But what about kudzo?
> Kudzu, a perennial vine native to Japan and China, was first introduced into the USA in 1876 and was actively promoted by the government as a “wonderplant", It expanded to cover over 1 million ha by 1946 and well over 2 million ha today. When Kudzu invades a forest, it prevents the growth of young hardwoods and kills off other plants. Kudzu causes damage to powerlines, and even overwhelms homes, Kudzu has invaded important protected areas, requiring significant investment of management resources, The management response to date outside the protected areas has been insufficient to deal with this very significant threat.
Sounds like an asshole to me.
Is the OP killing them because s/he has no other alternative to feed himself/herself, or is it because of the annoyance even though s/he is in their habitat?
But defining "the health" of an ecosystem is tricky. An invading invasive species is better adapted after all, and it is part of nature.
We need clearer understanding of what we mean by nature and what we are protecting. Are we just trying to hold on to some moment of time in a dynamic ecosystem? Maybe. Protecting the status quo might be practical in terms of human survival, but this doesn't feel like a moral invariant that some people hold it up to be.
All this said, I feel a deep connection with nature, and I recognize this most likely comes from us evolving alongside it. But I recognize my own bias; I care less about mosquitos and more about birds.
If this was your house, maybe, okay. However, when you go camping, you are technically a guest in the bug's house.
