I suppose we will have to be happy that they even sell those. Otherwise, we would have to make a run for the ship when night falls and stay stuck there, and for that we may as well be sailing to another place.

[Not to mention that he's not even sure if being on the ship would be safe, if wind picks up and carries the pollen to where it is...]

Mmm, how exactly is Korra's water bending right now? Drying them from all water could be an option, assuming that's doable with water bending. Or we could try to bury them all, they can't release pollen into the air if they are stuck underground, can they?
