「這是一本STEM的繪本。STEM在定義上本來就含括好奇心、求知欲、行動力。簡單地說，就是堅持做對的事！STEM的精神不是只了解環境和它形成的因素，更重要的是參與和實踐。」《Footprints across the Planet》的作者，美國科學師鐸獎得主（NSTA) Jennifer Swanson如是說。 她在接受《圖書館學報》的專訪裡説：「我一向只寫1萬字的書。但這僅有150個單字的STEM繪本，匯整、串連了我對於自然、歷史、科技、社運的核心價值和熱情。」 「從2017年3月的『為科學遊行』，到瑞典環保少女Greta Thunberg的『氣候大罷課』，以及首位猶太裔女性大法官 Ruth Bader Ginsburg在美國文學節上精彩的演說，這些有形、無形的『足跡』，我希望讀者們從我的文字裡看到這些『足跡』的影響力，也思考自己能為這世界做些什麼。」

Every footprint―from the physical to the digital and the permanent to the fleeting―leaves a mark on Earth telling a story of the past, the present, or the future. What type of imprint will YOU leave?

Journey around the world and experience through these vivid photographs how every being on the planet leaves an imprint, with their feet, their words, their actions.
