Hypothetical survival situation: what do you bring?

You're on a survival gameshow where you'll be moored on an island for one month. You have access to any and all natural resources available to you on the island. But you can only bring three (3) resources with you to start. What do you bring? And why? 

I'll start:

1. a tarp: for shelter, carrying items
2. fishing line w/hook: hook for fishing and fishing line for traps
3. a flint stick: for starting fire
