When the astronauts are looking at the Earth from the space, they see a blue sphere, covered with a layer of clouds, and between them the shapes of the continents. But what they do not see are the borders of states as we know them from political maps. Today, when we face a climate crisis, a symbol of planetary unity (a flag) might be meaningfult to shift our thinking. In 1969, John McConnell designed the Earth Flag to celebrate the Earth Day. Since then, many others have tried to design a universal flag for the blue planet. However, neither of those was universally accepted. The Flag of the Blue Planet (created for Pohoda Festival, now at Nová Cvernovka in Bratislava) is based on McConnell's proposal. But at a place where the Earth image should be, there is a round hole. The sky, visible through the hole visually reminds of the Earth seen from space.
