The teeth start the breakdown process of the food the bear eats. They eat anything from leaves, roots, and berries to insects, carrion, fresh meat, and fish, and have digestive systems and teeth adapted to such a diet. The Sichuan Giant Panda Sanctuaries, which are home to around 30% of the wild panda population, gained a UNESCO World Heritage Site designation in 2006.

[117], Laws have been passed in many areas of the world to protect bears from habitat destruction. [13], The earliest members of Ursidae belong to the extinct subfamily Amphicynodontinae, including Parictis (late Eocene to early middle Miocene, 38–18 Mya) and the slightly younger Allocyon (early Oligocene, 34–30 Mya), both from North America. [55] The sun bear's range extends below the equator in Southeast Asia. During this time period, males try to prevent rivals from interacting with their mate. 4 .

[31], There are two phylogenetic hypotheses on the relationships among extant and fossil bear species. [44] A fecal plug is formed in the colon, and is expelled when the bear wakes in the spring.
