Accidental Tourists

Humans have released cane toads throughout the warmer regions of the world, often in an attempt to control insects such as sugar cane beetles. But cane toads adapt to new surroundings quickly and often out-compete native wildlife. They are now pests in Florida, Hawaii, the Caribbean, Australia, and other semitropical locations. Introduced plants and animals are the second greatest threat to wildlife worldwide.
