There was a time when I loved articles like this, supplied by greenmatch.co.uk. It's titled 70 Ways To Save the Planet. But less so now, not because I thing the planet needs less saving, but because I think that what we really need to do is save ourselves.

As I lay out in my second book, "Sustainable You," focusing on a symptom won't necessarily resolve the cause.

This chat with Joel was delayed 30 minutes by a technical fault, but he redeemed all with cogent, sometimes surprising tidbits. Sample: he devoted his bar mitzvah speech to Martin Luther King, in 1965.

This is the fifth in a series of eight posts detailing concepts and attitudes for sustainable personal change. As one would expect of someone maintaining a 155-pound loss for more than 20 years, my examples have to do with food and weight, but their point is to illustrate how anyone can achieve and maintain healthy change. Today’s concept:  “Working together isn’t enough.”

This is the second in a series of eight posts detailing concepts and attitudes for sustainable personal change. As one would expect of someone maintaining a 155-pound loss for more than 20 years, my examples have to do with food and weight, but their point is to provide both concepts and practical steps anyone can take to achieve and maintain healthy change. Today’s concept: “It’s never one thing.”

Over the past 10 years or so, I have involved myself in two discussions professionally: causes and remedies of obesity, and saving the planet from global climate change.

As you know, I've shifted my focus from the part of sustainability that many think of as green to the part that addresses obesity and food addiction. But I still have great fondness and concern for those topics.

When I was actively pursuing them, I found no greater source, or concentration of information, than at the annual Building Energy show put on by the Northeast Sustainable Energy Association.

Honestly, I never heard of a "green" oil change. But my pals over at Mike's Automotive in Somerville say they're offering one now, and I believe them.
