竹子开花竟然会威胁到大熊猫的生存,这到底是怎么回事呢?用餐时间的大熊猫像个蹒跚学步的小孩,它坐在地上,两腿伸向身体前方,嘴里津津有味地嚼着竹子。大熊猫有力的上下颌与咀嚼力强大的大型臼齿——大约是人类牙齿的3倍大——使得它可以轻松地吃下坚韧的竹子。一天之内,它能像我们吃胡萝卜条一样容易地吃掉20~40磅重的竹子。一只大熊猫一年吃掉1万磅竹子。 The flowering of bamboo would threaten the survival of giant pandas.

The giant panda’s powerful upper and lower jaws and the large, powerful chewing teeth — about three times larger than human teeth — make it easy to eat tough bamboo. Within a day, it can eat 20 to 40 pounds of bamboo as easily as we eat carrot sticks. A giant panda eats 10,000 pounds of bamboo a year.
