There are many factors contributing to the extinction of Giant Pandas all over the world. One of the main factors is the deforestation of many Chinese forests in which pandas live, for both logging and agricultural settling. In a country where the population is expanding at a rate far faster than its natural resources and land can handle, panda population has been put on the back burner. Now that humans inhabit most valleys in China, some natural panda habitats are now wider than 1000 meters. In the 1980s, several studies showed that panda habitats had decreased from 29500km2 to 13000km2, which some scientists fear may lead to the fragmentation of habitat. This would cause the isolation of small numbers of pandas in any given region and thus inbreeding problems.
Another large factor in panda extinction is illegal hunting and poaching. Pandas have a very slow reproductive cycle and the killing of one can severely damage the process. Even with China's severe penalties, both in terms of imprisonment and fines, poaching still continues in China today. Another problem that occurs is that pandas get trapped and killed in traps set up for other animals, such as the Musk Deer.
A natural threat to pandas is a phenomenon called "Bamboo Die-back", in which the bamboo dies and replants itself after flowering. This can occur every 15-120 years, depending upon the species of bamboo, after which it can take as long as 15 years for the new bamboo to be able to support a panda population.
