I've been reading about this, and please don't laugh - but I really think heavy metal contamination is going on here at least in part. Google geoengineering one word just like that, our entire environment is being contaminated by aluminum and its sprayed in such minute particulate that its being absorbed into marine life and fish in the wild are showing symptoms of this. I think it self replicates. I know thats science fiction creepy but that's what I think. Our natural environment is not so natural, any more.
Test him for aluminum, that's what I say.
