That book is what really opened my eyes! I'm getting ready to read all three again just to refresh my memory.There's a great novel called One Second After by William Forstchen. It really lays it out as to what will happen to most of us in the event of an EMP which would knock out all electricity. As someone said earlier--survival is for the young. People my age probably won't last long. That's okay--we've had our lives.
My chickens can manage during the summer, but not sure what I could get them in the winter. I have a couple of bags of wheat that have been sealed and that wouldn't last long. I have dogs and cats and have told everyone that if it ever comes to it they are all on the menu.
I have a small pond that would serve and several "life straws" that I think are an amazing invention. They allow one to drink water anywhere as they filter the water through the straw. There are many internet resources available on how to get fresh water etc. anywhere.
I have a wood stove I can cook on, a large cast iron pot and frying pan. Living in the woods fuel is not an issue.
Though I have about 100 pounds of rice in the freezer to protect it from bugs, I imagine we will eat the bugs if need be.
There are black walnuts, fruit trees and acorns locally. I have processed acorns out of curiosity and they were not good. Still, if that's all there is... Of course poke weed in the summer and berries. I have books (not electronic) that are reference books on what is edible.
I know how to save seeds but perhaps more importantly, I am part of a large community garden. There are farmers in the area and barter is a good option.
Regarding global warming, it is a reality. I'm not certain about this but I believe we were headed into a cooling period which has now been offset by human activity. Yes earth has had periods of ice and heat but these changes usually took place over hundreds of thousands of years -- not decades.
