Highly wishful, unrealistic answer: How about getting kids to walk to school? Let the carpool drop the kids off a block from the school.

We are taught, “According to the effort is the reward.” Children right away pick up on the idea that when something takes effort and commitment, that means that it’s real. Take the Mitzvah of Tzedaka, charity. I’ve taught Jewish children from all kinds of backgrounds, and they get the idea of Tzedaka — I think that is because they understand the value of money, and that it’s going to hurt a little when they have to take some of their money and give it away. To really connect kids with the environment, it I think it should involve something where they have to sacrifice — whether it’s their time, their money, their efforts.
