Book Description
All life — whether on land or in the sea — depends on the oceans for two things: • Oxygen. Most of Earth’s oxygen is produced by phytoplankton in the sea. These humble, one-celled organisms, rather than the spectacular rain forests, are the true lungs of the planet. • Climate control. Our climate is regulated by the ocean’s currents, winds, and water-cycle activity. Sea Sick is the first book to examine the current state of the world’s oceans — the great unexamined ecological crisis of the planet — and the fact that we are altering everything about them; temperature, salinity, acidity, ice cover, volume, circulation, and, of course, the life within them. Alanna Mitchell joins the crews of leading scientists in nine of the global ocean’s hotspots to see firsthand what is really happening around the world. Whether it’s the impact of coral reef bleaching, the puzzle of the oxygen-less dead zones such as the one in the Gulf of Mexico, or the shocking implications of the changing Ph balance of the sea, Mitchell explains the science behind the story to create an engaging, accessible yet authoritative account.

Book Description
Canada's diverse landscape speaks to its fascinating geological history, from towering peaks to Prairie plains, from fertile farmlands of the Great Lakes and St. Lawrence Lowlands to rugged cliffs of the Atlantic shore. However, the modern landscape is just the latest episode in an epic story spanning more than 4 billion years. Four Billion Years and Counting unveils the geological history of Canada and makes connections between geology and social issues such as climate change, hazards such as landslides and earthquakes, and other environmental factors. The text features contributions from some 100 specialists, and is richly illustrated with over 500 colour photographs and diagrams. Four Billion Years and Counting is a fascinating exploration of Canada's geology for those who are intrigued by the landscape and the vital connection between ourselves and what lies beneath our feet.

Book Description
The discovery of insulin at the University of Toronto in 1921-22 was one of the most dramatic events in the history of the treatment of disease. Insulin was a wonder-drug with ability to bring patients back from the very brink of death, and it was no surprise that in 1923 the Nobel Prize for Medicine was awarded to its discoverers, the Canadian research team of Banting, Best, Collip, and Macleod. In this engaging and award-winning account, historian Michael Bliss recounts the fascinating story behind the discovery of insulin – a story as much filled with fiery confrontation and intense competition as medical dedication and scientific genius. Originally published in 1982 and updated in 1996, The Discovery of Insulin has won the City of Toronto Book Award, the Jason Hannah Medal of the Royal Society of Canada, and the William H. Welch Medal of the American Association for the History of Medicine.

Book Description
The mystery of Earth's invisible, life-supporting power Alanna Mitchell's globe-trotting history of the science of electromagnetism and the Earth's magnetic field--right up to the latest indications that the North and South Poles may soon reverse, with apocalyptic results--will soon change the way you think about our planet. Award-winning journalist Alanna Mitchell's science storytelling introduce intriguing characters--from the thirteenth-century French investigations into magnetism and the Victorian-era discover that electricity and magnetism emerge from the same fundamental force to the latest research. No one has ever told so eloquently how the Earth itself came to be seen as a magnet, spinning in space with two poles, and that those poles have dramatically reversed many time, often coinciding with mass extinctions. The most recent reversal was 780,000 years ago. Mitchell explores indications that the Earth's magnetic force field is decaying faster than previously thought. When the poles switch, a process that takes many years, the Earth is unprotected from solar radiation storms that would, among other disturbances, wipe out much and possible all of our electromagnetic technology. Navigation for all kinds of animals is disrupted without a stable, magnetic North Pole. But can you imagine no satellites, no Internet, no smartphones--maybe no power grids at all? Alanna Mitchell offers a beautifully crafted narrative history of surprising ideas and science, illuminating invisible parts of our own planet that are constantly changing around us.
