ohhh...i like that. Are you planning on filling up your jar with "dear universe" notes? That would be awesome. And wouldn't that be cool to release them into the wind over a cliff when the jar's full? although, I guess that would mean littering, too. :)
ooh, cool idea. was also thinkng of burning them.
Since I don't like the idea of littering either, but want to release them to the universe, I'm buying edible rice paper and writing my thought on it. Then I'll tie it to a tree and the birds will eat them. This, for me, is an image of allowing nature to transform the negative to a positive.
