Nic is also absolutely right; airplanes are far more polluting then any other form of transport, despite carrying so many passengers. You also have to remember that luxury goods like television serve little purpose, yet consume quite a bit of energy. A car, however polluting, at least has an actual purpose.
If you should see a man walking down a crowded street talking aloud to himself, don't run in the opposite direction, but run towards him, because he's a poet. You have nothing to fear from the poet - but the truth.
