If a catastrophic world-wide event happened that wiped out a large portion of our population, infrastructure and destroyed many of our natural resources, what skills do you have that would be useful in rebuilding? What skills would you like to learn? You might have stockpiled food, water, ammunition and guns, but thinking beyond a few days of disaster can put you ahead of the game. Knowing a little bit about all those essential skills means you can not only provide for your family, but also be a good bartering tool. Any trade skill makes an excellent hobby—do you like to tinker with cars? Then you have some basic mechanic skills. Do you like to grow your own vegetables? Why don’t you expand that knowledge and raise some chickens?
