Resumen
Descripción
Itis increasingly evident that approaching agricultural growth not taking the limits of ecosystems into consideration has reached critical levels of environmental impact and that costs of environmental service losses are no longer bearable (Ecosystems..., 2005; Kitzes et al., 2008). Agriculture can negatively affect the environmental balance by inefficiently using natural resources and/or by using them (water, soil and air) as receptors for pollutants and contaminants. These facts are economically defined as negative externalities because they are not taken into consideration by the markets and, therefore, their costs are not part of product prices (Dobbs; Pretty, 2004; Moss, 2008).
