Trees are very important because they bring oxygen to the world and they grow fruit so we can eat. Also they provide lots of wood. They can provide shade when we are hot. People can exercise by climbing a tree. Also they can color the world. Not all trees are the same. Some are big, some are small. Some are wide, some are skinny and yet they all belong! No matter how big, how small, how wide, and how skinny, they all belong.
