Because I cook a lot, I use an AeroGarden Harvest Elite to keep my herbs growing in the kitchen all year round. Sure, I can pop the herbs in a temperature-regulated greenhouse outdoors, but when it’s in the kitchen growing at a rapid rate, I can’t resist using them. I chose this specific AeroGarden unit as it is a simple stainless steel design and provides what I need. There are much more expensive versions of the AeroGarden but I don’t need the functions they provide. That, and it’s only for herbs, outdoors I prefer to grow a more yearly stable edible crop of various goods.
This group stresses being able to stay alive for indefinite periods in life-threatening wilderness scenarios, including plane crashes, shipwrecks, and being lost in the woods. Concerns are: thirst, hunger, climate, terrain, health, stress, and fear. The rule of 3 is often emphasized as common practice for wilderness survival. The rule states that a human can survive: 3 minutes without air, 3 hours without shelter, 3 days without water, 3 weeks without food. 
Personal defense items – such as rifles and heavy firearms – are going to be increasinly hard to manage the farther you move from steady supplies. Ironically, it’s firearms that help acquire more food, provide personal protection, and deter others from attacking. In a SHTF scenario, heavy armament is only good within fortified areas. If you want to stay highly mobile, switch down to a .22LR polymer rifle such as the Savage survival rifle or similar. Lightweight, collapsible, and perfect for hunting game. Loaded with subsonic rounds, it can also be a lot more efficient than heading off a target with a loud 30-06.
