Thousands of people from around the world have converged on Rio de Janeiro this week for the Earth Summit, a mammoth conference aimed at creating a green economy for the globe. But I can count on one hand the people who got here by bicycle. One finger, actually.

Naomi Devine, a 33-year-old Canadian sustainability planner, rode her bike here from Vancouver, British Columbia. Well, she rode a lot of it, anyway — and the rest of the time, she rode mass transit. She says she caught a train from Eugene, Ore., to San Francisco “because it was winter at the time,” and bused from Mexico on. Nonetheless, she estimates she rode about 1,000 miles. It was an incredible, crowd-funded journey, done the hard way (in contrast to this writer, who flew from Seattle to Dallas to Rio, and thought that was a long day).
