In Butterflies: Ecology and Evolution Taking Flight, the world's leading experts synthesize current knowledge of butterflies to show how the study of these fascinating creatures as model systems can lead to deeper understanding of ecological and evolutionary patterns and processes in general. The twenty-six chapters are organized into broad functional areas, covering the uses of butterflies in the study of behavior, ecology, genetics and evolution, systematics, and conservation biology. Especially in the context of the current biodiversity crisis, this book shows how results found with butterflies can help us understand large, rapid changes in the world we share with them—for example, geographic distributions of some butterflies have begun to shift in response to global warming, giving early evidence of climate change that scientists, politicians, and citizens alike should heed.

The first international synthesis of butterfly biology in two decades, Butterflies: Ecology and Evolution Taking Flight offers students, scientists, and amateur naturalists a concise overview of the latest developments in the field. Furthermore, it articulates an exciting new perspective of the whole group of approximately 15,000 species of butterflies as a comprehensive model system for all the sciences concerned with biodiversity and its preservation.

Hope on Earth is the thought-provoking result of a lively and wide-ranging conversation between two of the world’s leading interdisciplinary environmental scientists: Paul R. Ehrlich, whose book The Population Bomb shook the world in 1968 (and continues to shake it), and Michael Charles Tobias, whose over 40 books and 150 films have been read and/or viewed throughout the world.  Hope on Earth offers a rare opportunity to listen in as these deeply knowledgeable and highly creative thinkers offer their takes on the most pressing environmental concerns of the moment.

Both Ehrlich and Tobias argue that we are on the verge of environmental catastrophe, as the human population continues to grow without restraint and without significant attempts to deal with overconsumption and the vast depletion of resources and climate problems it creates. Though their views are sympathetic, they differ in their approach and in some key moral stances, giving rise to a heated and engaging dialogue that opens up dozens of new avenues of exploration.  They both believe that the impact of a human society on its environment is the direct result of its population size, and through their dialogue they break down the complex social problems that are wrapped up in this idea and attempts to overcome it, hitting firmly upon many controversial topics such as circumcision, religion, reproduction, abortion, animal rights, diet, and gun control.  For Ehrlich and Tobias, ethics involve not only how we treat other people directly, but how we treat them and other organisms indirectly through our effects on the environment.  University of California, Berkeley professor John Harte joins the duo for part of the conversation, and his substantial expertise on energy and climate change adds a crucial perspective to the discussion of the impact of population on global warming.

This engaging and timely book invites readers into an intimate conversation with some of the most eminent voices in science as they offer a powerful and approachable argument that the ethical and scientific issues involved in solving our environmental crisis are deeply intertwined, while offering us an optimistic way forward. Hope on Earth is indeed a conversation we should all be having.

Though separated by thousands of miles, the United States and Australia have much in common. Geographically both countries are expansive—the United States is the fourth largest in land mass and Australia the sixth—and both possess a vast amount of natural biodiversity. At the same time, both nations are on a crash course toward environmental destruction. Highly developed super consumers with enormous energy footprints and high rates of greenhouse-gas emissions, they are two of the biggest drivers of climate change per capita. As renowned ecologists Corey J. A. Bradshaw and Paul R. Ehrlich make clear in Killing the Koala and Poisoning the Prairie, both of these countries must confront the urgent question of how to stem this devastation and turn back from the brink.
 
In this book, Bradshaw and Ehrlich provide a spirited exploration of the ways in which the United States and Australia can learn from their shared problems and combine their most successful solutions in order to find and develop new resources, lower energy consumption and waste, and grapple with the dynamic effects of climate change. Peppering the book with humor, irreverence, and extensive scientific knowledge, the authors examine how residents of both countries have irrevocably altered their natural environments, detailing the most pressing ecological issues of our time, including the continuing resource depletion caused by overpopulation. They then turn their discussion to the politics behind the failures of environmental policies in both nations and offer a blueprint for what must be dramatically changed to prevent worsening the environmental crisis.
 
Although focused on two nations, Killing the Koala and Poisoning the Prairie clearly has global implications—the problems facing the United States and Australia are not theirs alone, and the solutions to come will benefit by being crafted in coalition. This book provides a vital opportunity to learn from both countries’ leading environmental thinkers and to heed their call for a way forward together.
