Faith in a Seed contains the hitherto unpublished work The Dispersion of Seeds, one of Henry D. Thoreau's last important research and writing projects, and now his first new book to appear in 125 years.

With the remarkable clarity and grace that characterize all of his writings, Thoreau describes the ecological succession of plant species through seed dispersal. The Dispersion of Seeds, which draws on Charles Darwin's theory of natural selection, refutes the then widely accepted theory that some plants spring spontaneously to life, independent of roots, cuttings, or seeds. As Thoreau wrote: "Though I do not believe a plant will spring up where no seed has been, I have great faith in a seed. Convince me that you have a seed there, and I am prepared to expect wonders."

Henry D. Thoreau's Faith in a Seed, was first published in hardcover in 1993 by Island Press under the Shearwater Books imprint, which unifies scientific views of nature with humanistic ones. This important work, the first publication of Thoreau's last manuscript, is now available in paperback. Faith in a Seed contains Thoreau's last important research and writing project, The Dispersion of Seeds, along with other natural history writings from late in his life. Edited by Bradley P. Dean, professor of English at East Carolina University and editor of the Thoreau Society Bulletin, these writings demonstrate how a major American author at the height of his career succeeded in making science and literature mutually enriching.

The lavish array of organisms known as "biodiversity" is an intricately linked web that makes the earth a uniquely habitable planet. Yet pressures from human activities are destroying biodiversity at an unprecedented rate. How many species can be lost before the ecological systems that nurture life begin to break down?

In The Work of Nature, noted science writer Yvonne Baskin examines the threats posed to humans by the loss of biodiversity. She summarizes and explains key findings from the ecological sciences, highlighting examples from around the world where shifts in species have affected the provision of clean air, pure water, fertile soils, lush landscapes, and stable natural communities.

As Baskin makes clear, biodiversity is much more than number of species -- it includes the complexity, richness, and abundance of nature at all levels, from the genes carried by local populations to the layout of communities and ecosystems across the landscape. Ecologists are increasingly aware that mankind's wanton destruction of living organisms -- the planet's work force -- threatens to erode our basic life support services. With uncommon grace and eloquence, Baskin demonstrates how and why that is so.

Distilling and bringing to life the work of the world's leading ecologists, The Work of Nature is the first book of its kind to clearly explain the practical consequences of declining biodiversity on ecosystem health and function.
