How much of our daily caloric intake comes from ingesting substances that, technically speaking, do not meet traditional definitions of “food”? Chances are, if you’re eating something that came wrapped in plastic and contains a funky ingredient you don’t have in your kitchen, it's most likely—almost definitely—ultra-processed food, or UPF.

On a winter night in 1997, a British Columbia timber scout named Grant Hadwin committed an act of shocking violence in the mythic Queen Charlotte Islands. His victim was legendary: a unique 300-year-old Sitka spruce tree, fifty metres tall and covered with luminous golden needles.

In May 2016, Fort McMurray, the hub of Canada's petroleum industry and America's biggest foreign supplier, was overrun by wildfire. The multi-billion-dollar disaster melted vehicles, turned entire neighborhoods into firebombs, and drove 88,000 people from their homes in a single afternoon. Through the lens of this apocalyptic conflagration—the wildfire equivalent of Hurricane Katrina—John Vaillant warns that this was not a unique event but a shocking preview of what we must prepare for in a hotter, more flammable world.

In Generation Dread, Britt Wray seamlessly merges scientific knowledge with emotional insight to show how these intense feelings are a healthy response to the troubled state of the world. The first crucial step toward becoming an engaged steward of the planet is connecting with our climate emotions, seeing them as a sign of humanity, and learning how to live with them. We have to face and value eco-anxiety, Wray argues, before we can conquer the deeply ingrained, widespread reactions of denial and disavowal that have led humanity to this alarming period of ecological decline.

A farm kid at heart, and a Nlaka'pamux woman of mixed ancestry, Dr. Jennifer Grenz always felt a deep connection to the land. Which is why, after nearly two decades of working as a restoration ecologist in the Pacific Northwest, she became frustrated that she and her colleagues weren't making the meaningful change needed for plant, animal and human communities to adapt to a warming climate. She began to question the central conceit of restoration ecology: that somehow, we must return the natural world to an untouched, pristine state, placing humans in a godlike role.

Thomas Homer-Dixon brings to bear his formidable understanding of the urgent problems that confront our world to clarify their scope and deep causes. The Upside of Down provides a vivid picture of the immense stresses that are simultaneously converging on our societies and threatening a breakdown that would profoundly shake civilization. It shows, too, how we can choose a better route into the future.

Weaving together family history, genetic discovery, and scenes from her life, Ami McKay tells the compelling, true-science story of her own family's unsettling legacy of hereditary cancer while exploring the challenges that come from carrying the mutation that not only killed many people you loved, but might also kill you.

For two decades, John Mighton has developed strategies for fostering intellectual potential in all children through learning math. Math, Mighton says, provides us with mental tools of incredible power. When we learn math we learn to see patterns, to think logically and systematically, to draw analogies, to perceive risk, to understand cause and effect - among many other critical skills. Yet we tolerate and in fact expect a vast performance gap in math among students and live in a world where many adults aren't equipped with these crucial tools.

Today just about everything we've known and relied on (our natural environment, economy, societies, cultures and institutions) is changing dramatically—too often for the worse. Without radical new approaches, our planet will become unrecognizable as well as poorer, more violent, more authoritarian. Thomas Homer-Dixon calls on his extraordinary knowledge of complexity science, of how societies work and can evolve, and of our capacity to handle threats, to show that we can shift human civilization onto a new path if we mobilize our minds, spirits, imaginations and collective values.

It's amazing how little can change in a decade. In 2009, a book transformed the way we see our frying pans, thermometers, and tuna sandwiches. Daily life was bathing us in countless toxins that accumulated in our tissues, were passed on to our children, and damaged our health. To expose the extent of this toxification, environmentalists Rick Smith and Bruce Lourie offered themselves to science and undertook a series of over a dozen experiments to briefly raise their personal levels of mercury, BPA, Teflon, and other pollutants.

For more than 20 years, Naomi Klein has been the foremost chronicler of the economic war waged on both people and planet - and the champion of a sweeping environmental agenda with stability and justice at its center. In lucid dispatches from the frontlines - from the ghostly Great Barrier Reef, to the annual smoke-choked skies of the Pacific Northwest, to post-hurricane Puerto Rico, to a Vatican attempting an unprecedented "ecological conversion".

Traveling in a canoe along the Yukon River with the migrating salmon, a three-month journey through untrammeled wilderness, Adam Weymouth traces the profound interconnectedness of the people and the Chinook through searing portraits of the individuals he encounters. He offers a powerful, nuanced glimpse into the erosion of indigenous culture and into our ever-complicated relationship with the natural world. Weaving in the history of the salmon run and their mysterious life cycle, Kings of the Yukon is extraordinary adventure and nature writing and social history at its most compelling.

In 2004, an enigmatic charter captain named Al Anderson caught and tagged one Atlantic bluefin tuna off New England's coast. Fourteen years later that same fish—dubbed Amelia for her ocean-spanning journeys—was caught again, this time in a Mediterranean fish trap. Over his fishing career, Al marked more than sixty thousand fish with plastic tags, an obsession that made him nearly as many enemies as it did friends. His quest landed him in the crossfire of an ongoing fight between a booming bluefin tuna industry and desperate conservation efforts.

In an astonishing, tough firsthand reportage, Chris Hedges draws on stories from inside communities across America and reveals how the hurricanes of change have allowed an array of pathologies to arise: the opioid crisis, the retreat into gambling, the corporate coup d'état of government, the pornification of culture, the rise of magical thinking, the emboldening of violence and hate, the plagues of suicides, and the global upheaval caused by catastrophic climate change.

The dovekie is a seabird the size of a child’s heart that spends its winters on the coast of Newfoundland, thriving in one of the toughest climates on Earth. The polar bear is an apex predator, designed to persevere in the Arctic's extreme conditions. The North Atlantic right whale outweighs the humpback by more than twenty tons and feeds on enormous quantities of tiny plankton in northeastern waters before migrating south for the winter. Wildlife biologist and writer Holly Hogan brings to life the wonder of these creatures and many other birds, fish and marine mammals she has encountered.
