The deteriorating state of the environment and global warming pose a serious and unprecedented threat to humanity. Yet, public response and personal behavior do not reflect the proportions of such a threat. In the present research we explored possible reasons for this discrepancy. Past research has shown that people perceive events as more threatening based on their immediacy, certainty, or personal implications. Liberman and Trope (2008) developed the concept of “psychological distance” (PD), according to which more immediate events are seen as “closer in time,” more certain events as “closer in probability,” and events with greater potential for personal harm as “socially closer.” Adopting this concept, we examined how distant, in terms of PD, people perceive environmental threats to be. Using a structural equations model, we measured how PD influences environmental threat perception. In a sample of 305 Israeli students who completed a computerized questionnaire, we found that environmental threats were perceived as psychologically distant in all of the PD dimensions, and that PD strongly affected perceived severity of environmental threats and willingness to engage in pro-environmental behavior. The reasons for the psychological remoteness of environmental threats and possible approaches to cope with its implications are discussed.

Higher education institutions are major trip-generating locations and the transportation to and from them has negative environmental influences. To discourage car owners from solo driving and encourage them to use more environmentally friendly travel modes, it is important to understand what factors influence their travel mode choice. Using a discrete choice model, we examined the motivations to leave the car at home, with and without parking fee. Besides parking fees, we examined the effects of other variables known to predict commuting choice, such as time and social discomfort, pro-environmental attitudes, reduced vehicle maintenance expenses and awareness of alternative commuting options. Results show that adding a parking fee not only increased the tendency to leave the car at home, it also influenced the relative weight given to the considerations that determine to leave the car at home. Specifically, after the introduction of a parking fee, the previously significant impacts of pro-environmental attitudes and social discomfort on leaving the car at home became non-significant, and the impacts of other, more instrumental factors (e.g., time discomfort, costs related to car ownership and maintenance, time wasted searching for a parking space and in traffic jams) which were insignificant beforehand, became the significant predictors. Parking fees were found to be effective and can change to accommodate different policies (revenue collection, pollution reduction, and students’ discomfort). The implications of such a study are the trade-off between monetary (parking fee) and non-monetary variables to accommodate more sustainable traffic management.

Developed understanding of environmental problems, consequences, and risks constitutes a core target of environmental education (EE). Ecological risks (ERs) are inherently complex, interconnected, and subject to perceptual biases. To explore whether an exposure to EE in academia improves ER literacy, we compared ER perception of students who were exposed to EE (“EE majors”) with students who were not (“non-EE majors”) Drawing on the psychometric paradigm from risk perception research, we compared ER perception between the two groups to identify whether the students perceive, appraise, and prioritize ERs differently, and whether they provide different reasons for their decisions and evaluations. We found significant differences in the perception of overall severity of environmental problems, especially of the less “popular” and familiar ones, characterized by global, complex, and extensive consequences. Compared to non-EE majors, EE majors perceived most ERs as more certain, personal, and temporally and spatially close. Risk prioritization and the reasons given for these choices also differed; EE major students’ choices were mostly guided by holistic reasons, whereas the non-EE major students’ explanations were more anthropocentric or one-dimensional. The discussion focused on the importance of ER literacy in reducing misconceptions of environmental problems and on developing an informed assessment of their severity.

There are many endangered species that are not popular, but whose conservation is, nonetheless, important. The present study deals with sharks who suffer from demonization and, accordingly, from public indifference to the deteriorating state of their conservation. We used the seasonal appearance of sharks in the Israeli coastal zone to study public perceptions and attitudes towards sharks prior to (‘control group’) and after (‘visitors’) shark watching during a visit in an information centre. We found that the shark’s image was significantly more positive among the visitors compared to the control group. We also found that visiting the information centre was strongly related to a more positive shark image and more positive attitudes toward shark conservation and willingness to act to preserve them.

Studying perceptions of litter and littering behavior among marginalized, poor and undeveloped communities is important since these populations frequently inhabit important conservation sites. Jisr-A-Zarqa ("Jisr"), is a coastal town on the Mediterranean shores of Israel and one of Israel’s poorest, densely populated communities. Litter accumulation in the streets and beach of Jisr is a known problem, and its proximity to the nearby stream and beach makes the study of littering important for the conservation of the coastal and marine habitats. I studied residents’ perceptions of litter and littering practices and found that littering and waste accumulation are surface indicators of profound underlying social, economic and political constraints, problems and distresses. These must be considered as an integrated context and addressed when designing litter-reducing interventions.
