This collection of 19 articles discusses the impact of changes in Aotearoa New Zealand's natural environment due to factors such as climate change, pollution and degredation of waterways and land, pest control and environmental management policy. It highlights Maori perspectives on these issues and actions that Maori have taken to maintain and restore the environment. These contributions demonstrate that the relationship that Maori have with the environment through kaitiakitanga has sound environmental principles and provide a reminder of obligations for future generations of all New Zealanders. With local, regional and central government decisions about the environment continuing to be based on a least expensive option rather than on the most sustainable, the book suggests that Maori should take a lead role as active kaitiaki to promote sound principles in the wider community for the benefit of all.
