I don't remember many of the details, but I have this recollection of a short story set on another planet with an indigenous floating balloon-like plant species, which is being harvested or farmed by humans. There's a conflict between two characters that results in a large number of the plants being destroyed, possibly by being shot with a shotgun, or set on fire (they may be filled with a flammable gas?).
I think it's at least 15 years old, possibly older. It may have been part of an anthology (not specifically sci-fi) of short stories by "young authors."
