The #1 threat to earth (rather I would say to us)

I am convinced that previous civilizations much more advanced than we are today existed on earth.

Was it a weakening magnetic field that caused so many ancient civilizations to go underground?

If chemtrails are real, is it being done to strengthen our magnet field or perhaps protect us from solar radiation?

Really the only thing electrical was basically the telegraph system and it fried things for miles often injuring the operator.

The same thing happened on a smaller scale during the 80's when a Solar Flare was so intense it knocked out several satellites on the west coast. They at that time used sat's for credit card verification of washes and gas purchases. We haven't had anything that intense since, that I know of. But whats being ignored with the 1859 evidence is that wire stretched for miles makes a good antenna for the EMF produced during a heavy Solar Flare. This is what is so frightening about EMP weapons they produce the same kind of damage.

So ask yourself what spans for thousands of miles above ground and traverses the United States several time in all directions? You guessed it power lines... The government knows this has spent millions of studies but nothing has been done to rectify it. Power lines will act the same as telegraph lines in 1859. The low frequency of a EMP Weapon or Solar Flare will destroy the power grid. 

This is what I tell the wife after we went to visit friends from the military on leave in West Virginia. His family lives on a mountain and the mountain is like the family tree, with the oldest living at the top. They owned the whole mountain like the Waltons. Driving up it was, oh that's so and so's top to bottom. I found it very heart warming. Needless to say a the top is where we went, the deer meat cooler was a huge walkin a good 10 X 20' long, with a cellar full of canned foods from their garden surrounding the house. I doubt they would even recognize when the SHTF happens, it will just be Ma the powers out again. No internet there, little TV, just their life moving slower than slow for the nicest people I have ever met. Right out of the movies.
