So, are you a green or are you a supporter of completely free migration? Because it seems to me at least that you cannot be both. You're either in the Gatwick camp or the Heathrow camp. Make your choice.
You can clearly be Green and against borders, travel doesn't have to use huge amounts of oil, for example listen to last week's Low Carbon Show on low carbon footprint travel:
The Low Carbon Show: #13: Slow Travel
Cargo Ship, Train & Milkfloat
Like Slow Food, Slow Travel is about quality rather than speed. Dan Kieran talks about his journey across Britain in a milkfloat and LoCO2 founder Jamie Andrews talks about travel by cargo ship and train travel in Europe.

My personal suggestion would be renewable powered airships, but first capitalism and war have to be stopped, the US military uses as much oil as Australia does in a whole year in just two days.
