I'm sure you've probably heard of at least a few invasive species. Maybe you've heard of the Cane Toad. It's one of the classic introductions of invasive species gone wrong. It was introduced to eat pests in cane fields and then turned into a plague of epic proportions in Northern Australia. But here is the question. Now that these species are here, is it worth fighting their spread, or should we spend time and effort on other things. It's worth asking, and not just for the ethical implications. We live in a modern world and I think there is a real financial element to this as well. See if you can follow my logic through this video short. Do you agree with my thoughts? Should we keep fighting? Do you have any personal experience with an invasive species?
