Bamboo is the hot new ’sustainable’ material because it grows ultra-fast (it’s a grass) and it can be used for everything from building materials to fabrics. And it’s very attractive, durable and cost-efficient. So what’s not to like? Nothing unless this stuff is traveling thousands of miles to reach an end-user. This is a major dilemma of the carbon economy.

I don’t buy a lot of organic products in spite of a commitment to cutting the use of chemical fertilizers and pesticides. Why? Because the last quart of organic milk I bought traveled all the way across the US before it got to me. There is a balance to be determined between environmentally beneficial labels like ‘organic’ and ‘fair trade’ and the carbon cost of some of these products above and beyond their other benefits.

I’ve had basic discussions with the optimistic 21st century hippie types who run my local holistic food store and it’s not a comfortable conversation. If you imply that organic milk may actually be bad for the environment if it comes from Oregon and you live in NY, you’re treading in religious belief territory for many folks who’ve been fighting the good fight for a long time.

Unfortunately, carbon cost is now another factor in making buying decisions if you are a responsible consumer. And BTW, buying used and local is a great way to limit carbon costs if you need stuff.
