For example, if people made barbecue in the wild, the good smell of the food will attract both human’s and animals’ attention. On the other hand, if the food taste awful or it has a strong scent, such as the hot pepper or garlic, most human and animals will avoid it. Therefore, it is thought that the reason the giant pandas eat lots of bamboos, instead of meat, is because the giant pandas think the bamboos is more delicious or taste. However, according to Jin et al.(2011), we need to look beyond taste to understand the driving force for the panda 's diet to answer this question. First of all, Jin et al.(2011) stated that taste is not the only reason that can affect animals ' eating behaviors. In order to survive, most animals will choose the food with relatively higher energy and nutrition. Smell and taste are the additional properties of their food(para.5). Therefore, for the giant pandas, the taste and smell may not be the primary reason that drives them to consume bamboos. Moreover, Jin et al.(2011) believed that the lack of available meat in their habitat is not a main reason either. For instance, in Qinling mountains, there are other animals such as rabbits and foxes living in the same area, and the giant pandas can easily pray them taking advantage of their large body …show more content…
Because the understory bamboo is an inevitable part of the Eco-forest system. First of all, bamboo is good for erosion soil. Erosion is a major environment threat to the agriculture and becomes a worldwide problem(Zhou, Fu, Xie,Yang and Li, 2005, p.143). However, bamboos can stop this. According to Zhou, Fu, Xie,Yang and Li(2005), bamboos’ root system may produce the soil surface, and its dense foliage can protect against the rains and produce new culm from underground which prevent the soil(p.143). Second of all, bamboos is good at holding the soil. Zhou, Fu, Xie,Yang and Li(2005) believed that the massive roots of bamboos can hold the soil very well. Moreover, bamboos can also protect the riverbank and prevent landslides. Zhou, Fu, Xie,Yang and Li(2005) said that “the fibrous mass of roots binds the soft banks, and the thick culms arrest strong currents during flood
