Thank you both for your comments.
It is true that human presence is mostly absent from my photos. Most times, you can only deduce such presence through the by-products of its activity...
... Like on this photo, taken on the barren high plateau at the foot of Mount Lozère, the most deserted area of France... Small streams crisscross the plateau, and in the early Middle Ages, Man saw fit to build this small stone bridge, which was much later given a parapet. The general landscape is pretty much unchanged since those days. The red and white paint dashes are, of course, modern and signal a hiking trail.
