Protecting China’s Giant Panda

China’s giant panda shows the achievement of the international effort to save animals that are now in danger. In television programs we often see pandas  1  funny games. Children have panda toys and beautiful cards with pictures of lovely  2  in them. They often visit the giant pandas in the zoo on  3  holidays and have a good time there. However, scientists are worried about the  4  of giant pandas. They know only about 1 000 giant pandas remain  5  today. They think the giant panda will die out in 30 years if the present conditions are not  6  .

It is reported that the giant pandas have a very  7  birthrate. About 115 pandas live in zoos and research centers mainly in China, but during the past 10 years they  8  only 34  9  pandas that are still alive. Survival rate for giant pandas in the wild are probably the same or lower.

There are several reasons for the low  10  . The main reason is  11  male pandas can make love with females in a very  12  season—only a few days a year. When they do have babies, females often produce two pandas, but the mother is usually not able to care for  13  of them. The newborn pandas  14  only a few kilograms each. They are too weak to live without special care. In the zoo, scientists can help the mothers  15  the young pandas, but those living in the wild do not get enough  16  . It is very difficult for mother pandas to bring up their young pandas.

Conditions for the giant pandas have been worse in recent years. Pandas in China continue to  17  in number. We know pandas live on bamboos. But sometimes all the bamboos in one area die. The pandas there have  18  to eat and die of hunger.

Giant pandas now live in 13 separate  19  areas in China. Several years ago the Chinese government and the International Wild Life Organization agreed  20  a project of protecting giant pandas in the wild. We hope it could be helpful.
