kwanyengo nyengo

Kusintha kwa nyengo kwachititsa kuti kutentha kwa madzi mu kum'mwera kwa Ocean Arctic. Ena coldwater nsomba (mwachitsanzo, Arctic m'nyanja zikuluzikulu) apita ku madera ambiri a kumpoto. Ndipo n'kumapitiriza anthu a zisindikizo ringed, amene ankasakidwa chimbalangondo kumalo ozizira. Part zimbalangondo anapita kwa zisindikizo kumpoto, ndipo ena ali m'mavuto kwambiri ndi chakudya. Chifukwa, zimbalangondo kuyamba kudyetsa osati chakudya mwachizolowezi - mbalame mazira, lemmings, zipatso.

Njala nyama kunadetsa kubwera kwa anthu azikhalamo. Mu chakudya, iwo ankafufuza zinyalala ndi landfills, ndi oopsa kwa anthu. nyama oterowo anawomberedwa, kuti N'chifukwa chakenso yafupika nambala ya zimbalangondo.

Komanso, kudya chakudya zinyalala, kawirikawiri kumeza ndi zinthu loipalo, monga filimu pulasitiki, nayiloni mauna zopangidwa, zidutswa za galasi, udzu zotsala za mankhwala banja.

njira ya moyo

Wamphamvu ameneyu ndi agile nyama ndi vagrant. M'chaka, pamene ayezi akuyamba kusungunuka, zimbalangondo kupita kumpoto. Akungoyendayenda kwa ayezi floe kwa ayezi floe, iwo yaitali kudumpha. Ayezi madzi iwo kuyenda pansi pa madzi pa kusaka kapena kusuntha kwa wina floe ayezi.

kwanyengo nyengo kwachititsa chakuti ayezi chifukwa amakhala n'kakang'ono ndi wochepa cholimba. Iye mosavuta chisoni ndi silimba pa amadza. Choncho, zimbalangondo kusambira mitunda yaitali kuposa kale. Ichi ndi chifukwa ndikungowononga yaikulu mphamvu, njira, ndi chakudya cha ayambe imatenga nthawi yaitali. Young komanso sitingapeze kugonjetsa ulendo ndipo adzawonongedwa.

Chifukwa cha kusintha kwa zinthu ayezi zimbalangondo ambiri sakwanitsa kubwerera kudziko kupitiriza mpikisano. Makamaka, iwo ali kukumba umayi mapanga mwachindunji pa ayezi, amene kumaonjezera ngozi ya imfa ndi ana, ndipo ambiri chimbalangondo. Pambuyo kuoneka ana, ndi kudyetsa iwo amugwila kwambiri mphamvu, ndipo tuluka mwa mapanga awo kusaka sizingausunge bola ngati ana sadzatha kuti aziwatsatira.

kusaka

Chifukwa china chimene chepetse chiwerengero cha zimbalangondo ndi poaching. Pamene anali ankasakidwa basi ochepa anthu a m'dziko la North, izo sizinali noticeable. Koma pamene zimbalangondo anayamba kusaka ndi zida zamakono, ntchito Helicopters, chiwerengero cha nyama anawomberedwa chawonjezeka kwambiri. Gulu maulendo kwa kusaka lonse la zimbalangondo. Ndipo khungu la ophedwa Arctic chilombo ndiye monyadira anasonyeza alendo.

Tsopano chimbalangondo kumalo ozizira ndi otetezedwa, koma anthu opha nyama si chopinga.

matenda

Asayansi akuyesa molondola kwambiri kudziwa chifukwa chepetse chiwerengero cha zimbalangondo. mayankho zosiyana. Zina mwa zifukwa umatchedwa komanso matenda monga trichinosis. Iwo amayamba ndi majeremusi, yothetsa mu minofu ya nyama. Kuwonjezera zimbalangondo, iwo akupeza nkhandwe odwala, agalu sled, zisindikizo. Ena amakhulupirira kuti matenda kwachititsa anthu ku North.

Palibe kukaika kuti zimbalangondo amafuna chitetezo. Apo ayi, adzukulu athu akhoza kudabwa za amphamvu ndi n'zosadabwitsa wokongola chirombo wongosamukasamuka Arctic amene ankakhala North nkhanza.
