Depends on why transportation was disabled. That doesn't happen on its own and more likely whatever created the transportation problems is a much larger concern. Your top three most probable large scale scenarios are nuclear fallout, biological contagion, and military occupation. Each one would alter how you'd need to react since your food sources and how you would gather food would likely be affected.

Many strategists will tell you that a perfect plan doesn't exist and a perfect execution is even less likely. The three areas you need to be concerned about are your ability to gather food/water, your health, and self defense. Food is important but it's not separate from the others in a survival scenario. Being able to adapt to the circumstances and adjust as needed is vital.

Your concerns are in order as follows:

1. Self Defense
2. First Aid
3. Potable Water
4. Gathering Food
5. Base of Operations
6. Fortifying your new home
7. 3-6 month supply of 1-4
8. Building a Community

I garden now and know quite a bit about edible plants. Would I kill animals, only if necessary. I eat mostly vegan now. I know a bit about animal care, I am sure I could raise and milk cows and chickens. I will eat eggs and milk products on occasion, I can also sew, make soap, i know how to dry foods and can if necessary. I know how to gather water from dew, and I know how to distill it if necessary. Being alone I'd have some problems, but I think with all my kids we may have skills to get by for a while

I doubt I’d live very long, but some younger people would. The question is for how long, and if they could raise families.

I live on a small farm, but my gardening relies on fuel and machinery. Let’s hope nothing like that ever happens.

Right now my freezer is full of deer, prawn and salmon I caught/hunted. Crab I like to eat fresh. I stopped gardening and canning and freezing due to time. So ya it would take an adjustment but I could make it here in BC. Longer winters and no ocean not so confident

Yes, I could. I've had practical experience with it, having lived in bush Alaska.

Yes, I can survive nicely. Lacking my meds would be the bad part, but I think I might be able to make it through that as well.

Id be eating lotsa fish !

Without a doubt, yes. If I lost all the weapons I have, I have skills to make more, as well as traps snares and booby traps if needed. But if I have food, hopefully the boobies will come to me on their own. (couldn't resist, sorry) I know several ways to make fire without a bic lighter, and where to gather water and filter it.
Too many worry about food and water first but depending on the weather, shelter might be your first priority. You need to remember the rule of threes. Breath first, without air you can suffocate in three minutes. Shelter, in the cold, you can freeze to death in three hours. Water, you can last three days without water. Food, you can go about three weeks without food.

As a Marine, I took a number of environmental survival schools. I feel I could do pretty well. I can fish and hunt, so I can provide a steady source of protein. The real issue in survival is water. You can go many weeks without eating. You can't go more than about two days or so without water.

I can sail. I'd just steal a boat.

I’d be a goner once my insulin runs out. Coma. Gone. Everyone else can fight over what’s left.

Yes, I've been studying plants all my life & know the edible ones. I also have chickens & goats. Would they count? I don't eat meat so getting enough calories in the long run could be an issue. One thing I've never done is grind acorns into meal & soak the tannins out to make them edible...that was the staple of the Native Americans in my area.

Would start a pile to bring bugs we are squeamish about bugs in this country bugs are the best source of protein. Lots forget about roots most roost are edible take a potato it is a root yet it's plant is deadly nightshade. Even though wood is not the best form of nourishment it can sustain you until better food can be located. Even in the driest condition water can be pulled out of the air with a proper still.
