Ight, so have/get a vegetable&fruit garden, so that will help. Next, you can make a fish trap out of a plastic bottle(I have a creek by my house and there's a lot of fish there). Here's a tutorial: https://www.youtube.com/watch?v=6yocq6UDZFE . You can order, or try to make, a bow to get squirrels and birds. And you can look under stones and logs for bugs & grubs. And that's my survival plan. Also get honey(not the app but the bee food. But you can also get the app if you want), because that stuff never expires.
Update(4/23/20): Get a cast net. It's another way to catch fish. Update(4/29/20): You can eat tree bark, just use the inner part of it for certain trees.
