This concept is called white privilege and this book will help children of all races understand it, see how it affects them and find ways to speak out and take real action against it.
White Privilege: Deal with It in All Fairness provides scenarios, quizzes and Q&As that develop readers’ understanding of the subject using situations that are realistic and that easily relate to their everyday lives.

Dive deep into the world of this everyday insect -- and the science behind its uncertain future. Bumble bees are as familiar to most of us as the flowers these fuzzy insects feed upon. But did you know that the bees in your garden could be escapees from a local greenhouse, or descended from stowaways on a Viking ship?
Bumble bees are a vital part of our lives and Earth’s ecosystems, so much so that we’ve commercialized their breeding and shipped them across states, countries and ecosystems for our benefit. However, all of that human interference has consequences. Bumble bees are pushing out native species and altering ecosystems worldwide. Pesticide use has led to the spread of disease in local colonies. And some species may be disappearing entirely.
