Kungani incipha inani amabhere e-Arctic?

White, noma polar bear - isilwane esinamandla futhi enhle, iwuphawu Arctic kweqiniso. Nokho, izakhamuzi zabomdabu Ngasenyakatho wasongelwa. Isibalo amabhere e-Arctic yehlile kakhulu kule minyaka edlule. Ososayensi bathi nengxenye ngemva kweminyaka eyikhulu banganifundisi uhlale emhlabeni. Ngo-2008, i-polar bear umenyezelwe lwezilwane ezisengozini, ngikulethile eNcwadini Red.

Kungani incipha inani amabhere?

Ososayensi, Izazi ukunikeza izizathu eziningana ukunciphisa la mabhere esemaningi. izici zemvelo kanye yabantu ungabahlukanisa phakathi kwabo.

Esinye sezizathu eziyinhloko kunciphisa inani amabhere, kungenziwa kubhekwe njengento yokufudumala kwembulunga yonke futhi ukwehliswa ezihlobene endaweni kweqhwa elimboze izindawo ezibandayo. Lokhu kuthinta kakhulu empilweni lo polar bear, njengoba lokhu isilwane iphila abazingela ezingela izimvu zamanzi. Kule minyaka engu-30 edlule, endaweni leqhwa Arctic Ocean wenqulu laya ezigidini ezingu-5.02 metres square. km vs. inani eliyisilinganiso phezu sq abayizigidi ezingu-7. km.

sezulu ukufudumala

Ukushintsha kwesimo sezulu kuye kwaholela ukufudumala yamanzi sesihlasela ingxenye eseningizimu ye-Arctic Ocean. Ezinye izinhlanzi coldwater (isib, Arctic cod) sebengenwe ezindaweni ezingaphezulu enyakatho. Futhi ezingqondweni zabo futhi baqhubekela labantu lwezimpawu ringed, okuyinto babezingelwa polar bear. Ingxenye amabhere aya lwezimpawu enyakatho, kanti bonke abanye ahlangabezana nobunzima omkhulu ngokudla. Ngenxa yalokho, amabhere uqale ukondla hhayi ukudla kwabo evamile - izinyoni 'amaqanda, lemmings, amajikijolo.

izilwane abalambayo ngokuya ukuza uhlalwe ngabantu. Ziyofuna ukudla, athungatha imfucumfucu landfills, kuyingozi abantu. izilwane ezinjalo esingu, ukuthi futhi kuchaza ukuthi kungani inombolo ukuncipha namabhere.

Futhi, ukudla ukudla udoti, bavame ukugwinya izinto eziyingozi, ezifana ifilimu plastic, inayiloni anezikhala imikhiqizo, izingcezu ingilazi, utshani izinsalela amakhemikhali yasendlini.

indlela yokuphila

Lesi silwane esinamandla futhi beshesha kuyinto abangondingasithebeni. Entwasahlobo, lapho iqhwa uqala zincibilika, amabhere ukuya enyakatho. Iyazulazula kusukela ice floe ice floe, benza eside ukweqa. Amanzi ice bona ngena phakathi wokufuna noma ukuba bathuthele kwelinye floe ice.

Climate ukufudumala kuye kwaholela yokuthi iqhwa okuholela kuba ohlabayo nokuncane okuhlala. Yena kalula ahlahlele futhi Liyashabalala phezu umthelela. Ngakho-ke, amabhere kufanele ngibhukude amabanga amade kunangaphambili. Lokhu kungenxa ugwadule olukhulu amandla, izindlela, futhi ukudla nokuvulwa ithatha isikhathi eside. Izinsizwa nazo nje ngeke amhlule uhambo olunjalo futhi minza.

Ngenxa yalezo zimo ice ekushintsheni amabhere amaningi ayengafuni uphathe ukubuyela ezweni ukuqhubeka esemncintiswaneni. Bayanda banayo sokumba womama zinemiphandu ngqo ice, okwandisa ingozi yokufa futhi izingane, futhi ibhere kakhulu. Ngemva ukubukeka amawundlu, futhi yokudla wabo uyamthatha eziningi amandla, uphume zinemiphandu yabo yokuzingela ngeke nje izingane ngeke ukwazi ukusilandela.

ukuzingela

Esinye isizathu ukuthi kungani inombolo ukuncipha amabhere kuyinto ngezinhlamvu zezibhamu zokuzingela. Nakuba babezingelwa nje ezimbalwa zabantu bomdabu of the North, kwakungeyona lubonakale. Kodwa lapho amabhere beqala ukumfunisisa nge izikhali zanamuhla, usebenzisa izindiza ezinophephela emhlane, inani izilwane esingu liye landa ngendlela emangalisayo. izinkambo Ukuhlelelwa lonke yokuzingela namabhere. Futhi isikhumba nomzingeli Arctic ababulewe ngokuqhosha yabonisa izivakashi.

Manje polar bear kuyinto evikelwe, kodwa abazingela ngokungemthetho ke akusona isithiyo.

isifo

Ososayensi bazama ukuthola ngokunembile ukuthi kungani inciphise inani namabhere. Izimpendulo zihlukile. Esinye sezizathu ke ubizwa nangokuthi izifo ezifana trichinosis. It is esibangelwa amagciwane, ukuyohlala imisipha izilwane. Ngaphezu amabhere, bona usathola izimpungushe ogulayo, nezinja ezidonsa izihlibhi, izimvu zamanzi. Abanye bakholelwa ukuthi lesi sifo ngiyikhiphile abantu North.

Akungabazeki ukuthi amabhere adinga isivikelo. Kungenjalo, abazukulu bethu bangawutholi nanini ukwazi isilo abayimizulane eqinile ngokumangalisayo enhle Arctic owaphila North nokhahlo.
