Artists and architects in cities not only design physical entities but also through their artwork shape the mindset of urban population. Whether abstract or spatial, the urban murals have a unique ability to evoke a reaction within the people, unlocking new perceptions, and new mindsets. The art activism has now transformed from rebellious to reformer views. With the first world-wide climate strike, the artist has turned to streets making them a canvas of climate change issues. From streets of San Francisco to wall of Bristol, the art has now become a way to express a “new movement” in the fight against climate change.
