7. Shelter: You will need some form of shelter to protect yourself from the elements. A tarp or a tent would be ideal, but you can also improvise shelter from branches and leaves.
8. Sun protection: The sun can be very harsh on a deserted island. Be sure to pack sunscreen, a hat, and sunglasses.
These are just a few of the essential items you should take with you if you are ever stranded on a deserted island. With the right tools and knowledge, you can survive until you are rescued.
