Humans are vermin.

Sorry about the late response, I was being overwhelmed with homework. I will start by countering your points directly, then the argument as a whole. Yes, human population is extremely large. But that does not equate to difficult to control, as there have not been many attempts to control human population. The only place I can think of is China, where you cannot have more than one child, and that has not been going on long enough to decide whether it is difficult or not. I do not think that we could on any place of the Earth except Antarctica be considered invasive or non-native, considering how long ago it was that we spread to the whole world. We have been around in most places long enough to see the fall and rise of species! Humans are the ones who MAKE the agricultural crops, so of course we are not a threat to agricultural crops, without us they wouldn't exist. That is half of the definition that does not apply to humans. Just because we are a threat to the environment does not make us noxious. Also we are starting to turn around our effects on the environment. That page about the chickens is truly horrifying, but the chicken industry does not represent the whole of humanity. In fact, I think that most people I know would be horrified to hear that chickens are treated that way, I certainly didn't know that. But I think I'm going to have to call you out on a hasty generalization fallacy there. And although the chicken companies are not the only awful thing out there, a lot of it is kept secret to the majority of the population. Also... the source you cited for disgusting was one of those internet lists that exaggerates so that they can have a better title. It meant disgusting in more of an unhealthy way than the way that the disgusting in vermin meant. Context must be applied here. The kind of disgusting that it meant in the definition for vermin is more of a repulsive in looks or deeds word. Clearly the group that will have the largest impact on the collective is not the villains nor the heroes of the world, but the average layman as you have said. You asked "what actions have humans done to make sure they don't act as vermin to the rest of the planet". Most of the time, they don't even need to try hard. Except for during wars, instigated by powerful government leaders, so a small portion of the population, people are not invasive to anywhere as I have pointed out above. Most people don't damage agricultural crops either, unless they are a destructive minority. As for objectionable, anyone could object to anything, and the average person is no more objectionable than average. If so, then the bar for all of humanity is set as high as these heroes that have been mentioned, and why would they be considered heroes for barely meeting the requirement to not be objectionable? Many people in the world are trying to reduce their carbon footprint, and so the main threat to the environment are oil, coal, and natural gas companies. The daily needs of most people in the world are not what is causing environmental damage. Going to the other usage of the term vermin, which people use in everyday conversation about someone being a horrible person. Except for people with mental disorders or people who were raised horribly, everyone has a basic concept of what is right and wrong, and generally tries to abide by that. Humans are not noxious, disgusting, objectionable, or just horrible, and therefore are not vermin.
