The Ecological Square Pedro de Souza Pinheiro, located in Pedro Afonso, Tocantins, has become a point of pride for the local community. This transformation began in 2015 when local teacher Fabrício Rocha, frustrated with the sight of a nearby dump, gathered a small group of students to start a cleanup initiative. As interest grew, so did the number of volunteers, eventually reaching hundreds who worked to revitalize the area. The materials used for constructing the square were primarily sourced from the very garbage heap that once stood there, demonstrating a commitment to sustainability and community engagement. This creative repurposing not only salvaged discarded items but also provided a means for locals to take ownership of their environment, fostering a sense of responsibility for its upkeep. Now, more than a decade later, the once-dilapidated space continues to thrive, surrounded by native plants and bustling with life, serving as a testament to the impact of grassroots initiatives in transforming urban landscapes. The ecological square not only enhances the quality of life for residents but also serves as an example for other communities facing similar challenges with waste management and urban decay.
