Everything that we need, Earth provides. All across our planet, plants grow. Earth's forests and plants are one of our valuable natural resources. We pick their fruit, leaves, and seeds for food. We cut their wood for lumber. We harvest them for medicine. Even when we do nothing, plants give us oxygen to breathe. Natural resources are a gift from Earth, but we must use them responsibly. Just as Earth takes care of us, we must take care of its plants. Color photographs, fact boxes, a hands-on activity, and 'Words to Know' round out this earth science volume.
