Humanity has an outsized impact on the world (natural and artificial). Our influence has impacted nearly all the ecological niches on earth. That said, assigning moral agency to me (or you) for that depends on a series of logical connections between ways of being and the human impact on the world.
We each choose (somewhat - hard to choose to be born in the first world) how we live, but individuals have limited agency for what "humanity" does as a whole. It's all well and good to say "humans bad" (and I don't totally disagree?), but that perspective has been out there for a while and humans are still doing the bad things. Seems like we should search for different approaches.
Oh, you're a "social ecologist" aren't you?
There is nothing fascist or right-leaning in the notion that human activity largely has a negative impact on the natural world.
