The beauty and breadth of Boreal Forests is integrated by an environmentalist theme.
While this book is filled with many interesting facts and explanations of the Boreal biome, its environmentalist zeal undercuts its value to its juvenile audience. Envronmental issues are technical and philosophical, at a level that high school graduates are not yet equipped to properly understand. Specious claims take advantage of that audience, e.g. their argument claiming the Boreal Forests are the "lungs of the Earth" (see full review).
