Answer:
Cane toads in Australia have had both a negative impact and positive impact. They were brought to Australia to decrease the population of pests that damage sugar cane, and that's what they did. But because the cane toad had no natural predators, nothing was preying on them to lower their numbers. And because they reproduce very quickly, they're population grew rapidly and they started migrating to other areas of Australia. The cane toad also kills native wildlife because they are poisonous, so our native wildlife was killed as a result.
