The cane toad has been a huge problem in Australia for the past 80 years; however, a new invasive toad species, which may be just as damaging, is currently destructing the food chain (from the top down) in Madagascar. The bumpy, toxic toad from Southeast Asia, Duttaphrynus melanostictus, has spread rapidly throughout the island in the past year. Scientists suspect that the campaign to eradicate the toad would cost $2 million to $10 million if they take action now. However, the toad currently inhabits a major canal, which could be like “building them a highway to the rest of the country”, and possibly the world through shipping.
Sometimes, we just don’t learn from history. The can toad infestation was a national crisis for Australia, and scientists are trying to point out that Madagascar’s situation will dramatically worsen to a similar disaster if action isn’t taken soon. However, the mining company whose shipping containers provided the pathway for the invasion aren’t claiming responsibility, so funding is lacking. It is discouraging to watch such situations from afar; 70% of Madagascar’s species live nowhere else on Earth, so it is especially crucial that these species, who can provide a lot of insight into evolution and biodiversity research, are protected.

I completely agree with everything you said in your second paragraph. Have we learned nothing? These problems tend to amplify on islands too… especially poor ones. And what do you think, is the mining company a Madagascar company? Doubtful. This is where there is a need for command and control, imo. Somehow justice needs to happen- $2-10 million may seem like a drop in the bucket 20 years from now.
It certainly does seem that this animal could wreak havoc on the natural systems and it will take a lot to stop it. Do you personally think this project is worth the millions?
