HOW COULD I SUR­VIVE BE­ING WASHED UP ON A DESERT IS­LAND?

BBC Earth (Asia) - - Science -

1. WA­TER

You can only sur­vive three days with­out wa­ter.

Scav­enge the beach for con­tain­ers and set each one in the sand, at the bot­tom of a wide, shal­low pit. Line the sides with palm leaves, ar­ranged so that rain drips into the bot­tles. While you wait for rain, ex­plore the is­land to

look for streams.

2. FOOD

Co­conuts are a great food source. Wedge one on the ground, with the pointed end fac­ing up­wards. Find the largest rock you can lift and drop it onto the coconut to break the husk fi­bres apart. One sur­vivor of the 2004 tsunami ate noth­ing but co­conuts for 25 days be­fore be­ing res­cued. So

your chances are good!

3. SHEL­TER

Un­less you can sleep, you will lose the abil­ity to con­cen­trate, plan and stay mo­ti­vated af­ter just one or two nights. A bun­dle of small branches spread on the ground and cov­ered with palm leaves is still bet­ter than sleep­ing di­rectly on the sand. Af­ter that, build a low bed frame by ty­ing to­gether

saplings.
