panda changes (to discourage deforestation and save the pandas)

pandas now have a hunger bar, and will break down bamboo trees to eat the bamboo when they get hungry, however, when they do, the bamboo will also be re-planted. this way, if the bamboo is all destroyed, then the pandas can go extinct like they are in danger of in real life, however, with some slight effort of replanting/relocating the bamboo forests, you can save the pandas! This reflects real life and will discourage the destruction of the panda's home and help save the pandas.
