Right, but we typically use the term "natural" in contrast to "artificial", where the latter implies that the selection pressures are intentionally applied by humans in pursuit of specific outcomes, and the former implies that the selection pressures are not being created or curated by humans.

We make semantic distinctions like this in many areas: e.g. if a house burns down by accident, it's just a fire, but if someone deliberately set the house on fire, we call it arson.
