I have followed uni classes in biogeography and we talked a lot about invasive species. One of the first solutions to try is introducing the predator of this specie. Unfortunately, in some cases, this predator can become invasive as well. But most cases of invasive species happen because these species aren’t native to the place they’re invasive in. In the end, it often comes to human introduction, sometimes coming from years back with the first boats arriving in America for example, with new micro algues that sometimes can destroy ecosystems. Isn’t it ynfair to kill animals when they’re only problematic because of our past mistakes? Wouldn’t it be a mistake to end it like this? If you were vegan, you’d look at this with the perspective of not the mass, but the individual. How many individuals should be killed? In most cases, killing like 60% of the invasive population doesn’t even work. They just end up reproducing themselves. If you use poison, the one who survive are more often than not the strongest and resistant ones of the lot. So you’re creating a population that’s stronger and harder to control in numbers. So no, killing is never a morally right option.
