Trees have been around for nearly 400 million years, and today about 25, 000 species of trees have been identified. We've relied on trees for everything from fuel, food, and medicine to building railways. Today, trees still touch our lives incountless ways. But what do we really know about them?Branching Out takes an in-depth look at these incredible plants, introducing the basics of tree biology and profiling 11 different trees from around the world, including familiar ones such as the red maple as well as lesser-known trees, like the tall-stilted mangrove. It showcases the inextricable ways trees are part of our society, culture, and economy. It also outlines how animals need trees – and sometimes even help trees survive through symbiosis. Full of useful facts and rounded out with a section on conservation, Branching Out is an essential primer that will leave young readers wanting to treat trees as well as they have treated us. | Branching Out by Joan Marie Galat, Hardcover | Indigo Chapters
