Continuing a discussion that started here.
You keep saying I am wrong but you don't say why. Do you even know how much of what type of food source would be required to feed a 100 people. You asked for example and I gave example, one that I have exacted many times. On paper it's fairly simple: 3 ways to get fish, 3 ways to get fur, 3 ways to get feathers. This is the range of vocabulary for problem solving the issue of feeding a group of people.
This is also based on a group to self regulate and not overgraze an area and it assumes the group is not under attack from outside source.
You posted this in reply to a question of where you would get the 300,000 kcal a day needed to feed 100 people.
Plan A: conserve calories and use hook and line. If this does not yield enough fish for a 100 people, and it probably won't, then plan B requires the expenditure of calories in which case get in the water and hunt the fish down....with extreme prejudice. This has a greater yield anyway. That's just one example.
Is your fort near a mighty river or great lake? A brook or stream isn't going to have enough fish to feed 100 people. The proposal that the 100 fishermen go wading in the water (presumably) spearing fish is comedy gold. If they're supposed to grab fish the way hungry bears do even better. For comedy.
Admit it, until now you never gave a moment's consideration to the practical problem of feeding 100 people.
I have done more than consider, I have put to practice. I have considered the the task of waste management in which case I think you are the man for the job.
How many people have you kept fed for a month living entirely off the land and water at your doomsday retreat?
If you care to continue this conversation then start another thread.
Done.
