what in the world are they spraying?

very informative seven part video on chemtrails

Large amounts of aluminium particles are being sprayed over our heads.  This is very harmful to humans, causing diseases such as Alzemier's; it also makes the soil too alkaline, damaging vegetation worldwide. Barium and other chemicals are also being sprayed on us.  There are many aspects to this - from geoengineering and weather control to an attack on human health and fertility to transmitting electromangnetic impulses from Haarp.  There is one thing for sure - it's not a good thing, and needs to stop.
