I have never been able to find it again but there was this video from an event called Conspricon 2011 that was wild. Gmo plants mutated to live in heavy metal environments, Gates patent on heavy metal gmo trees. Testing high altitude ponds for heavy metals. Then there was this wild twist where the particles had the same structure as human blood or something?

Regardless, I consider it visual pollution at a minumum. I now feel as though I can call the weather based on my observations.
