Rick:  The same reason the same human detritus carries full cans/bottles of beer, soda, alcohol and food into the land and too lazy/stupid to carry the empties out or put in provided containers.  The same reason the same garbage flies out of vehicle windows.  The same reason walkers drop the same garbage on the street after consumption.  The human animal performing its superior domination over all of creation.
