I started thinking about our survival needs, from what came the important question: why are we not more careful on what we do on the planet, when it is what offer us the possibility to live?
Our survival needs are:
– appropriate atmospheric pressure
We can survive:
– 3 min without air
– 3 hours without a regulated body temperature
– 3 days without water
– 3 weeks without food
The one I am the most interested in is the water. Maybe because it is my favourite element to be in and my favourite drink 🙂
Our body is composed between 60% and 80% of water. It (water) provides the environment necessary for life.
A sandglass is meant to give the time like it is indefinite, but what if it was leaking ?
I am thinking to make one with water. The amount of water inside would be equivalent on the volume available on earth/per person, and would leak in accordance of the diminishing of the resource.
