Your second point is a separate issue - it's more practical to get people to fix the things that can be fixed before asking them to change the way they live and go back to this unrealistic ideal world of no machinery etc.
When you consider that so many people (in Sydney, where I live) commute to work on their own in their cars, and that every 30 of those cars could be replaced with one bus, you can only conclude that it's madness.
Similarly that we're still using incandescent bulbs. Or that many office buildings leave their lights on 24 hours a day. Or that people here run air conditioners 6 months of the year (we are not living in the tropics - I'd say there's probably 10 days a year here where aircon is necessary for any healthy adult - obv the sick or the elderly are another story).
Everywhere you look there are gross inefficiencies, things that could be fixed with a little planning, expenditure, collaboration, and compromise. It saddens me that we seem to be too selfish and disorganised.
The difference between a car and a bus to me is the difference between the internet and cable television. With the former, you get what you want when you want it. With the latter, you have to go along with the group and rely on others to decide for you.
