well, you see when we burn gasoline it turns into carbon. when theres a lot of cars, people (ie. look at photos of a crowded street in china) wear masks to filter some of the carbon from entering their lungs, imagine the entire globe consisting of roughly 50 billion people used majorly flying vehicles using xenon fuel to travel, and every single "town" consisted of skyscrapers and more glowing signage adding to the amount of xenon, argon and neon signage, practically everyone would have to wear a mask of some sort to prevent poisoning from these gases.
