Outdoor sculptures have evolved beyond mere aesthetic objects, now embracing ecological themes like seed balls to foster sustainability. Artists integrate seed balls—compact mixtures of clay, soil, and seeds—into sculptures, transforming public art into tools for environmental education. These installations often feature biodegradable materials, allowing the seed balls to disperse naturally over time, encouraging plant growth in urban areas.

This fusion of art and ecology not only beautifies spaces but also engages communities in conservation. For example, some sculptures are designed to crumble gradually, releasing seed balls that bloom into native flora. Others invite viewer interaction, letting people take seed balls home to plant. Such initiatives highlight how public art can address climate challenges while inspiring grassroots action.

By merging creativity with functionality, these sculptures redefine the role of art in urban ecosystems, proving that even static installations can actively contribute to greener cities.
