Have you flew above where I live? Given the number of planes I see in the sky and the data you did. I live near Paris, and every time you will watch the rivers flowing nearby (may it be Seine or Oise) you will notice this weird patches from the sky near the loops of the rivers. It is/was sand harvesting. It looks like this: https://www.google.fr/maps/place/Cergy/@49.0222789,2.0684055,13z/data=!3m1!1e3!4m2!3m1!1s0x47e6f4c72416d693:0x40b82c3688b34e0 https://www.google.fr/maps/place/Cergy/@49.0222789,2.0684055... You will notice raw montain near montpellier a hole while approaching ORY from london in a place named cormeilles en parisis. You may not notice but it may be insidiously happening near your place, everywhere in the world. Even the desert (cf occidental sahara, UN claim vs Marocco), oceanic islands are targeted. The law of thermodynamics are saying "any pure enough chemical entities are a resource", and the entropy lost will never be recovered without a way bigger energy than the one for harvesting them. Thus the reasoning on fossil energy (Hubert's Peak) also applies for sand, water, potasse, alumine, iron ores, bitumes, absestos, helium, nitrogen, coal, gas, uranium.... Why no one cares? Because there is an economical incentive to ignore the consequence of your actions: the lack of financial liability for the pollution/increase of entropy you are generating. If you make your own compost and grow your vegetables (lucky us) you can build an intuition of what is wrong here. But for the other one, our education makes it impossible to understand the slow cycles of resources. So, I bow.
