Chemical World: Science in Our Daily Lives explores some of the materials—all of which are made of basic chemical elements—that humans use or come into contact with in their day-to-day lives. Some of these chemicals are naturally occurring—clay, mercury, lead. Others have been synthesized by chemists during the past 150 years and used in a bewildering array of products ranging from roof shingles to toothpaste. Many chemical inventions, as well as naturally produced chemicals, have had profound effects on food supply, developing medicines and creating hosts of useful items for modern life. Despite people using both natural and synthetic chemicals with (mainly) good intentions, some chemicals have had unintended negative consequences. Chemical residues have contaminated ecosystems the world over and are compromising the health of many ecosystems, animals and humans. The goal of Chemical World: Science in our Daily Lives is to introduce readers to basic chemistry and chemical history, and to show how chemicals are used for particular reasons but sometimes turn out to be harmful to environmental and human health. It invites readers to take a look at the world around them and ask questions about what’s in their environment and how the things they use and eat every day can affect their own health and the planet’s health.
Going wild. We don't see it as a good thing. And why would we? For most of our time on earth, humanity has been running from lions and other wilderness dangers. We've worked hard to make our local landscapes as safe and convenient as possible. Sometimes that's meant paving over areas that might burst into weeds. Other times, we've dammed rivers for electricity or irrigation. But now pollution, climate change and disruptions to the water cycle are affecting the world in ways we never anticipated. What if the new key to making our lives safer (and even healthier) is to allow the wilderness back into our cities?
Extensively illustrated with Ian McAllister's magnificent photographs, The Salmon Bears explores the delicate balance that exists between the grizzly, black and spirit bears and their natural environment, the last great wilderness along the central coast of British Columbia. Key to this relationship are the salmon that are born in the rivers each spring, who then go out to sea as juveniles and return as adults to spawn and die, completing a cycle of life that ensures the survival of not only their own species but also virtually every other plant and animal in the rainforest. In clear language suitable for young readers, the authors describe the day-to-day activities that define the lives of these bears through the four seasons. But this is also very much the story of the Great Bear Rainforesta vast tract of land that stretches from the northern tip of Vancouver Island to the Alaska border and contains some of the largest stands of old-growth forest left on the West Coast. The Salmon Bears focuses on the interconnectedness of all life in the rainforest and makes a strong case for the importance of protecting this vital ecological resource.
The Sea Wolves sets out to disprove the notion of "the Big Bad Wolf," especially as it is applied to coastal wolvesa unique strain of wolf that lives in the rainforest along the Pacific coast of Canada. Genetically distinct from their inland cousins and from wolves in any other part of the world, coastal wolves can swim like otters and fish like the bears with whom they share the rainforest. Smaller than the gray wolves that live on the other side of the Coast Mountains, these wolves are highly social and fiercely intelligent creatures. Living in the isolated wilderness of the Great Bear Rainforest, coastal wolves have also enjoyed a unique relationship with man. The First Nations people, who have shared their territory for thousands of years, do not see them as a nuisance species but instead have long offered the wolf a place of respect and admiration within their culture. Illustrated with almost one hundred of Ian McAllister's magnificent photographs, The Sea Wolves presents a strong case for the importance of preserving the Great Bear Rainforest for the wolves, the bears and the other unique creatures that live there.

Josie is fascinated with the secrets of the prehistoric world. She and her grandfather, an amateur paleontologist, explore the beaches and cliffs near Stone Trees Cottage in Nova Scotia. Tiny bones have been discovered, but what are they from? As Josie searches for the answer, she is forced to cope with an accident and competition from an unpleasant neighbor. Time is of the essence, for she must find the answer before someone else does and before the tides and waves that exposed the secret wash it away forever.
