Had our Earth been one giant living organism, it would breathe, probably something like once a year to maintain its behemoth size. If you would allow for changes in seasons and corresponding change in vegetation and appearance a view, you might find something like a breathing planet, like these images show. The image was created by John Nelson of IDV Solutions. He downloaded cloud free satellite images of the planet for every month, and let them loose in a gif animation that we see here, and in which it appears our beloved planet does breathe.
