其内在原因是由於食性、繁殖能力和育幼行为的高度特化。外在原因则是栖息环

The reason is due to its inherent high degree of feeding, breeding and nursery capacity behavior of specialization. External cause is habitat destruction, the formation of island-like unconnected, resulting in population segmentation, inbreeding, species degradation. <br><br>Blind due to human activities, so habitat destruction, resulting in habitat area reduction. <br><br>Panda single food source, eating bamboo, bamboo once destroyed, its survival will be affected. <br><br>Panda itself reduced reproductive capacity, reproductive system subject to certain bacterial infections, reduce the rate of spawning females, male mating desire to reduce, which is leading a major cause of panda is about to extinction. <br><br>The lower the survival rate of panda baby. <br><br>Panda's strong dependence on the place of residence, poor adaptability to environmental changes. .

Its intrinsic cause is the high degree of specialization of food, reproductive capacity and child-rearing behavior.<br><br>The external cause is that the habitat environment is destroyed, forming isolated islands, leading to population segmentation, inbreeding, species degradation.<br><br>Human seunactivity has destroyed its habitat, resulting in a reduction in its habitat area.<br><br>Pandas have a single source of food, eating only bamboo, and once bamboo is destroyed, its survival will be affected.<br><br>Pandas' own reproductive capacity is reduced, its reproductive system is infected by certain bacteria, female spawning rates are reduced, and males' mating desire slower, which is also a major cause of the panda's imminent extinction.<br><br>The survival rate of baby pandas is low. Pandas are more dependent on their place of residence and less adaptable to environmental change.

The intrinsic reason is the high specialization of feeding habits, reproductive capacity and childrearing behavior. The external reason is that the habitat environment is destroyed, resulting in the formation of unrelated islands, resulting in population segmentation, inbreeding and species degradation.<br>Because of the blind activities of human beings, their habitats have been destroyed, resulting in the reduction of their habitat area.<br>Pandas have a single source of food, only eat bamboo, once the bamboo is destroyed, its survival will be affected.<br>Panda's reproductive capacity is reduced, its reproductive system is infected by some bacteria, the female's oviposition rate is reduced, and the male's desire for mating is reduced, which is also a major reason for the imminent extinction of pandas.<br>The survival rate of baby pandas is low.<br>Pandas are highly dependent on their habitats and less adaptable to environmental changes.<br>
