50% of my retirement funding is in Australian mining. Is it sustainable? Is it good for the environment? Is it an industry known for ethics?
No, no, and no.
Will they stop mining if no-one holds their public shares? Lol, no, lots of privately held mining companies exist who tend to perform even less ethically.

So, if they're going to dig the stuff up to sell to China anyway, I'm happy earning some money from it. I don't endorse their behaviour, but I do endorse the 10 - 15% return I've been getting on something they're doing already.
