List of survival gear that I think would be useful in a post apocalyptic world.
1. Knowledge – This starts with having an understanding of how the human species acts during a long term survival situation. Find some history books on amazon about the black death of 1348 – 1350. Read those books and get a grasp on how people acted and what they resorted to. Some of the stories look like they came straight out of a Hollywood movie – like starving people digging up dead bodies to cannibalize the remains.
Part of your survival library should include resource material on gardening, raising livestock and farming.
First aid manuals with information on diseases and wound treatment.
2. Water filter – Without safe drinking water, society and life as we know it can not exist. Diseases like Cholera, Typhoid, E. Coli, Cryptosporidiosis, Giardiasis, Shigella and Salmonella can wipe out entire communities in a matter of days.
