Well, according to professor Marc Bekoff in this article and this article in the Huffington Post we are.
Yes, we want to eradicate some species from our shores including possums, rabbits, stoats, weasels, hedgehogs, rats and mice, and some of want to go further and include goats, pigs, deer, peacocks cats and dogs in that list.
Does that mean we hate those species? Or does it mean we love kiwi, kōkako, kākāpō, takahē, tīeke, tuatara, wēta and powelliphanta more?
The good professor objects to the organised killing of possums. In fact he’s been recorded as saying “It’s time to put away the guns, the traps, the snares, the poisons. The lives of individual animals matter, and killing is not the answer”. Perhaps the good professor would like to have a quiet word in the possums’ collective ear about the harm they are doing by destroying the forest canopy and that their predation of eggs, birds and insects is contributing to the extinction of many species. He might also like to mention that as they have no predators here, they might like to reduce their birthrate to a manageable level.
Alternatively he might like to find a viable method of non-traumatically capturing 30 million possums and shipping them to Australia. I’m sure the Aussies would welcome all 30 million of them back with open arms. Then perhaps he can suggest solutions for the other invasive species I’ve mentioned.
The professor makes the ridiculous claim that as these invasive species have been here for more than 50 years, they have every right to live here in peace. Our native and endemic flora and fauna have lived here for up to 80 million years. Do they not have a right to live here in peace? Those invasive species we wish to eradicate have contributed to one of the greatest mass extinctions in recent history. As around 80% of our fauna is endemic to New Zealand, if they disappear here, they’re gone for good.
I’m all for treating animals compassionately, but these foreign pests have been anything but compassionate to our native and endemic species. If they can’t learn to get along with the original inhabitants, it’s time they moved elsewhere. We are facing a conservation crisis, so the time to play nice with these critters has passed.
For a viewpoint that contrasts starkly with that of Professor Bekoff, see this article by Elizabeth Kolbert in the New Yorker.
