I became interested in this topic because of the current happenings in my area. We started seeing an increase in the population of foreigners (mainly Asians) around our community. Most of them are engaging in illegal mining of materials that we don't know. Some of them were arrested and we later discovered that they were mining some rare earth metals.
It's kind of sad that I get most of my world news from posts on this forum, but nevertheless I'm thankful that there are people here from all over the globe and that members like you write about thing like the above, which would probably never be reported on the TV news where I live (so thanks).
And being somewhat of a chemistry geek, I found that pictogram (or whatever the hell you call it) informative; some of those elements I was aware of in terms of their industrial importance--like copper and the platinum group metals, but bismuth and gallium and a few others I had no clue about. So people are just barging into your area to dig up these metals? That has got to cause some serious tension, not to mention legal issues. I'm trying to picture that happening in the US, and my guess is that any foreign miners might last a day before law enforcement booted them out on their asses. Man oh man.

Ugh....I would have merited your post, but after looking way back in your post history it seems clear you've either studied English very studiously or you're getting some help from this forum's dreaded nemesis, AI.
