzo ziyathelelana kuhlanganisa nezabamhlophe. Kodwa-ke, ngokungafani nozakwabo abansundu, abakwazi ukuzivumelanisa nezimo, amabhere amhlophe awakwazi ukuguquguquka ngokuphelele kwendalo. Abakwazi nje ukusinda e-tundra, ogwadule noma ezintabeni.

Kungani kunzima ukuthola amabhere amhlophe

Kungani kunzima ukugcwalisa amabhere amhlophe?

• Okokuqala, kufanele kuqashelwe ukuthi amabhere ase-polar awazona izilwane zomphakathi. Bajwayele ukuhlala bodwa kakhulu. Futhi omunye, yiqiniso, kunzima kakhulu ukuthola ukudla, ukubhekana nobunzima. Naphezu kweqiniso lokuthi ibhere alinazo izitha emvelweni, ngaphandle kwabantu, njengoba kubonakala ezigabeni ezedlule, kungaba nzima kuye ukusinda. Kulula kakhulu ukuthi izilwane ezilusayo ziphile noma kunezinkinga eziningi. Ngisho namapheya amabhere amhlophe adalwe kuphela isikhathi sokukhwelana. Futhi, ngokungakhulelwa, insikazi ngokushesha ishiya owesilisa.
• Uma sikhuluma ngokukhulelwa, amabhere ase-polar anezinsuku ezingu-250! Isikhathi eside esanele sokululama ngokushesha kwesibalo sabantu, uyabona.
• Amawundlu angavela ngesikhathi esingekho ngaphezu kwesithathu. Yebo, kuvamile ukuba kuzalwe ithole lebhere elilodwa kuphela.
• Ukuthomba kumabhere amhlophe kwenzeka sekwephuzile kakhulu uma kuqhathaniswa nezinye izilwane. Okungukuthi, ngo-3, futhi ngisho neminyaka emi-4. Yiqiniso, amanye amabhere ayafa ngaphambi kokuba abe nesikhathi sokushiya inzalo.
• Ngokwezibalo, cishe amaphesenti angama-30 amawundlu ebhere afayo. Ngisho izilwane ezisanda kuzalwa. Uma kubhekwa inani elincane lenzalo insikazi ekwazi ukuyizala ngesikhathi esisodwa, lokhu kuningi.

Isilwane esizingelayo esikhulu esinekhono elihle lokuhogela, ukuzwa okubukhali namakhono amangalisayo okubhukuda - isilwane esinjalo singaba kanjani onqenqemeni lokushabalala? Kuvela, mhlawumbe! Mayelana nokuthi kungani, sitshele kulesi sihloko. Yebo, ngingathanda ukuthemba ukuthi isimo sizoba ngcono esikhathini esizayo.
