If Fluther was trapped on a deserted island, how could you help?

Stop right there! What do you have on your person right now? Stuff in your pockets is all that counts… not the satellite phone or solar GPS I’m sure you have on your desk.

Ok?

Now imagine that you are stranded with whatever you have on and whatever is in your pockets on a deserted island with every other Flutherite how we got there in the first place isn’t important and we all have… say… 6 months until rescue arrives. What skills would you be able to use to help the group or yourself survive? How good are you with as Theodore Roosevelt roughly said doing what you can with what you have where you are? Could you survive without the conveniences and luxuries of modern civilization? Would interpersonal conflict eventually lead us all to starve to death or kill each other?

Right now I have a flashlight, a knife, my keys, and my phone. The phone would be about useless. The knife would only stay sharp for so long, and the batteries on the flashlight would eventually die. The stuff on my keychain would probably have some limited use. I also have some pretty decent outdoor survival skills.

What about you Fluther? Could all of us on a large, deserted island survive with what we have on us at this moment for 6 months without fictionalizing and killing each other off?
