As the world moves to cities, so does art. And just as art can inspire political action and resistance, so too do the walls of the city become canvases for important street art messages. The graffiti and street art on this list is perfect for spreading messages about environmentalism and climate change to a wider audience.
This street art uses simple slogans and provocative images to spread important and inspiring ideas in ways that are easy to remember. Such art can inspire people to action or at least remind them about important issues that they may have forgotten.
