Chemtrails are prevalent here in Ireland too Paulette. I've been aware of them for a few years and once thought it was a mass population-reduction poisoning plan underway...which of course is happening, it's common knowledge that heavy metals screw us up in so many ways!
Yet i also feel that with this being cycle 24 of the sun cycles, with a particularly strong solar max expected, i also considered that the chemtrails of metal particles were perhaps an experiment to deflect the solar radiation back up into the atmosphere to reduce the intense radiation impact on earth - which we're already experiencing anyway.
Who knows the true purpose behind them but whatever the reason, as you said, it's a form of pure evil.
