I'd like to read a survival guide based on actual locations rather than old boy scout tricks.

If you strand on a deserted island in the year 2026 you will find a heap of plastic bottles and other trash that can be made into a solar powered distillery or desalination device. It might still be full of micro plastics but whatever so is the the bottled water in the grocery store.

Actually if you ever get in a survival situation besides falling off a ship, your best option is probably to rob the nearest grocery store. It's a great resource that can be found in the most desolate places.
