Change – take out deciduous tree:  If there were no deciduous trees, people would have no lumber  The squirrels would have no acorns for food  Birds would have no food or homes  No oxygen for people and animals  People would have no wood  If there were no leaves, soil would not be rich for farming  Less paper supplies

8. Other interesting facts:  Some threats to deciduous forest are air pollution and acid rain  In Asia and Europe, the deciduous forest is vast
