{"abstract":"The indiscriminate disposal of solid waste poses a significant threat to environmental integrity and human well-being, necessitating robust waste management approaches. This study comprehensively assesses students' involvement in solid waste management practices at Union National High School in the Philippines, aiming to evaluate awareness, attitudes, and practices regarding waste management. The main objective is to identify strengths and areas for improvement in students' awareness, attitudes, and practices regarding solid waste management, providing insights to support targeted interventions and programs promoting responsible waste management practices. A descriptive survey spanning grades 7 to 12 assessed levels of awareness, attitudes, and practices, revealing varying levels of awareness among students, positive attitudes towards waste management, and practices ranging from adherence to desirable behaviors to concerns such as improper waste disposal. Analysis of the mean percentage indicated consistent awareness, attitudes, and practices among students with affirmative responses, suggesting a need for targeted educational interventions to enhance understanding, foster positive attitudes, and reinforce responsible practices. Overall, the findings underscore the importance of holistic waste management education to bridge knowledge gaps, shape attitudes, and develop practical skills among students, empowering them to contribute actively to sustainable waste management efforts and promote a cleaner, healthier environment.","abstract_source":"original","authors":["Jhondel Baranggan","Sheilla Yamba"],"date":"2024-03-12","doi":"10.5281/zenodo.10806782","id":2650,"issue":1,"journal":{"issn":"3062-312X","name":"Journal of Advanced Studies in Life Sciences"},"pdf_sha256":"0a54fcb1c8ca0265487c036d845a0a77e2783930a913e7e62b2d6d97581f69b3","schema":"scimatic-article/1","title":"Empowering Environmental Guardians: A Holistic Assessment Of Solid Waste Management Practices Among Students At Union National High School, Philippines","volume":1}
