Phosphate mining

Please, in regard to phosphate mining and how it is affecting the
environment in the Gulf of Mexico, specifically, the west coast of
Florida and Louisianna: When the uses of phosphate are mentioned
"they" always say they use it for fertilizer and "other" uses.... 
Don't those "other" uses include explosives and neuclear weapons?  Is
that the real reason WHY the powers that be allow the descruction of
our beautiful coast, land, water supply and contaminate the air?  I
read an article in the Carnegie Report that said last month over 20
tons of phosphate was delivered to North Korea!  Would a scientic
expert, please, care to post a comment?  As is the case with petroleum
is phosphate also more about.... follow the money?
Thank you.
