Part of the problem with America is her reliance upon other countries and other people in general to supply her with food, fuel, and resources. Rugged individualism is what helped to create the economy that we all enjoy today. We will just end up starting over. It will not be easy. If we have to begin over, it can be done.
The average American doesn't have the knowledge to supply themselves with the basic needs of survival. Reliance on technology has made us soft and easy prey. All one really needs to survive is food, water, heat, clothing and shelter. These basics aren't all that difficult to learn and teach. Many of the things that we take for granted will become of great value in a crisis situation and we will need the means at our disposal to protect them. Guns will be scarce as well as the means to make new ammunition. It would be a good idea to learn how to make and use simple projectile weapons.
Bartering will become the primary currency. Those with the knowledge to supply the basics will have great influence in the perpetuation of our existence. I would suggest that any who don't know how to make clean water, farm animals, and maintain a garden should learn how. Forging metals and making simple tools is also very important as well as weaving fabrics. Let's not forget glass and pottery, plus the skills to work with it as well. Granted one man cannot do all those things, but a community that will work together will be able to do so. Not having printed money isn't a problem if you have a skill of value.
We have so much time to worry about silly things that we drive ourselves into anxiety and depression these days. A bird doesn't worry for it's next meal. A lion that will not hunt or a bird that will not forage will cease to exist. Mankind has had it very easy for a good while. The Creator has made this Earth with all the things that all life needs to perpetuate itself. It isn't a problem to survive if one understands that it takes physical hard work to do so and it will not be without peril. Be willing to work hard and have little if any free time to do the frivolous things that we enjoy as modern men. Do not fear, all will work itself out in the end.
The Internet is full of information to help people survive NBC environments. There are military field manuals that have many methods defined in them as well. Use your time to learn these things. It will help alleviate the fear of these unknowns for most folks. We all know that there are no guarantees in life, increase your chances of survival though the accumulation of this information. Hopefully all this survival knowledge will not be needed. Just as it is better to have a firearm and not need it, the same applies to survival skills and knowledge.
Terror is nothing more than a product of fear. Don't let a lack of knowledge create fear, empower yourselves through learning and application of skills needed to survive. I hope that the Moderators understand that this post isn't intended to be a SHTF conversation starter or a thread hijacking. So let us not allow it become one. You my brothers and sisters are the future of this great country. Let's make it the best we can, even if the worst happens.
Peace and good will to you all.
