How could the Once-ler have managed his company to protect natural resources and not run out of trees to manufacture “Thneeds”? Is it necessary to protect all trees “from axes that hack”?

What did the Once-ler mean by “UNLESS”? What responsibility does he seem to think “someone like you” needs to take? What kinds of things can we do today to ensure that trees will be available for all different purposes in the future?

Compare the Once-ler’s attitude toward the environment at the beginning of the story with his attitude at the end.

The Once-ler explains his actions by saying, “If I didn’t do it, someone else would.” Is this a good excuse for doing what he did?

The Lorax says he speaks for the trees. What does this mean to you? What is the Lorax’s attitude at the end of the story?

What seems to be Dr. Seuss’ purpose in writing this fable? (A fable is a fictional story that teaches a lesson.)
