I don't necessarily get this organic living thing. But I do know the difference between talking about something, and actually living it.

There is talking the talk, which for some people, means spewing a lot of hot air and pollutants:

Environmental crusader David Suzuki finally got out of his diesel-fuelled, pollution-spewing, greenhouse-gas-emitting bus yesterday and actually pedalled a bicycle during the Victoria leg of his cross-Canada eco-tour.

But don't start polishing up the Nobel Prize just yet. Suzuki only biked one measly kilometre -- and it was the very last kilometre of his entire 50-city tour to biot.

Final tally: 7,204 kilometres by bus, one kilometre by bike. An estimated 20 tonnes of global-warming carbon dioxide belched into the atmosphere.

And then there is walking the walk, or in this case, running the 260 miles:

This year, Nomadik.com is celebrating Earth Day with Steve Shriver, founder of Eco Lips, organic fanatic and athlete extraordinaire. He's planning to run ten full marathons in ten days - all in support of organic living.

"The running will only be about fours a day," says Steve, "and we'll spend the rest of the time spreading the word about organic living." His clothing and food for the entire journey will be organic, and Steve will stop at schools, organic farms and stores along the way to teach people about organic sustainability. And we'll be right there with him, cheering him on to success.

On April 12 Steve will launch the first ever Organic Endurathon by running 10 full marathons in 10 days. What’s so special about running 260 miles? Aside from the fact that we’re supremely impressed anyone can actually do this, Steve will do it all organically. His clothing, food and general lifestyle are all organic and Steve is paving his own campaign trail to raise awareness. It’s not only possible, it’s downright easy to be good to the earth and good to your body at the same time.

Not sure that it's so easy, but I'd sooner listen to Steve Shriver's green pitch than David Suzuki's. Credibility has no colour.

Organic clothing? Hmmmm -- let's hope we're talking something a bit more modest than fig leaves.
