Este libro que recomiendo para un mayor entendimiento de nuestro blogger habla sobre  la necesidad de una limpieza urgente en los rios contaminados ya que afecta el ecosistema, recordemos que habitan especies en los rios ya sean peces, plantas, corales que ayudan a mantener el equilibrio de nuestro sistema.

RESEÑA:

Environmental problems in coastal ecosystems can sometimes be attributed to excess

nutrients flowing from upstream watersheds into estuarine settings. This nutrient

over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef

destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient

over-enrichment, and scientists predict worsening problems in the years ahead.

Clean

Coastal Waters explains 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," the

Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains

how nutrients work in the environment, why nitrogen is important, how enrichment turns

into over-enrichment, and why some environments are especially susceptible. Economic

as well as ecological impacts are examined.

In addressing abatement strategies, the

committee discusses the importance of monitoring sites, developing useful models of

over-enrichment, and setting water quality goals. The book also reviews voluntary

programs, mandatory controls, tax incentives, and other policy options for reducing the

flow of nutrients from agricultural operations and other sources.
