V naslednjih 35 letih naj bi \u0161tevilo polarnih medvedov upadlo za 30 odstotkov. Do enakih ugotovitev so pri\u0161li tudi v drugih \u0161tudijah. Nenazadnje je o tem nedavno v \u0161tudiji pisala tudi Mednarodna unija za ohranitev narave (IUCN), ki spremlja ogro\u017eene \u017eivalske vrste, poro\u010da francoska tiskovna agencija AFP.<\/p>\n

IUCN je polarnega medveda uvrstila med “ranljive” \u017eivalske vrste, ki jim grozi, da bodo v divjini povsem izumrle.<\/p>\n

V novi \u0161tudiji, ki jo je objavil dnevnik Royal Society’s Biology Letters, so primerjali satelitske podatke zadnjih 35 let in gibanje 19 skupin polarnih medvedov. “Polarni medvedi so odvisni od ledu v morju,” so zapisali v \u0161tudiji. Medvedi denimo uporabljajo plavajo\u010de ledene ploskve za lovljenje ali plavanje na odprto morje.<\/p>\n

Skupina strokovnjakov je predvidela tri scenarije do sredine stoletja, po vseh pa se polarnim medvedom ne pi\u0161e ni\u010d dobrega. Vsem scenarijem je skupno, da \u0161tevilo medvedov mo\u010dno upada zaradi taljenja ledu, kar je posledica globalnega segrevanja ozra\u010dja. \u0160tevilo polarnih medvedov naj bi se za tretjino zmanj\u0161alo v 35 do 41 letih, za kar je 70-odstotna verjetnost, je glavna ugotovitev \u0161tudije.<\/p>\n","protected":false},"excerpt":{"rendered":"
