Invasive Species Control

Comments debate the risks and ethics of using biological controls like introduced predators or modified organisms against invasive species, citing historical failures such as cane toads in Australia and possums in New Zealand, while highlighting potential ecological imbalances.

This case it's probably being done to recent invasive species... As in the ecosystem was fine before they came, and will be fine after they're gone again.

You do realize this is an invasive species that doesn't even belong in the ecosystem in question? Would you also oppose controlling fox and deer populations in Australia?

With so many invasive species, what could go wrong ?/s

It sounds like the implication here is that it's acceptable to use an invasive species to deal with pest problems. There are alternatives to dealing with pests that don't involve decimating bird populations.

To be honest, I don't think I buy this. I'm from NZ and we have a number of introduced species (possums, stoats) which have a dramatic impact on the native wildlife.A lot of bird species in NZ are unique and only found here. They're almost all critically endangered or at risk [1], as they evolved with no natural predators.I'd rather we try and control these introduced species so we can keep (at least some of) our native birds.[1]: <a href="https://www.doc.g

It's an invasive species which IMO changes things.

This frightens me a bit. In Australia, the introduction of camels, toads and various other plants and animals has devastated the countries ecology. New Zealand struggles to keep foreign invasive species out of their country.I know this is suppose to target only one species that spreads a variety of diseases, but misquotes do serve a purpose. For one thing, they fight overpopulation by spreading disease. :-P But they are also a food source to many animals.Even with all the careful planning

Chances are, he will do more harm than good.This field does not have great track record. See, for example, the introduction of the Cane Toad to Australia: https://en.wikipedia.org/wiki/Cane_toad#Australia

Great, let’s create the ultimate invasive species

We're going to rue the day we started doing this.As they say 'Nature abhors a vacuum' - Once the diamondback moth numbers have declined significantly, another (probably more invasive) species will rise to take it's place.The planet's ecosystem has had billions of years to balance itself out, who are we to assume we can do it better?
