Trees are everywhere and part of just about everything we do. We climb them, swing from them, eat under them, pick fruit from them, use them to build houses and fires, read books and write letters using materials made from them, and enjoy the birds and animals that nest in their branches. They provide oxygen for us to breath and absorb many of the pollutants we emit. Their existence is essential to ours, and there are many interesting facts for kids to learn about them.
