Imagine if every Shabbat most Jews took a rest from using their cars? I assume it might do some good for the quality of our air. No need to wait for Yom Kippur once a year & no need to have "no economy". We can be a totally modern & productive state & observe the Shabbat. Anyone who lives in Israel can see that what this place needs is to "chill". and not in the frenetic way people chill - cafes, discos etc. There may be a place for that as well....but Shabbat is something different. Shabbat = a total mental & spiritual rest. I think we'd all see many benefits from more Shabbat celebration here. Mental, spiritual.....and even cleaner air maybe.
