As I said before in another post, if biologists urge more parks to ban dogs to curb dog predation that’s because dogs are the third worst invasive nonhuman animal after cats and rats. A new study would point out they’d even be worse than that, if their impact in Europe and Africa are considered. You might argue that pigs and minks are worse than dogs, but the problem is that not only is it appealing to sentiment but also because their negative environmental impact is less than that of dogs.
It’s not that minks are any better than dogs or vice versa, but the fact that there’s not a big fur industry in other countries (especially in the tropics) minimises their impact which makes it a blessing in disguise. It’s not that there aren’t any animals being used for their fur at all, but because fur traps heat well (maybe too well in some cases) that it’s impractical in other countries. The most commonly used natural textiles in the tropics (and subtropical areas) are cotton and silk, which endear better to those climates than fur clothing ever would. Conversely speaking, the fur industry’s present in more temperate or colder climates.
You might say that dogs are more useful than minks are or are domesticated far longer, but so are mice though you won’t see people admitting this even though they’re extensively used in scientific experiments and are commensal longer than minks are. Then again, dogs are proven to render 11 species extinct and endanger 188 more (possibly larger than that should a new study come out). The real problem has to do if that invasive species (such as dogs) turn out to be charismatic, which complicates matters. It’s pretty much the case with horses.
It wouldn’t matter about how bad they are for native vegetation in places like Australia and America, too many people have a strong connection to horses that it clouds and occults whatever attempts at addressing the problem. It’s the same with dogs, especially in light of the fact that they’re the third worst invasive animal. Being the first domesticated animal, dogs might as well have the dishonour of being the first invasive nonhuman animal. Dog predation has been suspected in some reports and studies, it took a few studies to blow it out.
Feelings don’t matter, once hard facts are brought up. The hard reality’s that dogs are an invasive species, damaging to native wildlife such as sea turtles in the Philippines and Mexico, Barbary macaques in Morocco or Ethiopian wolves in Ethiopia. Since the latter two are in Africa, if African dogs turn out to be more closely related to West Asian dogs and if dogs are proven to negative impact wildlife in Africa then they are invasive and introduced.
But it gets complicated by a strong emotional attachment to these animals (dogs and horses), even if they know they do wrong to the environment they’d turn a blind eye due to this sentiment. This is why it took a long time to recognise that dogs are an invasive species, even if it’s been suspected before. This is also the same for horses and why charisma makes it harder for some invasive species to be recognised as they really are. There’s also a discrepancy between the species’s cultural value and the damage they inflict on the environment.
It’s even called social-ecological mismatches for a reason, this rings true for dogs where they’re valued for many things but they also kill so many wild animals and drive some of them extinct. For another matter, the same can be said of horses where although they cause ecological damage but many people (even those who’re aware of invasive species) ignore this. That is the power of the social-ecological mismatch, if something is charismatic they’ll put it on a pedestal even though animals like dogs are proven to be a nuisance to wildlife.
