economics can function as a great unifier.
Ramensky  showed the real possibility of using the ecological
properties of plants for determining the expressivity of abiotic factors.
justice: The civilization of a society needs to be just to be reflected by justice.
2 Methods of Ecological
Green Equivalent Calculation and Ecosystem Analysis
The two types of external validity are: (a) population validity--the extent to which study results from a specific sample can be applied to larger similar groups, and (b) ecological
validity-the extent to which an experimental design can be generalized to a set of environmental conditions or contexts (Brewer, 2000).
The following nine case studies of harvesting and management of widely differing NTFPs illustrate clearly that to assess ecological
sustainability we need studies that seriously address the specifics of the harvesting of NTFPs and the ecological
system that supports its production, and that this may require long-term and resource-intensive studies.
Advocates for ecological
literacy suggest place-based learning as effective pedagogical theory because it is adaptive to each particular location's own wealth of unique cultural, ecological
and social characteristics (Monaghan & Curthoys, 2008).
In the face of this, it has been argued that the promotion of ecological
citizenship should be approached together with the ecological
transformation of the state (Barry, 2006, 1999; Eckersley, 2004; Christoff, 2005, 1996).
Drawing on the lessons of actual restoration projects such as Chicago Wilderness, Common Ground Relief, and Vermont Family Forests, the book successfully presents a clear introduction to important theories and activities of ecological
thought', Morton writes 'is the thinking of interconnectedness in the fullest and deepest sense' (p7).
Boons insists that the ecological
impact of any product depends on the human practices that accompany its production and consumption (the way in which ecological
impact of production and consumption activities is perceived plays a central role in how firms deal with this impact).
figures come from the Global Footprint Network and measure resource consumption and waste produced by a country in comparison to its carrying capacity as expressed in locally available resources such as agricultural land and energy.
