An effective program of environmental education requires the identification of the knowledge that must be imparted. This paper compares the effects of human-environment system knowledge (i.e., knowledge related to environmental problems caused by humans) and environmental action knowledge (i.e., knowledge of possible courses of action to reduce human impact on the environment) on pro-environmental behavior. Environmental knowledge and pro-environmental behavior of 950 Chilean adults were assessed with a survey. Both types of knowledge were related to pro-environmental behavior (r = 0.25 and r = 0.22, respectively, p < 0.001). These results seem to contradict previous studies that found that system knowledge is not directly related to pro-environmental behavior. However, existing scales of environmental system knowledge are behavioral-distant due to their greater number of general geography knowledge items. In contrast, our human-environmental system knowledge scale focuses on understanding global environmental problems and, therefore, can be expected to relate more closely to pro-environmental behavior. To promote pro-environmental behavior, we suggest teaching more human-environment system knowledge and environmental action knowledge. Since different forms of environmental knowledge must work together in a convergent manner in order to foster pro-environmental behavior, the present study represents an important contribution by showing that greater human-environment system knowledge is correlated with pro-environmental behavior.

Environmental education programs neglect the aspect of prosocial behavior as a correlate of pro-environmental behavior. This article examines the possible benefits of increasing the emphasis on prosocial behavior as a way to reinforce environmental education. In our study, prosocial behavior was positively related to pro-environmental behavior (r = 0.34, p < 0.001), and even a combined scale consisting of prosocial and pro-environmental behavior items showed an acceptable reliability (separation reliability = 0.82, at the level of the separated scales), which implies that prosocial and pro-environmental behaviors are a similar class of behavior. We can assume that the two underlying propensities (prosocial behavior and pro-environmentalism) are probably only two facets of an overarching common propensity that supports both kinds of behavior. Therefore, promoting one facet will, through its relationship with the other facet, also foster the respective other facet. Even more so, it might be most effective to relate to both propensities equally.

Copper contamination stemming from copper-based pesticides poses a grave concern in vineyards and orchards, causing toxicity to soil organisms. Here, we present a comprehensive review of global data encompassing copper levels in these soils, c...
