Sure, we do have waterboxes, that is to say, a comprehensive water quality sensing instrument that is part of our civil IoT platform. So, we’re quite confident, if not super confident, of the actual cause of river pollutions because we know where to look at and because rivers are fixed most of the time. But like random burning, in random places, of course, it’s not planned so we cannot actually tell our drones or other vehicles of higher resolution to look.
