Plants.
Now stay with me here. It is a post apocalyptic world where zombies are thriving on not only humans but also animals. After a few months you start to realize that there are only so many squirrels a person can eat, and there is a fat chance that the deer population is going to continue to hold up.
You find yourself looking to more renewable sources of food, the kinds that zombies aren't scarfing down greedily: plants, fruits, vegetables, fungi, and herbs.
Although your small tomato garden at your makeshift camp may last you a little while, you are going to need to learn about your local EDIBLE, wild, vegetation for scavenging.
No one wants to be that ginger from the Hunger Games that gets screwed over by a few bum berries, or like Alexander Supertramp who never thought that his saving sustenance would eventually cause his demise. (Respect to him, may he rest in peace)
Do yourself a favor and pick up a field guide to edible plants, and make sure to study hard and read the fine print. It may be the difference between having dinner, or becoming fertilizer for the thing that took you down.
I really like the way you set this post up, it kinda made it seem like an advertisement - very witty, and great pop culture references.
On another note, I agree with you 100%. It's the little things like this that make a huge difference in a post-apocalyptic world. So many people are accustomed to going to the supermarket, buying prepared foods, that many wouldn't even know how to stay alive in the wild. I am currently in a home vegetable garden class, but that only gets me so far. Definitely going to take your advice and learn about wild plants.
I think you make a very good point on an aspect that is seldom discussed in class. While I think it is definitely essential for a survivor of any type of apocalypse, there are also some location requirements that need to be meet in order to be successful in anything beyond scavenging. In order to set up a steady flow of food one would need a protected location (from zombies or thieves) with an appropriate climate and good soil conditions in order to have any chance at all. They would also need it to be somewhere that already has some plant life in order to acquire the seeds required.
This is a good post and an idea I haven't thought of yet. Not only will it give you a more balanced diet, but it will also be much easier to gather if you know what you are doing. Also, if animals are able to carry the infection and somehow get bit before you kill and eat them...you could be screwed. At least you know plants will always be safe.
When thinking of my friends and family in a zombie out break situation I would have to say that our knowledge of plants and wilderness survival skills would be close to none. Modern society has come so distant from the days of hunting and gathering that I would assume that most people would also be in the slim to none category. I think these skills would only up your chances of survival and I think this is an important when food supplies become scarce and animals could be zombies.
