sustainable travel

A travel style preferred by tree-huggers and hippies. Often times, the vegan will immediately declare themselves a vegan, and then declare and try to enforce a sustainable viewpoint on helpless plebs that are still eating that delicious hamburger.

Did you hear about those tree-huggers flying a plane on solar energy around the world? Yeah, neither did I. Apparently that's sustainable travel, it'll never be mainstream though, so it's mostly for hipsters.
