In a collection of stories that is frequently touching, surprisingly funny and always thought-provoking, author Carrie Saxifrage seeks out the places where science meets self-discovery, inviting us to join her as she: Learns the art of appreciation from an ancient jawbone Hikes solo through the wilderness to find balance in a field of blueberries Swims for four hours through cold, open water, seeking a fleeting state of grace. Each of the stories in The Big Swim encourages possibilities for greater personal satisfaction with lower environmental impacts. While exploring significant topics, such as sustainable forestry, nature-centered philosophy or First Nations culture, the author discovers that the greatest adventure is learning to align how she lives with what she loves. By turning her own despair into action she paves the way for us all to discover the many tools we have at hand to meet the biggest challenge humanity has ever faced.
