WebOzone acts as a shield protecting us against harmful ultraviolet radiation from the Sun. However, ozone at ground level is a pollutant. It can trigger breathing difficulties and damage plants and crops. It is one of the principal ingredients of smog. Therefore, whether ozone is good or bad depends on its altitude in the atmosphere. http://www.nishkatuts.com/class12/chemistry/pblockelements.html
