What is the history of ozone?

Answer 1

Ozone was found in 1880. It protects us from harmful UV rays.

Answer 2

Ozone was first identified in the mid-19th century, with its unique smell noted during lightning storms. In the early 20th century, scientists discovered its ability to absorb UV radiation in the upper atmosphere, forming the ozone layer. Ozone depletion due to human activity, such as the use of chlorofluorocarbons, became a major environmental concern in the late 20th century.
