The extinction of biodiversity is recognized as an environmental problem in Chile. This recognition comes from both environmentalists and wildlife biologists. However, their evaluations about the conservation status of the biota are strikingly different, depicting opposite views regarding it within administrative regions of Chile, Those regions where the threats to the native biota are considered of lower importance by environmentalists are precisely the regions where wildlife biologists detect the higher numbers of threatened species and viceversa. This discrepancy demonstrates that different perceptions of the natural sourroundings may occur not only between different social groups but also within alike groups.
