Humanity's existence is natural, but humanity's contemporary actions are—by definition—not natural. It is for this reason this very human word "natural" was invented: to distinguish some ("natural") activities from some ("artificial") human activities. It is worth noting that the word natural is itself not "natural", the word is a human invention used to separate our own activities from others.
