    It has also been included in the New York State Expeditionary Learning English Language Arts Curriculum. Written by a master storyteller, World Without Fish connects all the dots—biology, economics, evolution, politics, climate, history, culture, food, and nutrition—in a way that kids can really understand. It describes how the fish we most commonly eat, including tuna, salmon, cod, and swordfish, could disappear within 50 years, and the domino effect it would have—oceans teeming with jellyfish and turning pinkish orange from algal blooms; seabirds disappearing, then reptiles, then mammals. It describes the back-and-forth dynamic of fishermen and scientists. It covers the effects of industrialized fishing, and how bottom-dragging nets are turning the ocean floor into a desert. The answer? Support sustainable fishing. World Without Fish tells kids exactly what they can do: Find out where those fish sticks come from. Tell your parents what’s good to buy, and what’s not. Ask the waiter if the fish on the menu is line-caught And follow simple rules: Use less plastic, and never eat endangered fish like bluefin tuna. Interwoven with the book is a graphic novel. Each beautifully illustrated chapter opener links to form a larger fictional story that complements the text. Hand in hand, they create a Silent Spring for a new generation.

    Unlikely Friendships tells one story after another of animals who, with nothing else in common, bond in the most unexpected ways and thrive on the warmth, closeness, and trust that come with being true friends.Imagine a predator cuddling its prey. Or a bird befriending a mammal. Or a fish poking its nose out of the water to nuzzle a dog. Or a massive gorilla - the one named Koko, famous for her ability to communicate in sign language - embracing a tiny kitten.Science writer Jennifer S. Holland narrates each story, and also offers insights into these relationships. Sometimes there are plausible scientific explanations: an orphan seeking comfort from an older animal; an adult yearning for a younger creature to nurture. Consider the lioness who befriended and protected a baby oryx - unexpected, but not inexplicable. Sometimes a friendship is about need, as in the case of the blind Lab and her "seeing-eye" cat. B ut sometimes it's just a lovely mystery. How else can one explain the story of Owen the hippo and Mzee the tortoise, two notoriously surly creatures who became bosom buddies?Each story reveals the true power of friendship and, to some degree, the many forms of "love" that seem to exist in the animal kingdom. Yes, scientists might scoff at that notion, but readers may feel a little differently about the world after they finish this book.
