For the last few years I've been in a crusade of teaching my family to be environmental friendly...in some areas I've failed, but I succeed in others, like refill 5L water bottle every week from a natural fountain (every week, 9 - 5L water bottle for consumption), this way they reduce the plastic consumption and recognize the value of water.
On my home on wheels, I'll buy another 20L for water, and have a total of 40L for consumption and cooking...the baths will be in lakes (just like old times).
But I realize that people take water for granted, and they don't chance their behavior for nothing...one of the dangerous of our society is taking things for granted.
