You admit space is uninhabited. Your unnecessary and petulant copy/paste of the definition of pollution includes the words "poisonous" and "harmful". Which isn't possible to do to an uninhabited area. I have no idea why you keep forcing such a contrived idea, other than to draw in a political "bad humans, always polluting" message. Anyway I'm done with this silly conversation. Have fun

Much of our terrestrial pollution took place in "uninhabited areas" which decades later became inhabited. Your comment is reminiscent of 19th and early 20th century attitudes toward pollution.

It's true that it isn't a problem -- until it is.

I'll acknowledge that harm and poison require a reference for where the harm is done, but I don't think it requires human interaction necessarily.

We are able talk about harm being done to insect populations or coastlines or any other inanimate objects. Again, humans, and their politics, aren't necessary.

I don't find my quoting of the definition as being petulant. I was wanting to frame the conversation around a shared definition of the word rather than asserting requirements.
