What to Do about Pollution--

This most basic of life's instruction books strips complexity from the world's problems--hunger, pollution, sickness, loneliness--and reveals a single need. Opening with a wide focus (``What to do about pollution . . . Stop it. Clean it up.''), it gradually pulls readers to more immediate, personal concerns (``What to do about the sad and brokenhearted . . . Draw them pictures. Tell them stories. Sing them songs''), and ends with a mother tenderly embraced by her children. The firm, lean text is complemented by the energetic scratches of pen and ink over watercolor. Trivas infuses somber scenes with light and color as the one simple remedy crystallizes: ``What to do? / Love.'' While adults may find this simplification clarifying (and the book's title somewhat misleading), the profundity of the message may be lost on youngsters who haven't dealt with entanglements that frustrate obvious solutions.
