Well, Australia has two massive issues: mosquitoes and cane toads (poisonous). Both species are invasive. They developed an agent that should, within a year or so, kill off 80% of the population of mosquitoes, which the cane toad eats. Since they want to get rid of both species, this will affect species far outside those two, as other species eat both of the aforementioned species. Australia has imported cane toads, foxes, rabbits, domestic cats (now at epic feral proportions), camels, and more, which has upended their indigenous species, which are now dying, some bordering on extinction. I think when humans tinker with nature, we don't look too many chess moves ahead. We see gain in one area, not realizing we will affect ten other areas.
