but I didn’t want to start a new one on a previously covered subject. (this thread tells a little about coltran). Apparently, people are being killed over this also. Plus it is bad for other animals and the environment where it is being mined.
Our local paper had an editorial about this by a biology teacher from the local university, St. Cloud State. I know this man personally, and he and his wife, also a biology teacher, have been to Africa, and do not write unsubstantiated editorials. It really made me think.
