What is the summary of dream birds by rob Nixon?

In Dream Birds, Rob Nixon explores how human dreams of a better future - including the dream of sustainability - have taken shape in the context of the ecological changes of the last two centuries. He considers the history of natural history and its dreams of a unified ecological order, along with the impact of colonial domination on both people and the environment, and the ways that technology has been developed to manage and control nature. He shows how a variety of dreams for the future have developed - from the utopian dream of a perfected planet to the dystopian dream of a degraded and toxic one. He also suggests that the dream of a sustainable future may be possible to achieve if we can learn from the past and present and work together to build a better world.
