I know why, people are too lazy to pick up their trash when they are done with it. I've had a couple of times, where I have come across a bicycle tube someone flatted, rather then take it home and dispose of it, they left it on the path. Usually they aren't the $2.50 tubes I use, but the super light $25 tubes, if I see one, I collect it, usually a 5¢ patch is all it needs to return it to service. If it's split or the the valve is shot, it goes into the nearest dust bin. Which is what the idiot that tossed it, could have done, just as easily.
