George Monbiot, author, writer for The Guardian: If our airports are full, there’s an immediate solution. Fly less. The Free Ride campaign has proposed a just means of achieving this: curb demand by taxing frequent flyers, but not those who seldom fly. (In case you’re wondering, I limit my flying to once every three years). But reason has taken flight, the moral compass spins, greed and desire soar towards the stratosphere, and our conscience vanishes in the clouds.
