商品簡介
This report explains the technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "dead zone" and other cases, it explains how human activity has fundamentally changed nutrient availability, how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. It also addresses economic and ecological impacts, abatement strategies, and policy options. Annotation c. Book News, Inc., Portland, OR (booknews.com)
