Street Art is in itself a form of activism. Unsolicited art in the public domain demands public address. It is a strategy used by street artists to stimulate social, cultural, and political discourse in the public arena. They use it to voice protest, provoke thought, to question, expose, resist, to agitate, mobilize, disrupt, reclaim, and largely to democratize public space.
Anti-war, anti-capitalism, anti-consumerism, anti-gentrification, and proenvironment sentiments have become increasingly popular. Street artists question the dominant social, political, and cultural forces at play such as the state, big corporations, the advertising and media industries; they address the balance of power, social injustices, and questionable practices.
