Sei chiyero chembeu yepollar muActic inoderedzwa?

Muchena, kana polar, bheya - mhuka ine simba uye yakaisvonaka, chiratidzo chaicho cheArtictic. Kunyange zvakadaro, vagari vomunharaunda vanogara kuNorth vakanga vari pangozi. Nhamba yezvikwata zve polar muActic mumakore achangopfuura zvakaderera zvikuru. Masayendisiti anotaura kuti muhafu yezana remakore vangasave vari pasi redu zvachose. Muna 2008, bheya yepollar yakarondedzerwa kuti yaiva mungozi, uye yakapinda muRubhuku Bhuku.

Sei nhamba yezvirimwa zve polar zvichiderera?

Masayendisiti-vezvokurapa anopa zvikonzero zvakasiyana zvekuderera kwehuwandu hwembeu dzepurasitiki. Pakati pavo, zvinhu zvepanyama uye anthropogenic zvinogona kusiyaniswa.

Chimwe chezvikonzero chikuru nei huwandu hwembeu dzepurasitiki dziri kuderera ndiko kupisa kwemamiriro ekunze uye kuparadzaniswa kunobatanidza munharaunda yeparlar ice. Uye izvi zvinokanganisa hupenyu hwebheri rebheri, sezvo iyi mhuka inorarama nekuvhima zvisimbiso. Kwemakore makumi matatu apfuura, nzvimbo yechando muActic Ocean yakaderera kusvika ku 5.02 mami square mita. Km kurwisana nevhareji ye mamiriyoni manomwe emamita mita. Km.

Kupisa kwemamiriro ekunze

Kushanduka kwemamiriro ekunze kwakatungamirira kukudziya kwemvura munzvimbo iri kumaodzanyemba kweActic Ocean. Imwe hove inotonhora inotonhora (somuenzaniso, saika) yaenda kune dzimwe nzvimbo dzekumusoro. Uye kumashure kwavo kwakafamba uye vanhu vezvisimbiso zvinonamatira, izvo zvinovhimwa nebheri yebere. Chikamu chembhesi yakasara shure kwezvisimbiso kusvika kuchamhembe, uye vamwe vose vari kutarisana nematambudziko makuru nekudya. Somugumisiro, mhembwe dzinotanga kudya kwete zvokudya zvavo zvinowanzoitwa - shiri mazai, lemming, mabriji.

Mhuka dzine nzara dziri kuwedzera pakuuya kwevanhu. Mukutsvaga kwezvokudya ivo vanopisa marara emarara uye marumusi, ingozi kune vanhu. Mhuka dzakadaro dzinopfurwa, izvo zvinotsanangurawo kuti sei nhamba yezvikwekwe zve polar iri kuderera.

Uyezve, vachidya zvokudya zvakasvibiswa, vanowanzomedza uye zvinhu zvinotyisa sefirimu ye polyethylene, mambure enylon yezvokudya, zvikamu zvegirasi, yakagadzirirwa nemasara emishonga emumba.

Lifestyle

Ichi chine simba uye chinokanganisa chinotungamirira mararamiro anorasika. Muchirimo, apo yechando inotanga kunyauka, hutumburu hunoenda kumaodzanyemba. Kubuda kubva kuchando kunotenderera kusvika kuchando, vanoita nguva refu. Mumvura yechando vanodhakwa panguva yekuvhima kana kutamira pane imwe yezaya.

Kupisa kwemamiriro ekunze kwakakonzera kuti iyo inoguma ice inowedzera uye yakasimba. Iyo inoputika nyore nyore uye inogumbusa kana yakarohwa. Nokudaro, zvibato zve polar zvinofanira kushambira marefu marefu kupfuura kare. Izvi zvinosanganiswa nehuwandu hwemhepo yakawanda, zvinoreva kuti zvimwe zvokudya zvinodiwa kuti uwane. Mudiki haagoni kungokunda rwendo rwakadaro uye kunyura.

Nemhaka yezvakachinja mazaya echando, mazhinji emabhere haana nguva yokudzokera kunyika kuti aenderere mberi. Vanowedzera, vanomanikidzwa kugadzira dzimba dzemadzinza zvakananga pamusoro pechando, izvo zvinowedzera mukana wekufa kwevana vaviri nebere. Zvechokwadi, kutaridzika kwemakumbo uye kuidya kunotora simba rake rakawanda, uye haagoni kubva muhova nekuvhima kusvikira vana vachigona kumutevera.

Kuvhima

Chimwe chikonzero nei huwandu hwembehwe dzepurasitiki dziri kuderera ndekudzivirira. Apo vainge vari chinhu chokuvhima vagari vashomanana vagari vemuNorth, zvakanga zvisingaonekwi. Asi apo hutoro hwakatanga kuvhima nezvombo zvemazuva ano, kushandisa helicopter, nhamba yemhuka yemapfupa yakawedzera zvinoshamisa. Yakarongeka mazendo akazara ekuvhima bhechi yebhiri. Uye ganda reAlctic mhondi yakafa raive rakazviratidza kune vaenzi.

Iyezvino bere rebheri rinorindirwa, asi kune vanyori izvi haisi chipingamupinyi.

Zvirwere

Masayendisiti vari kuedza kujekesa zvakajeka nei chiverengero chezvirimwa zve polar chiri kuderera. Mhinduro dzacho dzakasiyana. Pazvikonzero zvinokonzerawo zvirwere, somuenzaniso trichinosis. Inokonzera zvirwere, kugadzikana mumisungo yemhuka. Mukuwedzera kune mabheji emapuranga, vanorwara nehunze dzeArctic, mbwa dzakanyungudutswa, zvisimbiso. Vamwe vanhu vanofunga kuti vanhu vakauya nehosha iyi kuNorth.

Hapana mubvunzo kuti mabheya emapuranga anoda kudzivirirwa. Kana zvisina kudaro, vazukuru vedu vangave vasingazivi nezvechikara chakashamisa uye chinoshamisa, nomad weArctic, uyo aigara muHurth North.
