      Do you know how many pandas there are in the world? World Wildlife Fund (WWF) has spent four yours counting pandas in the world. It says there are 1,590 now. In the 1980s, there were only 1,100.

So we may say that pandas are lucky because people around the world love them and are trying their best to help them. However, we also say that pandas are unlucky because they are still facing a lot of problems now.

Pandas are not good at making babies. Even in the wild, scientists have found that female pandas give birth only every 28 months. That's why the number of pandas goes up so slowly.

Pandas need bamboos for food, but bamboo dies every 10 to 100 years. It can take up to 20 years to provide(提供) food for pandas. When bamboo dies, pandas have to move to other areas. In the past, this was easy. However, the number of people keeps growing, people cut down more forests and built more villages. It's more difficult for pandas to find bamboos and homes than before.

In the past years, WWF made great efforts to protect pandas. And some Chinese scientists are also always trying to find ways to help pandas.
