Is there a world flag?(NJC)

[Relayer211]

       Does anyone know if there is a world flag or "planet earth" flag?My idea is 
instead of waving flags of our countries,why not show that we are citizens of Planet 
Earth by waving a flag of the whole planet?In a deeper,spiritual sense,countries are 
artificial and just one of many divisions.to be too nationalistic is very limited.we 
are all one people...
