You'll have to forgive the staid title: Right from the start, The Farm as Natural Habitat: Reconnecting Food Systems with Ecosystems is thoroughly Midwestern in tone -- reserved, practical, and down-to-earth. Edited by long-time sustainable-agriculture advocates Dana and Laura Jackson, a mother-daughter team, the essays collected here describe farming practices that mimic and protect natural systems. But if the voice is mild, the message is urgent: Environmentalists must build ties with farmers if we are to grow food without destroying topsoil, poisoning our air and water, and killing wildlife.
