Art intervention means making things that help people to think, feel or do something differently. It's like when you draw a picture for your friend to make them happy or when your mom hangs a pretty painting in your room to make you feel calm. Art intervention can be anything from graffiti on the wall, to a sculpture in the park, or a painting hung in a museum. It's a way for people to express themselves and share their ideas about things that matter to them. Art intervention can be a powerful way to communicate important messages, challenge stereotypes, and bring about positive change in the world.
