Generation Z, a cohort defined by digital connectivity, sensitivity to social influence, and environmental awareness, has attracted considerable scholarly attention in sustainable consumption research. Yet a persistent gap between their expressed pro-sustainability attitudes and actual purchasing decisions remains well-documented. This study examines whether Gen Z characteristics help bridge that gap by directly influencing sustainable purchase behavior and by moderating the role of purchase intention in that process. A quantitative design was employed using survey responses from 302 Gen Z consumers. The findings suggest that while Gen Z characteristics significantly predicted actual sustainable purchasing and purchase intention exerted a positive direct effect, the interaction between the two was negative and statistically significant. Conditional effects analysis further revealed that the influence of generational characteristics on purchasing behavior is stronger at lower levels of purchase intention and progressively weaker as intention increases. These results suggest that traits such as digital responsiveness, social embeddedness, and environmental orientation do not merely reinforce existing intentions but appear to compensate for their absence, activating sustainability-aligned behavior even when motivational commitment is limited. The study repositions the intention–behavior gap among Gen Z as something modulated by generational characteristics that drive purchasing behavior when intention alone falls short. Full article

This article advances a transdisciplinary framework for planetary health education grounded in multispecies responsibility and Indigenous relational ontologies. Addressing the limitations of anthropocentric environmental paradigms, the paper proposes an expanded Stratified Relational Responsibility Model integrating ethical, ecological, and neurobiological dimensions of human–more-than-human relations. The framework bridges insights from environmental ethics, anthropology, and affective neuroscience to examine how relational awareness, emotional regulation, and embodied cognition shape pro-environmental behavior. Four pedagogical pillars are introduced to support behavioral transformation, emphasizing relational perception, affective attunement, ethical reflexivity, and collective responsibility. The article further discusses implementation challenges within Western educational contexts and highlights the need for culturally responsive adaptation. By situating human agency within multispecies networks, the model contributes to ongoing debates in planetary health and sustainability education, offering a theoretically robust and practically oriented approach to fostering ecological responsibility.

The interaction between airborne allergens and environmental microplastics is an emerging concern in the context of increasing plastic pollution and allergic disease prevalence. In this study, we investigated the molecular interaction between Cry j 1, the major allergen of Japanese cedar (Cryptomeria japonica) pollen, and polyethylene terephthalate (PET) microplastic surfaces using all-atom molecular dynamics simulations integrated with computational epitope selection analyses. The simulations showed that Cry j 1 adsorbs onto PET primarily through hydrophobic and van der Waals interactions, with residues Pro165, Ala227, Tyr228, and Val163 contributing prominently to surface association. Mapping of selected epitope regions indicated that several linear B-cell epitopes remained solvent exposed following adsorption, whereas two CD4⁺ T-cell epitope regions (T5 and T6) contributed more directly to PET interaction. PET adsorption was accompanied by moderate changes in conformational dynamics, including reduced residue-level flexibility and localized secondary-structure adjustments, while the overall protein fold remained structurally stable throughout the simulation. Small decreases in radius of gyration and solvent-accessible surface area suggested mild adsorption-associated compaction rather than major unfolding. These findings indicate that PET association can influence the structural dynamics and interfacial behavior of Cry j 1 without extensive disruption of its global architecture. Because the study is entirely computational, the immunological implications remain hypothetical and require experimental validation. Nevertheless, this work provides a molecular-level framework for understanding how airborne microplastics may influence allergen behavior and protein-surface interactions in polluted atmospheric environments.

Human behavior drives environmental degradation, yet research often neglects the intergenerational dimensions of pro-environmental decisions. Individuals frequently discount future generations’ needs due to power asymmetries, lack of reciprocity, and psychological distance, thereby exacerbating the tragedy of the commons. To address this intergenerational dilemma, this research investigates the roles of psychological ownership of nature and legacy motivation across two studies. The findings reveal that both constructs significantly promote intergenerational pro-environmental decision-making. Specifically, individuals with a stronger psychological connection to nature and higher impact legacy motivation are more likely to prioritize long-term environmental sustainability. Furthermore, impact legacy motivation mediates the effect of psychological ownership of nature on these decisions. Cultivating a sense of ownership over nature catalyzes a desire to leave a tangible positive impact, which subsequently drives sustainable choices. By translating environmental attachment into intergenerational responsibility, this study provides a robust empirical psychological foundation for policies aimed at fostering individual-level sustainable behaviors for future generations.

Non-consumptive wildlife tourism serves as a vital vehicle for promoting ecological conservation and nature education. Understanding visitors’ perceptions of wildlife behavior and how these perceptions translate into long-term pro-environmental behavioral intentions is crucial for balancing visitor recreational experiences with ecological management in nature reserves. This study developed a hybrid analytical method integrating Latent Dirichlet Allocation (LDA) and Structural Equation Modeling (SEM). Based on 62,557 online reviews and 351 questionnaires collected from 33 macaque tourism sites in China, we identified three dimensions of perceived macaque behavior: food-driven approach (FDA), co-presence experience (CPE), and natural habitat-based behavior (NHB). SEM results revealed that all three dimensions significantly influenced Perceived Ecological Value (PEV) and Positive Emotional Arousal (PEA). NHB and FDA exert a stronger influence on PEV, while CPE primarily drives PEA. Furthermore, both PEV and PEA significantly promote PEBI, with PEV having a stronger effect. These findings indicate that PEBI formation relies more heavily on understanding ecological significance than on immediate positive emotions alone. These findings refine the “experience-to-conservation support” mechanism and suggest that managers should optimize ecological interpretation and regulate food interactions to foster sustainable wildlife tourism.

The Earth’s ecosystems are rapidly deteriorating due to human activities. Habitats are being lost or degraded, and associated wildlife species are declining or becoming extinct at unprecedented rates. The study area, the prefectures of Rodopi and Evros, is a Greek biodiversity hotspot containing degraded habitats, such as forests and wetlands, that are critical for many threatened wildlife species. This situation calls for conserving threatened wildlife habitats, which requires considerable funds. A structured questionnaire was used to evaluate willingness to pay (WTP) for wildlife habitat conservation. We conducted personal interviews with residents of the study area, using a sample of 849 citizens from the two regions determined through stratified random sampling design, with equal allocation to the strata. The mean annual WTP per household was estimated at EUR 21.3, yielding a total of EUR 790,000 from households in the study area. Pro-environmental behavior was positively associated with WTP. Females and those with higher household income reported higher WTP than males and those with lower household income. Government agencies were preferred over hunting clubs and environmental NGOs for implementing programs to conserve local wildlife habitats. Findings will be most useful if incorporated into policies to (a) secure the funds necessary to implement wildlife habitat conservation programs in the area and (b) increase transparency and trust between conservation entities and the local community.

Second-hand clothing is increasingly promoted as a sustainable alternative to reduce the fashion industry’s environmental impact, yet evidence on why consumers purchase second-hand apparel remains fragmented across disciplines. This literature review synthesizes prior research to identify the main motivational drivers and inhibitors of second-hand clothing purchasing and to translate them into a coherent conceptual explanation. We reviewed and conceptually integrated the academic literature on second-hand apparel consumption, focusing on how studies define, operationalize, and relate sustainability concerns, economic value, uniqueness and identity motives, and socio-cultural influences to purchase intention and behavior. The reviewed evidence indicates that pro-environmental values often coexist with utilitarian and symbolic motives, while barriers frequently involve perceived risk (e.g., quality and hygiene), effort, and access constraints. Building on this synthesis, we propose an integrative model that organizes key antecedents and mechanisms leading to purchase intention and repeat purchasing, highlighting enabling conditions and boundary factors that may strengthen or weaken these relationships. This review consolidates dispersed findings, clarifies theoretical gaps, and provides a testable framework to guide future empirical research and managerial interventions aimed at scaling circular fashion adoption.

There is often a disconnect between what university students know and believe about climate change and their level of engagement in meaningful, pro-environmental practices. The purpose of this research is to evaluate the climate change knowledge and behaviors of undergraduate students, compared to state and national respondents and to recognize existing and potential support for supporting engagement in climate change mitigating behaviors. A survey instrument aligned to the Yale Program on Climate Change Communication (YPCCC) Opinion Maps was administered to 1032 undergraduate students at Kean University in New Jersey. Odds ratio analysis suggests the likelihood of students to respond to statements regarding knowledge, risk perceptions, policy support, and behaviors, compared to surveyed populations in New Jersey and the United States. Results indicate that Kean University students are (1) knowledgeable about climate change, (2) express strong concern and policy support, and (3) regularly engage in accessible, low-barrier actions, yet are less frequently involved in less readily accessible, high-barrier actions. Interpreting these patterns through Self-determination Theory, we suggest that students’ basic psychological needs for autonomy, competence, and relatedness are more fully supported for individual engagement than for collective forms of engagement and discuss campus initiatives that may sustain meaningful climate engagement.

Environmental sustainability is crucial for human survival and the future of new generations. Anticipating regret can influence decision-making and promote sustainable behaviors. This study examines the effect of anticipated regret on pro-environmental behaviors among young adults (18–30) using regret-based short videos called “EkoToks.” A total of 128 participants were randomly assigned to an experimental group, receiving regret-evoking videos, or a control group, receiving informational videos. Pro-environmental behaviors were measured at baseline, post-test, and at three-month follow-up. Results showed significant short-term improvements in the experimental group compared to the control group, with higher scores in total pro-environmental behavior, prosocial behavior, reuse, recycling, and pro-environmental actions. At follow-up, the experimental group continued to outperform the control group in terms of total behavior, prosocial behavior, recycling, reuse, pro-environmental actions, and waste reduction. Regression analyses revealed that post-test regret significantly predicted further improvements at follow-up (compared to post-test) in total behavior, prosocial behavior, reuse, and pro-environmental actions. These findings highlight the effectiveness of anticipated regret in improving environmental behaviors, particularly low-cost ones. Full article

Spaceflight exposes astronauts to multiple environmental stressors that promote oxidative stress, including ionizing radiation, microgravity, circadian rhythm disruption, and psychological stress. These factors increase the production of reactive oxygen species (ROS) and disturb redox homeostasis, potentially affecting multiple physiological systems during long-duration missions. In addition to environmental challenges, nutritional factors may further influence oxidative balance in space. Space food systems rely on long-term storage and processing, which can lead to degradation of antioxidant nutrients and alterations in dietary composition. Furthermore, spaceflight conditions may modify eating behaviors and disrupt gut microbiome composition, both of which are closely linked to host redox regulation. This review examines current knowledge on oxidative stress during spaceflight and discusses how space food systems, dietary composition, and microbiome alterations interact with spaceflight stressors to influence redox homeostasis. Potential strategies to mitigate oxidative stress are also discussed, including preservation of antioxidant nutrients, optimization of dietary composition, reduction in pro-oxidant exposures, and microbiome-targeted approaches to support astronaut health during long-duration missions.

Background: The consumption of meat and high-fat foods is constantly discussed, with attention to their health and environmental consequences, as well as the barriers to changing current behaviors. Objective: The study aimed to examine how pro-environmental behavior, perceived food insecurity, and financial constraints correlate with intentions to limit meat and fat consumption among older adults. Methods: A cross-sectional study was conducted in 2025 among 475 individuals aged 60 to 92 years. The questionnaire includes scales that enable the calculation of four scores: Meat Reduction, Low Fat, Perceived Food Insecurity, and Lack of Financial Support. Additionally, questions about involvement in pro-ecological behaviors and sociodemographic characteristics were included. Logistic regression analysis was used to examine associations between perceived food insecurity, lack of financial support, and pro-environmental behaviors (independent variables) and intentions to reduce meat (Model 1) and fat (Model 2) (dependent variables). Results: Intentions to limit meat correlated positively with buying food produced in an environmentally friendly way (adjusted OR = 2.05; 95% CI: 1.56, 2.69), not wasting food (adjusted OR = 1.26; 95% CI: 1.05, 1.51), and buying local food (adjusted OR = 1.48; 95% CI: 1.21, 1.82). Intentions to limit fat correlated positively with buying food produced in an environmentally friendly way (adjusted OR = 1.66; 95% CI: 1.27, 2.18) and not wasting food (adjusted OR = 1.45; 95% CI: 1.20, 1.76). No relationships were found between the lack of financial support and intentions to limit meat (p = 0.069) and fat (p = 0.600). The perceived food insecurity decreased the likelihood of intentions to restrict fat (adjusted OR = 0.45; 95% CI: 0.24, 0.83), but not meat (p = 0.387). Conclusions: To better understand why experienced financial constraints did not influence the intention to reduce consumption of meat and high-fat products, further research is needed that focuses on motivation to change and the ability to change behavior among older people. Nevertheless, the results suggest that enhancing pro-environmental behaviors beyond those directly related to meat and fat consumption may facilitate reductions in meat and fat consumption through pro-environmental behavioral spillover.

Organizations are increasingly required to promote a culture of sustainability among their employees. Accordingly, a growing number of organizations have implemented work practices centered on pro-environmental behaviors. However, the psychological mechanisms underlying these behaviors in the workplace remain insufficiently explored. Grounded in Social Cognitive Theory and normative frameworks, the present study proposes a moderated mediation model examining the relationship between collective efficacy and employees’ pro-environmental behaviors, the mediating role of personal norm, and the moderating role of injunctive norm. Data were collected from 906 Italian employees who completed an online questionnaire, and the hypothesized model was tested using moderated mediation analyses. The results showed that collective efficacy was positively associated with personal norm, which in turn was positively related to pro-environmental behaviors, indicating an indirect association pattern consistent with the hypothesized mediating role of personal norm. Moreover, injunctive norm strengthened the relationship between collective efficacy and pro-environmental behaviors. These findings highlight the central role of moral obligation in translating collective beliefs into sustainable action and underscore the importance of normative organizational climates. This study contributes to the organizational sustainability literature by integrating collective efficacy and normative processes as key drivers of everyday pro-environmental behavior at work.

Construction industry remains a major driver of global resource use and waste generation, therefore, identifying sustainable material alternatives is increasingly important. Recycled-textile-based insulation presents a promising pathway to support circular economy principles by diverting post-consumer waste from landfills and reducing reliance on virgin petrochemical materials. This study conducts a cradle-to-gate life cycle assessment (LCA) using SimaPro to compare polyurethane (PU) foam and recycled denim (cotton fiber) insulation. The system boundary includes raw material extraction, transportation, and manufacturing. A functional unit of 1 m² of installed insulation with a thermal resistance of RSI = 1 m²·K/W at the factory gate ensures comparability, with mass-based results reported as secondary metrics. The results indicate that recycled denim exhibits higher embodied carbon per unit mass, despite lower production energy and lower cradle-to-gate impacts per installed area, reinforcing the need for a declared-unit-based comparison tied to thermal performance. Air leakage is evaluated separately as a complementary performance indicator influencing in-service energy behavior showing significantly lower air leakage for PU; but is not included in the cradle-to-gate normalization. However, it could be argued that materials with improved airtightness may enable the use of reduced insulation thickness while still achieving equivalent performance, thereby potentially lowering overall material demand. Nevertheless, recycled denim offers environmental advantages by reducing landfill waste and promoting resource conservation through material reuse. A transient coupled heat–moisture model in COMSOL Multiphysics, using climate data from Arizona and Florida, further reveals that denim absorbs more moisture than polyurethane. This leads to larger heat flux fluctuations, highlighting a trade-off between denim’s sustainability advantages and its reduced hygrothermal durability. Overall, these findings demonstrate the limitations of single-metric comparisons and emphasize the need for performance-based, multi-criteria assessments that integrate functional efficiency with circularity. Future research should incorporate occupant health and comfort to enable a more comprehensive evaluation of insulation sustainability. Full article

Previous research provides valuable insight into energy knowledge, attitudes, and behavior in the context of energy literacy. However, a research gap exists in dealing with a comprehensive understanding of complex relationships on energy-related attributes for adolescents. In this aspect, utilizing the framework of the Value–Belief–Norm (VBN) theory, this study highlighted these complex relationships for the selected adolescents as potential future energy consumers and future decision makers. Participants of the study were a total of 530 8th-grade students attending public schools located in a district of Istanbul, Türkiye. To test the hypothesized connections among the latent constructs, Structural Equation Modeling (SEM) was performed. This dataset demonstrates that altruistic values develop pro-environmental beliefs and awareness of consequences directly, but ascribed responsibility indirectly. Interestingly, biospheric and egoistic values showed no significant influence. In line with VBN theory, these students with more strong beliefs about human-nature interdependence develop an awareness of the consequences of their own actions and ascribed responsibility. The finalized model reveals that the relevant behaviors were linked to personal norms that could be positively explained by pro-environmental beliefs, awareness of consequences, and ascribed responsibility. These adolescents believing in the severity of global warming, while focusing on human well-being could be active in creating sustainable energy consumption patterns. This research provides valuable insight into strategies for promoting behavior aimed at reducing the persistent rise in energy consumption. Full article

Microplastics (MPs) are synthetic polymer particles that are generally less than 5 mm in size and have attracted heightened scrutiny due to their pervasive presence in the environment, along with their toxicological significance. Several research investigations documented its presence in humans as a profound finding in biological tissues and fluids crossing barriers, leading to oxidative and inflammatory pathways alterations associated with blood, placenta, cardiovascular, pulmonary, nephrotic, other systems, and their disorders. Given the ubiquitous utilization of microplastics across diverse sectors, it is imperative to systematically investigate and elucidate their potential toxicological effects on biological systems through rigorous and mechanistically informed research. This review will also provide the synthesis of recent mechanistic data on the toxicity that can be caused by MPs and will determine key gaps that impede efficient human health risk evaluation. A structured literature search was conducted via PubMed, Web of Science, and Scopus databases, mostly from the studies published between 2010 and 2026. The studies of exposure characteristics and biological effects were analyzed in vitro, in vivo, and in human biomonitoring, and the primary focus of the interventions includes oxidative stress, inflammation, apoptosis, hepatotoxicity, and metabolic malfunction. MPs possess various physicochemical properties, such as a low particle size, various shapes, surface area, polymer composition, and the presence of sorbed or intrinsic additives. When MPs are taken up by cells, they can induce oxidative stress via increasing ROS, eventually leading to high lipid peroxidation, mitochondrial malfunction, DNA fragmentation, and eventually cell death. MPs also cause pro-inflammatory cytokine responses, including TNF-α, IL-1β, and IL-6, altering the immune system and cell profile, leading to systemic inflammation. In aquatic and terrestrial organisms, these microplastics have a harmful impact on growth, reproduction, and behavior in a time- and dose-dependent manner. Under conditions of controlled exposure, the organ-specific toxicities that have been reported include hepatic, renal, neurological, reproductive, and cardiovascular systems. Although the fields of mechanistic knowledge are growing, there is still a substantial amount of uncertainty; there is a lack of characterization of the long-term effects of low-dose chronic exposure, the kinetics of bioaccumulation, biodegradation potential, and transgenerational effects. In addition, there are no standardized procedures for the characterization of MPs, nor the reporting of the distribution of size or exposure measurements, which limits the comparability of cross-studies and makes it difficult to assess risks quantitatively. The dynamics of interactions of MPs between co-adsorbed contaminants like heavy metals, polycyclic aromatic hydrocarbons, and endocrine-disrupting chemicals are also yet to be explored. Although all evidence available to date does indicate biologically plausible mechanisms of MP-induced toxicity, integrated research employing standardized analytical protocols, an environmentally relevant exposure model, and human epidemiological data is required to ensure that laboratory results are translated into evidence-based public health and regulatory actions. This review offers an in-depth analysis of the existing molecular understanding of MP-induced toxicity, demonstrates organism-level impacts throughout species, and establishes vital fields for future studies. In order to develop competent guidelines to minimize MP exposure and its adverse health effects, it is crucial to cover these gaps via research that incorporates toxicology and environmental science.
