What is the safest way to preserve fresh meat without chemicals?

In the Australian outback on cattle stations they often salt their meat, which preserves it for quite some time. It is great to be able to take this out on stock camps. You should be able to google a recipe for salt meat.

Deep freezing I guess..it will inhibit all microbial activities below zero degrees.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
