    Now you need to upgrade this too a supermarket and could live for generations provided you have enough people in the store. Then worst would is inbreeding. For instance you could generate your own power using bicycles. Just imagine the possibilities from a Walmart or a target. Some even an automotive department, an health clinic and a pharmacy. I heard one that sold caskets/coffins.

    I'm a few minutes into the video, but I don't think he's gonna talk about all the seeds that Evin could've used. Walmart, has spaces in the roofing where it allows a good chunk of sunlight to come through. I've seen other smaller grocery chains in my area with similar set ups. Evin could EASILY start his own self sustaining farm, all the farm tools, dirt, and instructions to do so. Are in the gardening section of the store. Not to mention pots, pans, and other things to hold plants. Regardless of the food that spoils, the only thing Evin would have to worry about is Water, and Winter. However, he could easily substitute water with juice from the different fruits and vegatables he's growing. All that human waste and food leftovers? GOES right into fertilizing the soil. I get for the sake of the question, he HAS to eat the food in the store. But nobody said he couldn't just grow his own in the right store. Especially if that store has windows to collect water, or GROW PLANTS.

    This is all good if he is the only one around. Pretty sure in the early days of the apocalypse people will be emptying the supermarket. Look at what happened with Coronavirus. I still love your optimism. Even if Evan was alone and could prevent anyone from access the supermarket completely, you are going on the theory that he would have the survival skills to know how to cure and smoke meat, make a compost garden and know how to work out the prevent of food spoilage. Ironically thanks to the invention of supermarkets a lot of people in the world have become lazy in how we get how food and how it is prepared. You should do one on How long you could survive in a bunker.

    Uhh, I think you need to do the basics first. Water. Specifically, clean water. Rain water spoils over time (about a week), meaning collecting them in certain days won't save you, esp since depending on where you live, it may not rain for months. So unless you have some way of filtering the water which you collected, you're not gonna last one year. And drinking spoiled water will result in you losing more water than gaining water.

    What about radishes? I’m told they have a good multiple cycle, are easy to grow, and and have a lot of much needed nutrition, even over potatoes. Also I learned from this I need to learn to make dehydrated foods, how to smoke meats and fish, and also how to garden in a way that maximizes my crop yield (and learn how to dry mushrooms for long term usage). And it might be important to attempt to get roof top access (which is possible, I worked in one) from inside. This means that further important crops can also be harvested and rain barrels can be set up. This is assuming the being locked in doesn’t mean locked in but just unable to get out and away from building. Yeah I know you said soil is important to consider but the compost can work better being outside and properly treated by the wildlife that can access the roof top. would honestly be smarter for his health (due to diseases) to....just use the roof to do his business over the edge of so it isn’ his living space....anyway. Sorry for the tangent m. Thanks for the video! Food for thought and something to consider for story ideas!!
