A Vancouver Park Board commissioner is calling for a ban on balloons which he says can be dangerous to both wildlife and children.
Green Party Park Board Commissioner Stuart Mackinnon says the latex or plastic globes may be whimsical, but even the green ones aren't really green.
His motion calls for a ban on balloon use in city parks and recreation centres, the very places where balloon are often part of the draw at events.
