The now scrapped plans for a third runway at Heathrow sparked fierce debate about air travel. Anti-flying groups opposing the plans, mostly cited environmental concerns. While many are concerned about the impact airport expansion will have, others worry that restricting our freedom of movement is a backward step. Regular air travel has only recently become affordable for most people, and critics argue there is a heavy dose of snobbery in the dismissal of cheap flights. So is there more to the fight over flight than concerns about carbon emissions? Is the freedom of flight now a necessity to be defended, or a luxury we should sacrifice for the good of the planet? This Battle of Ideas debate filmed by WORLDbytes volunteers is revealing.
