Was reading Colin Beavan’s top ten eco-lifestyle changes and (having recently gone to lunch with some Jewish friends on a Saturday) particularly like this one:
3. Observe an eco-sabbath. For one day or afternoon or even hour a week, don’t buy anything, don’t use any machines, don’t switch on anything electric, don’t cook, don’t answer your phone, and, in general, don’t use any resources. In other words, for this regular period, give yourself and the planet a break. Keep your regular eco-sabbath for a month. You’ll find that the enforced downtime represents an improvement to your life.
Though I would find it tough, for sure, especially staying off the computer!
