Bears and bureaucrats, timber and telephone lines, poaching and predators, fires and families – all these play a part in this fascinating study of Canada’s National Park wardens. The warden service has been integral to Canada’s National Parks from their earliest days. First established in Rocky Mountains Park (now Banff National Park) in 1909, the position of Fire and Game Guardian was the precursor of today’s National Park warden, whose duties now include resource management, law enforcement, and public safety.
Sustainable development is the key for the survival in 21st century. The natural resources are finite and cannot be used with impunity because we are the custodian of these resources and have responsibility to pass these to the next generation. This monumental task requires several major commitments and most important of them is to arrest population explosion which has already reached seven billion.
This revolutionary book is a practical guide for helping communities in any location or context – from a fishing community in England to a logging town in Canada to a farming village in India – to develop a collective vision of a prosperous and sustainable future and a road-map for mobilizing and managing their natural resources to realize that future.

This book provides a comprehensive treatment of the chemical nature of the Earth’s early surface environment and how that led to the origin of life. This includes a detailed discussion of the likely process by which life emerged using as much quantitative information as possible. The emergence of life and the prior surface conditions of the Earth have implications for the evolution of Earth’s surface environment over the following 2-2.5 billion years. The last part of the book discusses how these changes took place and the evidence from the geologic record that supports this particular version of early and evolving conditions.
Restoring Layered Landscapes brings together historians, geographers, philosophers, and interdisciplinary scholars to explore ecological restoration in landscapes with complex histories shaped by ongoing interactions between humans and nature. For many decades, ecological restoration – particularly in the United States – focused on returning degraded sites to conditions that prevailed prior to human influence. This model has been broadened in recent decades, and restoration now increasingly focuses on the recovery of ecological functions and processes rather than on returning a site to a specific historical state.
In this remarkable book, Barbara Freese takes us on a rich historical journey that begins hundreds of millions of years ago and spans the globe. Prized as the best stone in Britain by Roman invaders who carved jewelry out of it, coal has transformed societies, launched empires, and expanded frontiers. It made China an eleventh-century superpower, inspired the "Communist Manifesto," and helped the North win the American Civil War. Yet coal s transformative power has come at tremendous cost, from the blackening of our lungs and skies, to the perils of mining, to global warming.
