Natural Resources for Sustainability, a Berkshire Essential, includes thirty-two articles covering the nature, extraction, and uses of today’s most important natural resources, concerns, and management approaches. In recent years, energy has become one of the most important categories of natural resource concerns, from fossil fuel to renewable and “perpetual” (e.g., solar) energy sources. Water resources are also a growing global concern, both in terms of quantity and quality. In addition to these key topics, this Berkshire Essential covers legal and economic issues, fish and fishery management, forest environments, biotic resources, the Green Revolution, and agricultural resources. The articles are drawn from the Berkshire Encyclopedia of Sustainability, written by a group of international expert authors, and edited for clarity and coherence.
