This was my initial thought too. Like if I grow a bunch of nice smelling flowers, and crack open a window during the spring. Am I worse or better off than purchasing a scented candle.
Should we as a species stop nice smelling things entirely.
The sub-species that I belong to does stop smelling those nice things entirely as my nose clogs up, eyes water, and convulsions known to many as "sneezing" take over my body.
Imagine how much “air pollution” one inhales when taking a big whiff of a nice curry.
No, but I wouldn't complain if we stopped scenting every damn cleaning and hygiene product. Please, no scented hand soap, or laundry detergent, or especially dish detergent. I'm not gonna complain if people want scented conditioner, but you probably don't need scented shampoo if you're going to condition anyways.
Intuitively I'd guess the scented candle is worse than the flowers. I doubt soot and vaporized wax are good for you.
