What do you need for living?[edit]
- Air - you can only do a few minutes without it
- Water - you can only do a few hours without it
- Energy (Food) - you can only do a few days without it
- A warm, dry and secure place to live in - how long would you do without it?
These are the main basics and they are all under threat by the not so basic things we consider essential in our modern life.
The way we value energy is a key to making sure we don't loose the basic things.
