"One return flight between Britain and Australia produces more carbon dioxide than an entire British household in a year,: Mr. Adams says, and the industry as a whole produces twice as much as India does in a year.

Furthermore, the fact that the industry crisscrosses a multitude of borders means that the pollution isn't even included in the Kyoto Protocol on greenhouse gases and the fuel isn't even taxed. High altitudes (which are more fuel-efficient) mean that the CO{-2} just takes longer to disperse. As pollution goes, it takes the cake."
