And all that the Lorax left here in this mess
was a small pile of rocks, with one word..."UNLESS."
Whatever that meant, well, I couldn't guess.

"But now," says the Once-ler, "Now that you're here,
the word of the Lorax seems perfectly clear.
UNLESS someone like you cares a whole awful lot,
nothing is going to get better.  It's not.

"SO...Catch!" calls the Once-ler. He lets something fall.
"It's a Truffula Seed.  It's the last one of all!
You're in charge of the last of the Truffula Seeds.
And Truffula Trees are what everyone needs.
Plant a new Truffula. Treat it with care.
Give it clean water. And feed it fresh air.
Grow a forest. Protect it from axes that hack.
Then the Lorax and all of his friends may come back."
