Wahi a Mizin, i hoʻokahi mau makahiki i hala aku nei, aia he 2-2.2 miliona mau mea ʻoi manu, a i nā manawa ma mua o ka mōʻaukala, ua ʻoi aku nā mea hou aku.

Ua hōʻike ʻo Mizin, ʻaʻole i lawe ʻia kēia mau ʻike honua eaahi, ka mea, e like me nā manawa Soviet, e uhi i nā pae āpau. "Aia kekahi hopohopo o ka nui o ka mea reindeer i loaʻa iā mākou ma luna o ka lehulehu. ʻAʻole mākou e loaʻa i ka ʻike hilinaʻi no kāna helu," i wehewehe ai ʻo ia.
No laila, ma ka māhele ʻo Murmansk ua hoʻi lākou i ka helu aerial i hoʻolālā ʻia i kēia manawa wale nō, ma hope o 15 mau makahiki o ke kohi. E like me ko TASS e kamaʻilio ʻia e Dmitry Kask, ke poʻo o ka ʻoihana a me ka mālama ʻana i nā mea holoholona maoli o ka Ministry of Natural Resources of the Murmansk Region, e hana ʻia kēia mau hana ma ka lā Malaki 2017.

"Ma nā māhele ʻEulopa o ka ʻāina, kahi ulu piha kaumaha me ka mea reindeer e noho ana ma nā ululāʻau. Massive deforestation and unprediseded poaching have led to a emi of number of animals by five to ten times," said Mizin.
Ma waho aʻe o nā Urals, ʻo ka hui nui o ka reindeer o ka nui i noho ma kahi o Krasnoyarsk Teritory - ma Taimyr.
"Ke manaʻo nei mākou i nā holoholona ma 400-500 tausani mau poʻo, ma 2000 ka nui o ka poʻe ʻōpio puaʻa i hōʻea i 1 miliona mau poʻo. I kēia manawa, ua kuhi.
