The earth is continuously changing and evolving yet it is unclear how environmental changes will affect us in years to come. What changes are inevitable? What changes, if any, are beneficial? And what can we do as citizens of this planet to protect it and our future generations? Larry Slobodkin, one of the leading pioneers of modern ecology, offers compelling answers to these questions in . He provides many insights into ecology and the processes that keep the world functioning. This important guide introduces observations that underlie arguments about all aspects of the natural environment—including both global and local issues. To clarify difficult concepts, Slobodkin uses lake, ocean, and terrestrial ecosystems to explain ecological energy flows and relationships on a global scale. The book presents a clear and current understanding of the ecological world, and how individual citizens can participate in practical decisions on ecological issues. It tackles such issues as global warming, ecology and health, organic farming, species extinction and adaptation, and endangered species. An excellent introduction and overview, helps us to understand what steps we as humans can take to keep our planet habitable for generations to come. "This beautifully written book brings together careful observation, personal reflection, and theoretical understanding to explain the major environmental problems that confront us. Dr. Slobodkin's superb and sweeping work invites us to contemplate a great many facts and a few large values to motivate a clear and compelling response to losses of biodiversity, the problem of invasive species, global warming, and other environmental concerns."—Mark Sagoff,
