Trees

Trees are an important part of our world.  They provide wood for building and pulp for making paper.  They provide habitats (homes) for all sorts of insects, birds and other animals.  Many types of fruits and nuts come from trees.  Even the sap of trees is useful as food for insects and for making maple syrup. Trees also help to keep our air clean and our ecosystems healthy.  We breathe in oxygen and breathe out carbon dioxide.
