Scholars debate the specific definition of “street art” yet generally agree that it encompasses ephemeral works in public spaces that are typically unsanctioned by property owners or legal authorities. Encounters with street art are free, accessible, unmediated by formal interpretation, and often unexpected. The communication between the subversive artist or graffiti writer and the unsuspecting passerby is direct and immediate. It is no surprise, therefore, that much street art is activist art that seeks to raise public awareness, confront systemic problems, provoke political dialogue, and promote social change.

Among the many issues that have been addressed by street artists is the unprecedented negative impact humans are having on the ecological systems that provide life support to us and all other species with whom we share the planet. This educational database documents examples of global street art that address multiple facets of the ecological crisis, including climate change, biodiversity loss, pollution, waste, environmental injustice, and more. It also includes hopeful artistic visions of regeneration and sustainability.
