Filipino director Francis Xavier Pasion posed the question after observing fellow fun-runners in the Nat Geo Earth Day Run last April 22, 2012 throw their paper cups and bottled waters on the street. In his Facebook post, Pasion said he hopes "the organizers did not place plastic bottled waters or papers cups in the various stops of the race. I hope they reiterated upon registration that the runner must bring his/her own container and that water [fountains] will be stationed instead. That could have saved them more money, and, yes, some trees." He added that organizers should be clear with their intentions in organizing such events.
