Mike:

For a specified amount a time ?

What is the gender age and weight of the person?

Are they carieng for themselves or are there others involved?

What is the region they will be in?   Climate cam play an important part.

For me… by myself… with a good knife and a full pack, I’m good forever.

You ask why?  Because God is on my side

Rick:

A good friend of mine has answered this by saying, “Brown eyes, big thighs, and Budweiser”  (but he’s been know to exaggerate.)

Ed:

Peace of mind

Now, in order to achieve PEACE OF MIND,  what we need is balance across the globe.  No need in this time for anyone to be thirsty or hungry.  To sustain what is  most important is to just keep it clean!  In order to keep it clean, greed in this world has to end.

Leroy:

Not possible.
ie how long?
and who’s gonna take it away from you?
Love is all you need.

Dr. IQ:

Sleeping under open skies and eating barley bread is ample for every soul who will taste Death…  Period !

My list  for sustaining life –
 
1. People need people, well at least for some.
2. Water
3. Food
4. Air
5. Healthy Body, skin.
6. Nature and a good play-mate.

Ah ha!  I was wondering if anyone was going to bring up reproduction being necessary for sustainability?

Mom:

Somewhere years ago I had to memorize a “Hierarchy of Needs.” I think it
might have been in psychology class at Ursinus.

Maslow’s Hierarchy of Needs

The list of needs is order like a pyramid.  At the base of the pyramid are physiological needs – 

Breathing
Homeostasis
Water
Sleep
Food
Excretion
Sex
Clothing
Shelter
