After 4 days of NO WATER AT ALL then weeks of collecting water in containers, waiting at the end of the road for the water tanker, queuing for the water, getting (the VERY heavy) water back home...wheel barrows, the kids balanced a bucket on a skateboard, I have a whole new appreciation for water. I had no idea how much we use in a day, and when you try to wash clothes, pots and people as well as drink and cook in the stuff we use gallons and gallons in a day.
My area still does not have clean water, although contaminated water does now flow from the tap, no sewers however (another water use we take for granted in this modern world), we are using a very primal long drop up the garden, even in the dark and the rain.
So...water is heavy, and inconvenient to carry (it slops) and to store. I appreciate we use more in our modern life than we did in paleo times, but even so, given the difficulties of containers...another problem we have had over the last two months and thank you to whoever it was out there who donated the 20L water containers that were distributed at the welfare centre, they have been a God send.....but given all the above I believe that unless our paleo ancestors were deeply stupid, and there is no evidence that they were, they lived very near water.
People who carry water today do so because of the laws governing land. One lives on the land one owns even after a drought (or earthquake) our paleo ancestors would have moved!
Edit: We live in Christchurch NZ. Thank you to all who sent help. We truly appreciated it and we are very grateful.
