I don’t see where you get that implication. Perhaps they’re spending a month in France rather than taking three one-week trips. Perhaps they’re living closer to town so that they don’t drive as much to get to work and their local hacker club. There’s lots of ways you can reorganize your life to be less resource-intensive without meaningful sacrifice, especially if you’re starting from the immensely wasteful late-20th-century-middle-class lifestyle.

It's one of the best decisions I've made. I have more adventure, culture, cuisine, and other values I used to get from travel, without the pollution and emissions.

I posted about it here -- https://www.inc.com/joshua-spodek/365-days-without-flying.ht..., although my views have continued to evolve since then -- and on my blog.

I haven't been in a plane myself in 4 years. I got months without getting in a car. I'm up to my ears in adventure.

But it's not enough, right? We're completely dependent on cheap sources of fossil fuels to drive our economy. How much carbon is released in the atmosphere from just me eating food?

Ah yes, life without flying must be so dull. Is that what you're implying? Seems rather silly.
