The ozone hole doesn’t stop the radiation which is harmful to living things on earth and causes harmful effects such as health problems like skin cancer and eye damages.
What gases are in Ozone?
Ozone is a gas made up of three oxygen atoms (O3). It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). Ozone protects life on Earth from the Sun’s ultraviolet (UV) radiation.
What are the sources of ozone?
Ozone in the Troposphere . The two major sources of natural ground-level ozone are hydrocarbons, which are released by plants and soil, and small amounts of stratospheric ozone, which occasionally migrate down to the Earth’s surface. Neither of these sources contributes enough ozone to be considered a threat to the health of humans or the environment.
