Seller of Fresh Air

Once upon a time in a future trees will value more than diamonds, or some other useless thing we give so much attention. Because, once upon a time humans build, build, build and then realized that forgot to plant trees...and started to breathe heavily ...

So they remembered the trees, but now trees wouldn't grow so easily ...and became new value.
