Cane Toads: An Unnatural History (1988) is a 47-minute documentary film about the introduction of Cane Toads to Australia. Cane Toads were introduced to Australia with the aim of controlling a sugar cane pest, the cane beetle, but they over-multiplied and became a serious problem in the Australian ecosystem. It is often humorous, and is used in high schools and colleges as a complement to curricula in biology, ecology, environmental science, anthropology, geography, and communication.
