Water

Something to think about, stemming from a Bible study presented by Prof. Steve de Gruchy at Conference:

3% of the world's water is fresh water;
0.1% of this water is surface water;
About half of this water is accessible;
It takes more water to produce the plastic bottles which are used for bottled water than the water it contains;
People need about 20l of water, where most of the world's population have to survive on 4l per day.

How do you use water?
