The article portrays the journey of a girl who, during her elementary school years, participated in a youth group called the 'Space Boy Scouts'. She admired the organization's focus on exploring science and dreaming of humanity's peace and future. Now, two decades later, as a seasoned elementary school teacher, she dreams of a sustainable world and actively implements her vision through environmental education initiatives.

In her role as a science teacher, she embarks on practical applications of sustainability, effectively engaging her students in environmental education through projects like the '5-Minute Environmental Education' and the 'Green Keeper' club. Through initiatives such as tree planting for Earth Day and beach cleanup activities, her students express growing awareness and enthusiasm for environmental responsibility. These engagements culminated in their participation in the '3rd Earth Festival', where they not only learned about carbon neutrality but also felt a sense of accomplishment through competitions and direct actions aimed at protecting the planet.

Furthermore, the impact of this initiative extends beyond educational settings, as students collectively donated more than half of their school prize earnings to organizations focused on environmental, human rights, and animal rights causes. This article encapsulates the transformative influence of youth engagement in sustainability and highlights how early exposure to such practical experiences can lead to a more conscious and responsible generation, eager to protect and preserve the earth.
