Peas on Earth uses a simple play on words to portray the basic concepts of peace, harmony, getting along with all kinds of people, and being green in a manner that young kids will grasp. And it will resonate more as they grow older. Adult caregivers will chuckle over the peas/peace references while young children will relate to the important messages about our earth and those of us who live on it. Â The artwork is colorful, charming, and perfect for the board book crowd. And, as an added value, there is a simple pop-up at the end of the book.
