„Antrenamentul” sezonului în Arctica: Un urs polar folosește un bloc de gheață pe post de halteră

A polar bear was filmed using a block of ice as a weight during a unique training session in Svalbard, Norway. Photographer Paul Goldstein noted this unusual behavior, highlighting the bear's graceful swimming afterward. Climate change is impacting polar bear genetics, with rising Arctic temperatures potentially leading to the extinction of two-thirds of the population by 2050. Researchers found that environmental stressors may accelerate genetic adaptations, allowing bears to cope with harsher conditions and dietary changes. Bears in southeastern Greenland may gradually adapt to a plant-rich diet, unlike their northern counterparts.
