Query: Unfortunate

What might be an interesting documentary proves to be just another case of paranoid scaremongering.The director admits "We are not scientists" - and it shows. Such sampling and analysis as are presented are shallow, seem to have taken no precautions against contamination, are apaprently unaware of natural variations in concentrations of elements - which is after all why we mine in some areas but not in others.Scientists are quoted early on saying that geo-engineering would need more investigation before being done - somehow this is turned into a "fact" that it is currently being used for everything depopulation to controlling global warming.Why is chaff even mentioned? Or cloud seeding with silver iodide? What have they to do with anything secret?Shoddy science, illogical reasoning, scaremongering rubbish - this is the sort of nonsense could result in someone deciding to take "action" to stop "it" because they think it is true.
