By some estimates, we may already have lost almost half of the songbirds that filled the skies only forty years ago. Renowned biologist Bridget Stutchbury convincingly argues that songbirds truly are the "canaries in the coal mine"--except the coal mine looks a lot like Earth and we are the hapless excavators.Following the birds on their six-thousand-mile migratory journey, Stutchbury leads us on an ecological field trip to explore firsthand the major threats to songbirds: pesticides, still a major concern decades after Rachel Carson first raised the alarm; the destruction of vital habitat, from the boreal forests of Canada to the diminishing continuous forests of the United States to the grasslands of Argentina; coffee plantations, which push birds out of their forest refuges so we can have our morning fix; the bright lights and structures in our cities, which prove a minefield for migrating birds; and global warming. We could well wake up in the near future and hear no songbirds singing. But we won't just be missing their cheery calls, we'll be missing a vital part of our ecosystem. Without songbirds, our forests would face uncontrolled insect infestations, and our trees, flowers, and gardens would lose a crucial element in their reproductive cycle. As Stutchbury shows, saving songbirds means protecting our ecosystem and ultimately ourselves.Some of the threats to songbirds: - The U.S. annually uses 4-5 million pounds of active ingredient acephate, an insecticide that, even in small quantities, throws off the navigation systems of White-throated sparrows and other songbirds, making them unable to tell north from south. - The U.S. Fish and Wildlife Service conservatively estimated that 4-5 million birds are killed by crashing into communication towers each year.- A Michigan study found that 600 domestic cats killed more than 6,000 birds during a typical 10-week breeding season.

    Henrietta spent years measuring star positions and sizes from photographs taken by the telescope at the Harvard College Observatory, where she worked. After Henrietta observed that certain stars had a fixed pattern to their changes, her discovery made it possible for astronomers to measure greater and greater distances—leading to our present understanding of the vast size of the universe.An astronomer of her time called Henrietta Leavitt “one of the most important women ever to touch astronomy,” and another close associate said she had the “best mind at the Harvard Observatory.” Henrietta Leaveitt's story will inspire young women and aspiring scientists of all kinds and includes additional information about the solar system and astronomy.

    And, it's true, many of them do. But Paul Erdos never followed the usual path. At the age of four, he could ask you when you were born and then calculate the number of seconds you had been alive in his head. But he didn't learn to butter his own bread until he turned twenty. Instead, he traveled around the world, from one mathematician to the next, collaborating on an astonishing number of publications. With a simple, lyrical text and richly layered illustrations, this is a beautiful introduction to the world of math and a fascinating look at the unique character traits that made "Uncle Paul" a great man.

     In Elkhorn Slough, an inlet on the California coast, seagrass grows healthy and strong in the shallow water. This healthy seagrass baffled marine biologist Brent Hughes. The scientist expected this estuary to be overrun with algae, causing the seagrass to die. Why was the seagrass thriving? As Brent investigated, signs pointed to an unexpected player helping to keep the seagrass healthy: sea otters! What do these top predators have to do with an aquatic grass at the opposite end of the food chain? Brent's discovery gave scientists insight into the delicate balance of ecosystems.

    When she saw mustangs being rounded up and killed to make room for ranchers' livestock, she knew she had to speak up. In 1950, she began writing letters to local newspapers and politicians, defending the horses' right to raom free.Many people told Annie to hush up, but they couldn't stop her. She soon became a voice for mustangs throughout the state of Nevada, speaking on their behalf at town halls and meetings.But Annie was only one person, and she wanted to do more. So she got children to speak up, too, by having them write letters to Washington, D.C., officials to ask them to save the mustangs. Finally, with the help of her young "pencil brigade," Annie persuaded Congress to pass nationwide laws protecting wild horses and burros on public land nationwide.Readers will find inspiration in this portrait of an early animal-rights advocate, who spoke up for what she believed in, and empowered a generation of children to be a voice for the voiceless.

    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.
