In this thought-provoking compilation, prolific author Eric Walters takes a unique approach to exploring how young people can make a difference in the world. His imaginary stand-in, a curious child named Jo, asks how people can be so cruel to each other, why so many bad things happen, and, most importantly, what one person can possibly do to help. Well-known Canadians, including Craig Kielburger and Maude Barlow, share their suggestions, as do international activists such as Jane Goodall.

Each response starts with a brief biography, followed by a letter to Jo offering personal experience, advice, and further questions. Some letter-writers talk about global tragedies, others discuss more personal experiences. Each explores the reasons behind and the effects of these crises, and the steps he or she took to create change.

One of the book’s strengths – and it has many – is its refusal to sugar-coat or alter the material for a younger audience. Roméo Dallaire saw people die, Kim Phuc felt her skin burned off by Napalm, and they describe those experiences for the reader. Maude Barlow doesn’t simplify her vocabulary when she refers to complex issues such as the problems of a “materialistic, competitive and hierarchical society” or “income disparities.” Young readers are treated with respect, an approach that is particularly important in a book that wants to encourage its audience to tackle challenges that even adults don’t seem able to resolve.

Also effective are Walters’ profiles of five young Canadians who have taken on causes ranging from homelessness to cancer research to clean water in Africa. These stories of resourcefulness and resolve serve as a reminder that anyone can bring about change, no matter how young or unconnected they may feel themselves to be. Tell Me Why effectively answers the titular question and inspires action.
