@Helli The second problem, apart from the environment, is that extraction and, above all, further processing are very complex and expensive and therefore it is not feasible to extract it here at the current prices. This is why there will be fixed purchase agreements with higher prices, as is already the case at $MP.
@Helli The cosmetics industry in turn relies on desert sand, as it is particularly fine for powders etc. There are also documentaries about it, very interesting.
@Helli Sand (but as you rightly mentioned, not desert sand) is mainly needed for concrete and is stolen from riverbeds in many countries. This causes a lot of damage and seems to be a very lucrative business for criminal organizations such as the mafia.
@Helli is actually correct. France is even fighting a massive battle against organized sand thieves who dig up beaches in night and fog operations, because the sand there is ideal for building.
