{"abstract":"The rapid degradation of marine ecosystems is a global environmental crisis. Climate change, overfishing, pollution, and habitat destruction have led to declining fish populations, coral bleaching, and the loss of biodiversity. According to the United Nations, over 3 billion people rely on marine and coastal biodiversity for their livelihoods, yet many of these ecosystems are under threat due to unsustainable human activities. In the Philippines—an archipelagic country rich in marine biodiversity—coastal communities like Kalamansig face significant challenges in protecting their marine resources. This situation reflects a global issue: the disconnect between environmental awareness and meaningful action. I was motivated to conduct this study to understand how young people, particularly students, perceive their role in marine conservation within their local setting. Using photo-elicitation as a participatory tool, this research aimed to empower Grade 10 students from Kalamansig National High School to document marine resources and reflect on their significance. By capturing and discussing their own images, students developed insights into both the ecological and economic value of marine life. This approach aligns with the global call for environmental education and community-based action, especially among youth, to address the growing threats facing our oceans and coastal ecosystems.","abstract_source":"original","authors":["Friezenith Calamay","Christine Abo"],"date":"2025-05-24","doi":"10.70838/pemj.380509","id":5308,"issue":5,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"ea58fbf6b598623692c6af08e2590165aafd05ef5964230d9a5769afd9742db3","schema":"scimatic-article/1","title":"Exploring Marine Resources: A Photo-Elicitation Approach by Science 10 Students","volume":38}
