I am getting fed up with the chemtrail conspiracy theorists.
A friend on FB posted this link:

Chemtrails! Strontium chromate! Air Force whistleblower!

I responded to him saying he should stop all fireworks, ban all resins using stronium chromate as a coloring, and ground ALL aircraft because strontium chromate is used as an anti-corrosive on the metal parts.
sheesh…the government doesn’t have to poison us with chemtrails. Manufacturing is doing that just fine already…
