Swedish climate activist Greta Thunberg is now keeping a watchful eye over pedestrians in San Francisco's downtown core, where an artist is completing a massive mural honoring the influential teen.
According to CNN, Argentine muralist Andrés Petreselli, who works under the pseudonym Cobre, said he was compelled to paint Thunberg's likeness because he feels connected to everything the young activist has done to try and save the planet.
