In 1972, The Limits to Growth introduced the idea that world resources are limited. Soon after, people became aware of the threats to the world’s rainforests, the biggest terrestrial repositories of biodiversity and essential regulators of global air and water cycles. Since that time, new research and technological advances have greatly increased our knowledge of how rainforests are being affected by changing patterns of resource use. Increasing concern about climate change has made it more important than ever to understand the state of the world’s tropical forests.This book provides an up-to-date picture of the health of the world’s tropical forests. Claude Martin, an eminent scientist and conservationist, integrates information from remote imaging, ecology, and economics to explain deforestation and forest health throughout the world. He explains how urbanization, an increasingly global economy, and a worldwide demand for biofuels put new pressure on rainforest land. He examines the policies and market forces that have successfully preserved forests in some areas and discusses the economic benefits of protected areas. Using evidence from ice core records and past forest cover patterns, he predicts the most likely effects of climate change.Claude Martin brings his wealth of experience as an ecologist, director of the WWF, and advistor to various conservation organizations to bear on the latest research from around the world. Contributions from eight leading experts provide additional insight.
Where Do Camels Belong?
Where do camels belong? In the Arab world is the obvious answer. But they are relative newcomers there. They evolved and lived for tens of millions of years in North America, while today they retain their greatest diversity in South America and have their only wild populations in Australia. This is a classic example of the problems that underlie the issues of natural and invasive species, a hot issue right now, as the flip side of biodiversity. But do we need to fear invaders? And indeed, can we control them, and do we choose the right targets? In Where Do Camels Belong? Ken Thompson puts forward a fascinating array of narratives on invasive and natural plants and animals to explore what he sees as the crucial question — why only a minority of introduced species succeed, and why so few of them go on to cause trouble. He discusses, too, whether fear of invasive species could be getting in the way of conserving biodiversity, and especially of responding to the threat of climate change. This is a timely, instructive and controversial book that delivers unexpected answers.
Casting Quiet Waters
In Casting Quiet Waters, some of North America’s most respected literary writers take us on a fishing trip and use that as an opportunity to explore issues of the human condition. A little more than five centuries ago an odd English nun named Dame Juliana Berners (“The Prioress of St. Albans”) wrote the first book about fishing. Her obscure but legendary tome, a Treatysse of Fyshynge wyth an Angle, is as much a work of philosophy as a how-to manual, and in it she prescribes fishing as “a cure for domestic calamatie.” This anthology responds to her advice. A dozen of North America’s top writers embark on individual fishing trips and see if limpid water and the silence of wild places will help them reflect on their own lives and calamities. The exploratory process of writing is not so different from the process of trawling the unknown invisible world beneath the surface of a river or lake. The angler and writer both toss lines, chase shadows, and spend countless hours pondering what might have been if they’d handled that last opportunity with more gentleness and skill.
Barle's Story
When a 19-year old female polar bear named Barle is rescued from the inhumane conditions of a circus in the Caribbean and flown to safety in Detroit, zookeeper Else Poulsen — renowned throughout the world for her work rehabilitating bears who have been abused — is on hand to meet her and help her on the road to recovery and self-discovery. Thus begins Barle’s gradual introduction into the world of polar bears. Slowly she forges relationships with the other bears in the zoo and eventually mates with a young male and successfully raises a cub. By living in a caring, enriched environment focused on her welfare, Barle is able to recover from the trauma she had suffered at the circus and develop skills that are important to thriving as a polar bear. As Poulsen documents, however, not all captive bears are so fortunate. Augmented with black-and-white photographs, Barle’s Story provides a rich and moving portrait of a remarkable bear and of the author’s inspiring work to help her discover her true polar bear ways.
Planet Heart
We’ve all heard the risk factors for cardiovascular disease: high blood pressure, high cholesterol, obesity, smoking, stress, and a sedentary lifestyle. But what about our environment? Despite almost 500 recent studies that show the links between air and water quality, biodiversity, and heart health, a poor environment as a critical cardiovascular risk factor has largely been ignored. In Planet Heart, cardiologist François Reeves aims to redress this imbalance with an incisive and authoritative look at the subject. Why did North America experience an explosion of cardiovascular disease in the mid-20th century? Why are people in China, who were until recently protected from cardiovascular disease, now suffering a surge of heart attacks? Why are there more heart attacks during episodes of smog? Why would living near an urban green space halve the difference in cardiac mortality between the rich and poor? In his lively, accessible text, Reeves not only sheds light on these questions with the latest scientific evidence but also offers tangible solutions that could mean better health for our hearts and for our planet.Published in partnership with the David Suzuki Foundation

The Endangered Species Road Trip
Bill Bryson meets John Vaillant in this life list quest to see the rarest species in North America.Crammed into a minivan with wife, toddler, infant, and dog, accompanied by mounds of toys, diapers, tent, sleeping bags, and other paraphernalia, Cameron MacDonald embarks on a road trip of a lifetime to observe North America's rarest species. In California, the family camps in the brutally hot Mojave, where he observes a desert tortoise—"the size and shape of a bike helmet and the colour of gravel” sitting motionless in the shade of a scrubby sagebush. In Yellowstone, after driving through unseasonal snow, he manages to spot a rare black wolf and numerous grizzlies, which, unfortunately, call forth a crowd of «grizzly gawkers.» The journey takes the MacDonald family from British Columbia, along the west coast of the U.S., through the Southwest and Florida, up the east coast of the U.S., and finally to eastern Canada and then back home to BC.Along the way, MacDonald offers fascinating details about the natural history of the endangered species he seeks, as well as threats like overpopulation, commercial fishing, and climate change that are driving them towards extinction.
The War on Science
A passionate and meticulously researched argument against the Harper government's war on scienceIn this arresting and passionately argued indictment, award-winning journalist Chris Turner contends that Stephen Harper's attack on basic science, science communication, environmental regulations, and the environmental NGO community is the most vicious assault ever waged by a Canadian government on the fundamental principles of the Enlightenment. From the closure of Arctic research stations as oil drilling begins in the High Arctic to slashed research budgets in agriculture, dramatic changes to the nation's fisheries policy, and the muzzling of government scientists, Harper's government has effectively dismantled Canada's long-standing scientific tradition. Drawing on interviews with scientists whose work has been halted by budget cuts and their colleagues in an NGO community increasingly treated as an enemy of the state, The War on Science paints a vivid and damning portrait of a government that has abandoned environmental stewardship and severed a nation.
Fishing the River of Time
At age eighty, Tony Taylor journeys from Sydney, Australia, to British Columbia to fish the Cowichan River with his eight-year-old grandson, Ned. The trip is an opportunity for Tony to return to a landscape that has had a profound effect on his life and his way of thinking, and to share this place with his grandson. As Tony teaches Ned the patient art of fly-fishing, a lifetime of memories, thoughts, and stories unspool in peaceful reflections by the water's edge. Fishing the River of Time is an elegant meditation on nature, life, and family, written with warmth and wisdom. It inspires self-reflection and an appreciation of the natural world and the fundamentals of our human experience. It is destined to become a classic work of simple living in the mold of Henry David Thoreau's Walden.
Long Beach Wild
Each year, more than a million people visit the spectacular sweep of sand that stretches along Vancouver Island's west coast between Tofino and Ucluelet to watch waves crash ashore on a series of beaches-essentially one long beach separated by small rocky headlands, a shoreline steps away from howling wolves and towering red cedars.In Long Beach Wild: A Celebration of People and Place on Canada's Rugged Western Shore, local resident Adrienne Mason uses her intimate knowledge of the area and a selection of historic and contemporary photos to explore the region's rich natural and cultural history.Mason shows how Long Beach was shaped by many forces, including volcanoes, glaciers, and torrents of water. She describes how the deposits of gravel and silt that this tumult left behind allowed offshore kelp beds and sea otters to thrive and supported the growth of countless other organisms, from lichens and ferns to waterfowl and deer.She also describes how First Nations people found inspiration and sustenance in the area for thousands of years, hunting whales on the open ocean using harpoons with mussel-shell blades and great lengths of cedar bark rope.As well as describing the traditions of the area's First Nations, Mason
