No Volver I am not missing the point,you are. I have never suggested that everyone should go back to the thirties or live in the cinders eating rotting turnips before going to bed with newspaper over them, or that doing that would turn everyone into plaster saints.
I never even mentioned the thirties because I wasn't there! (Though if I repeated things I heard from those who WERE there it would make your hair stand on end) - I am not even demanding that we go back to the forties, fifties or sixties, which I do have experience of. A more frugal life was not a choice then, it was forced upon us, but now material goods are more readily available to more people, so there are more by-products to dispose of environmentally. The details now have changed, but the general attitude of making maximum use of what you do have and being aware of the effects of how you dispose of your waste is the same, from the carbon dioxide in your car exhaust, through the mountain of "disposable" nappies with plastic backing that you consign weekly to landfill to the 5-year-old kitchen that you replace because the black marble top is now out of fashion
What I am saying is that "society" ( an umbrella word for "people in general") needs a can-do attitude instead of a "someone should be providing xxxx for me but I don't need to look after it it" one. Why do they expect to have modern standards of living laid on but not expect to turn off the hot water tap when they have enough water? to have flush toilets that magically remove all the waste but a lot of people still haven't got the message that wet wipes do not disintegrate when flushed and will eventually clog a drain somewhere.
Ordinary people in the 40s didn't know that the population was going to expand as exponenially as it did, or that the world would welcome easy-life, plastic, disposable everything so enthusiastically that the debris will be around long after mankind has become another failed civilisation.
