Because of course we can mine the whole Earth crust. It’s a good thing our ability to effectively mine in not limited to a few kilometres and our ability to actually find ores is so amazing. I’m such a fool, sorry. More seriously, I’m done with sarcasms. We actually need to recycle aluminium. Smelting is far more energy intensive than extraction and depletion is a very real problem. First, viable gisements are not that common. Second, as we extract the best, we are faced by poorer and poorer quality of ores which mean the cost of smelting gets worse and worse. Aluminium is definitely not endless as someone would have you believe in a reply.
