    Pandas do not have many babies, maybe only one  two years. The babies often die  illnesses and do not live very long. Adult pandas spend more than 12 hours a day eating about 10 kilos of bamboo. Many years ago, there were a lot  bamboo forests and pandas in China than there are now. But then humans started to cut  the forests, and there was less bamboo for the pandas. Scientists say there are now fewer than 2,000 pandas living in the remaining forests. Another 200  live in zoos or research centers in China and other countries.
