A USGS & NPS study finds each Yellowstone grizzly generates about $46,000 a year in local economic value from wildlife viewing alone. Proof that wild nature pays its own way — and that every bear is worth far more alive than dead.

Scientists once speculated polar bears may enter a state of “walking hibernation” during fasting periods, but research disproved this. They lack the ability to withstand long fasts by triggering physiological changes like those seen in hibernating animals. pbears.org/4dOYGJZ
