In China, people and giant pandas had been living together for thousands of years. But China’s human population has been great growing. More population means more land is needed for farming. It also mean more forests are cut for wood to build and heat houses. Loss of habitat in lowland areas has forced pandas live only in the mountains. The most damaged result of development has been that it has divided the panda’s habitat into little islands of forest. Today, many panda are isolated in these small sections of forest, because of they will cross into areas which people live. The result is that the giant pandas can connect with one another to mate and have babies.
Besides, to our relief, there is still some good news that people are trying to help the giant pandas by creating protected areas.
