Do THESE things to be prepared for food & fertilizer shortages, self-sufficiency, war, grid down

Make sure you have physical books and printouts of critical information. Do you know how to get around with a map and a compass? Do you know how to purify your water to make it safe for drinking with bleach? Do you know canning times for foods you are growing in your garden? What about the things in your freezer in case the grid goes down and you want to preserve them in jars?

Here are some links that I hope will be helpful:
