Lorax by Dr Seuss

The Lorax is a children's book, written by Dr. Seuss and first published in 1971. It chronicles the plight of the environment and the Lorax (a mossy, bossy man-like creature resembling an Emperor Tamarin), who speaks for the trees against the greedy Once-ler. As in most of Dr. Seuss works, most of the creatures mentioned are original to the book.
