Time for kick off. It's polar bear football. Their ball control needs practice. But they are experts at dribbling 1. The game descends 2 into argument. The spycams return to the benches, the bears may be play-fighting, but things still get out of hand.
Meanwhile, on Svalbard, a kittiwake colony brings hope to the hungry mother and cub 3. They can't reach the nests, but there is still food to be had. Grass is the bears' emergency rations 4 and it flourishes wherever bird droppings provide fertilizer. It provides little real nourishment 5, but it helps stop hunger pangs 6. But to survive the bears will need protein.
In comparison, the ice bears have it easy, but the rising summer temperatures can cramp 7 a hunter's style. He's tracking bearded seals--an ambitious quarry 8. She has battle scars from a previous bear encounter. It won't be easy. The bear has two to choose from, the odds 9 are good. But he's treading on thin ice. He spreads his legs to distribute his weight and progresses carefully.
