The kingdom of fungi has survived all five major extinction events. They are the architects of the natural world, integral to all life. They sustain critical ecosystems, recycling nutrients and connecting plants across vast areas, and help to produce many staples of modern life, such as wine, chocolate, bread, detergent and penicillin. Today, in the face of urgent ecological, societal and spiritual crises, fungi are being engineered to grow meat alternatives, create new sources of medicine, produce sustainable biomaterials, remediate the environment and even expand our collective consciousness. The Future is Fungi is a complete introduction to this hidden kingdom. Exploring their past, present and potential future impact in four key areas - food, medicine, psychedelics and mental health, and environmental remediation - this book not only reveals how fungi have formed the foundations of modern life but how they might help shape our future. Rich with informative texts, awe-inspiring 3D digital art and tips on how to immerse yourself in the world of fungi, this is a manifesto for the future, an invitation into a deeper awareness of our relationship with the natural world, each other, and ourselves.
