Any drop in ozone level, whether from SSTs (supersonic jets) or CFCs would allow more ultraviolet light to reach the Earth s surface--an effect that holds severe consequences for life on the planet. Exposure to ultraviolet light enhances an individual's risk for skin cancer and cataracts so an increase in this radiation could lead to more cases of such diseases. Ultraviolet light also harms food crops and other plants as well as many species of animals."
According to a Scientific American I read several years ago, the increase in ultraviolet exposure would amount to a New Yorker moving to Atlanta.
Hardly something to get fizzy over.
It kind of makes me wonder how Freon damages the ozone layer when it is heavier than air. And, the only way to destroy the ozone layer is to put out the sun.
