Do you have any understanding of how impossible it is to raise the aluminum content five times? You’d need an endless row of dump trucks, not some contamination in a spray.
And here’s the thing: he’s not talking about some pure metallic aluminum, either. If it was in powder or granular form, it would have oxidized virtually as it was sprayed. If it were deep, the lack of oxygen could slow oxidation, but how would a plane spray something deep into the soil?
Do you realize how long spraying has been occuring? Day after day, year after year. Decade after decade. Hell, nice clear blue sky days are noticeable here in northern CA because they are actually rare. They stopped spraying when the World Cup started and it was a glorious 2 weeks of blue sky’s and evenings that didn’t haze up with the BS expanding lines in the sky. They just cranked up the spraying again last week. Maybe people just don’t pay attention. Got their heads in their phones and never just spend time looking up in the sky.
