You could say the same about plastic, it’s just oil that is refined and hydrogenated. We didn’t make any of the parts we just pump it up, take them apart and put them together in a different way.
The same with concrete, it is not naturally occurring, it’s something we make separating parts and putting them together again in a different way. The key part being cement which is a very heavy process to make, both chemically and energy wise.
Concrete and Cement are absolutely not natural occurring materials, and they are generally hostile to life due to their chemical caustic composition.
You can’t honestly claim that for instance a barren concrete parking lot is natural.
We do maintain those barren concrete parking lots to stay as clean as possible and, because of this, they stay hostile for life ! … but the minute we stop keeping them clean, vegetation takes over like on most barren rocks in nature. We do so because we, humans, like it like that.
Unfortunately we have also created disaster chemical zones after heavy industries have left some lands. And if we try to live there we get very sick.
i will not try to come up with a clear definition but for me something natural or artificial is not a yes or a no question, but rather a more or less question.
