On June 5, 2024, King Mongkut’s University of Technology Thonburi (KMUTT), led by the Energy, Environmental, Safety, and Occupational Health Management Center (EESH), in collaboration with the Office of Physical Resource Management of KMUTT Bangkhuntien and various internal organizations, including the Office of Buildings and Facility Management, the Faculty of Liberal Arts, the Master’s Program in Social and Environmental Sciences, the Office of Student Affairs, the Strategic Communication and Marketing Group, the Health and Hygiene Services Group, and the Student Financial Aid Services Group, organized an event titled “Awakening Youth Power: New Saplings, Sustainable Hearts”. This was held in observance of World Environment Day 2024, under the theme “Our Land, Our Future, We are Generation Restoration”. The event took place at the Multidisciplinary Learning Building, KMUTT Bangmod and the KMUTT Mangrove Plantation Area in Pantai Norasingh, Mueang Samut Sakhon District. The activities were aligned with World Environment Day and included exhibitions and activity stations aimed at raising awareness among the new generation about the importance of ecosystems and various environmental issues. Additionally, there was a focus on promoting the reuse of single-use plastics through an activity that involved passing on single-use plastic cups for seedling cultivation of mangrove trees. The outcomes of these efforts are expected to extend to the community, fulfilling part of the university’s mission to engage in Corporate Social Responsibility (CSR) as a Change Agent. This involves disseminating and expanding knowledge and understanding of energy conservation, environmental and safety issues to benefit society and the nation. This initiative supports Sustainable Development Goal 13 by raising awareness about limited resources and preparing for climate change impacts, Goal 14 by conserving water and marine resources, and Goal 15, which focuses on protecting, restoring, and promoting sustainable use of terrestrial and aquatic ecosystems.
