From chapter Tree hugger ​

Answer 1

Answer:

Human beings are just one leaf of the appoximately 1,750,000 on the Tree of Life that represents all the species that make up Life on Earth. Taking the model of th e tree, this great book introduces children to biodiversity and the impact that even tiny changes within one species can have on ther leaves, twigs amd/or branches. it's packed with bites of information, numbers and ideas about 'Becoming Guardians of the Tree of Life. Labelled close-ups of species emerge from the tree, each drawn on their own leaf - and the diagram of the tree showing how much is taken up by each category of species is particularly effective. It is the perfect companion to other books in Kids Can Press's CitizenKid series.
