Apart from the survival stuff, everyone must get into a good place psychologically to deal with the coming turmoil. I do believe the death of the dollar is imminent. Start living simply NOW. It's really a good way to live anyway.
No one can predict exactly how this is all going to play out but just be prepared for change. There will be people who will freak out and cause chaos
but there will also be a "coming together" of local neighbourhoods and families and that's good. Instead of just thinking of how you are going to
get through it, try to imagine what skills you can bring to your community that will need all the help it can get.
If you are going to buy seed, get the heritage (non-hybrid) kind so the seeds can be harvested year after year. Most of the seeds you buy today are
engineered so they're no good the next year.
Live in the city? Figure out somewhere to go if things get bad. Any relatives with a farm?
It's not the end of the world but our society is in for some big changes. Like the pheonix rising from the ashes (recent crop circle?) it will all
make us better people.
