If a Solar Storm of that magnitude were to hit the earth today, it could cripple our culture and in effect send us back to a simpler time...such as in 1859. Satellites would be wiped out, whole power grids could go down, entire continents could have their lights go out. Governments might collapse if they can't communicate and coordinate. It won't be a pretty sight!
There are things that our governments can do to protect against this coming storm; whether they do them or not we will have to wait and see. I'm not that hopeful...most times governments only act after the disaster hits. There is something that you can do though that will prepare you for this scenario.
You can just turn it all off. Take a weekend and camp out in your house or out in the woods if you want. Don't use your cell phone, watch TV, listen to the radio, or do anything that requires modern technology. This will be a great time to use all of your survival gear that is in your bug out bag. Learn how to deal with life without its modern conveniences. You will learn some things.
You will learn that life can go on without electricity. You will also find that you are refreshed from the experience. You had more time to enjoy yourself, your family, and this wonderful world that we live in. You were able to clear your mind...and reboot your brain. You will discover that you are more productive and you have a better appreciation of your life, and the miracles of technology.
