Dr. Seuss S01E05 - The Lorax

A young boy goes to meet a ruined industrialist, the Once-ler, in a treeless wasteland and hear his tale of what happened to him. His tragic story is about how he began a thriving business selling Thneeds, a product of questionable merit, derived from the tops of Truffula Trees, plentiful in the area. As his business booms, the forest and its inhabitants suffer as he wantonly clear-cuts the trees, without regard to the warnings of a wise old creature, called the Lorax, about the dire consequences of his greed.
