Pandas have lived earth for over three million years. Many species of animals that used to live together with pandas, such as the stegodon ( a kind of elephant with big tusks) and the Chinese rhinoceros, are extinct today. Now pandas are in danger,too Pandas used to live in many parts of China. and in a few oyter now they live in the mountains of southwesterns China. Today there are only about 1,600 giant pandas living in a wild Pandas live in bamboo forests in the mountains. They need to eat about 25-85 ponds(about 12-40 kg.) of bamboo every day and might spend up to 14 hours aday eating. They stop eating only when they need to sleep or travel short distances. Pandas can't live without bamboo. The number of pandas is getting smaller every year. One of the main reasons is the growing human population. People used to live in the villeys. but they are now moving into the mountains. They need places to live and places to grow food, so they are cutting the bamboo forests to build hourses and start farms. Consequently the bamboo forests are getting smaller and the panda population is,too.
