The Nature Generation announced the 2016 Green Earth Book Award winners nearly two months ago. The good thing about being late mentioning this means that I'm giving these books some new attention after talk of the award is in the past.
The Stranded Whale by Jane Yolen with illustrations by Melanie Cataldo won for best picture book.
The Thing About Jellyfish by Ali Benjamin won for best children's fiction. By the way, it was also a National Book Award finalist.
Mission: Sea Turtle Rescue by Karen Romano Young (Facebook friend) and Daniel Raven-Ellison.
The Beast of Cretacea by Todd Strasser won for young adult fiction.
