All she can do is keep trying. To prevent her scent betraying her, she makes a wide sweep to get downwind of the seal. Getting close. She's now right behind the seal. Incredibly, she caught the seal underwater. It's only small, but even so, its blubber alone will contain 100,000 calories, enough to sustain this bear for a week. And, in that time, she might even catch another. But this can't go on forever. As summer continues, temperatures are rising. Each hunt requires more energy, draining the bears of their reserves.
