He may get too emotional sometimes, at least for my taste [1]. Maybe this 
means something good about his intentions? As of some of you guys making 
fun of his worries, there are moments when your optimism level resembles 
me of certain figures from Monty Python shows (if there is no such show, 
it sure should be). Just MHO.

As of news, I read quite some of them. I have even read some news long 
before I subscribed here (yes, there were news then, too). Sometimes I 
disagree with Eugen and but sometimes I think what he says is worth closer 
look. That's all.

Maybe. I don't think it will make sense to pulverize every cubic meter of 
rock just to have a gram or few of Th. Doesn't look economical. So I still 
do not buy your assertion with so many zeros on the wrong end. Since U is 
only slightly (3-4 times) less omnipresent in the crust, you should say 
now "we will run out of U in 400 million years, so we don't need Th at 
all". Why then you get so emotional about Th? We have 1/4 of the crust to 
mine for U. Leave the hapless greens and start building nuke plants :-).

[1] I don't think humanity cares much about its future and any problem so 
far has been successfully solved, stealing first, then killing and as a 
last resort, cannibalism. So not much to fret about really - seems like 
anything aimed higher than those solutions is not going to get significant 
traction. This of course has some good sides, like our silence will be 
inspirational for some better brained species, because for us it obviously 
is not, we just keep asking, never dare to formulate answer, heh.
