Summary: In the Amazon Basin the greatest violence sometimes begins as a flicker of light beyond the horizon. There in the perfect bowl of the night sky, untouched by light from any human source, a thunderstorm sends its premonitory signal and begins a slow journey to the observer, who thinks: the world is about to change. Watching from the edge of the Brazilian rain forest, witness to the sort of violence nature visits upon its creatures, Edward O. Wilson reflects on the more crucible of evolution, and so begins his remarkable account of how the living world became diverse and how humans are destroying that diversity. Wilson, internationally regarded as the dean of biodiversity studies, conducts us on a tour through time, traces the processes that create new species in bursts of adaptive radiation, and points out the cataclysmic events that have disrupted evolution and diminished global diversity over the past 600 million years. The five enormous natural blows to the planet (such as meteorite strikes and climatic changes) required 10 to 100 million years of evolutionary repair. The sixth great spasm of extinction on earth - caused this time entirely by humans - may be the one that breaks the crucible of life. Wilson identifies this crisis in countless ecosystems around the globe: coral reefs, grasslands, rain forests, and other natural habitats. Drawing on a variety of examples such as the decline of bird populations in the United States, the extinction of many species of freshwater fish in Africa and Asia, and the rapid disappearance of flora and fauna as the rain forests are cut down, he poignantly describes the death throes of the living worlds diversity - projected to decline as much as 20 percent by the year 2020. All evidence marshaled here resonates through Wilson's tightly reasoned call for a spirit of stewardship over the worlds biological wealth. He makes a plea for specific actions that will enhance rather than diminish not just diversity but the quality of life. Harvard Professor and two-time Pulitzer Prize winner Edward Wilson takes readers through time -- tracing the processes that create new species, the five cataclysmic events that have disrupted evolution over the past 600 million years, and how humans are destroying diversity at a projected rate of 20 percent over the next 30 years. This book "examines organic history in terms of reproductive isolation, nucleotide variation (microevolution) and adaptive radiation (macroevolution).Wilson focuses on the abundance of life forms within tropical rain forests, especially pointing out that both vanishing species and their threatened natural habitats (hot spots) must be saved if we are to maintain the earth's rich and needed genetic reservoir."
