There is ozone found in two areas. One is in the upper
regions of the atmosphere and the other area is the ground level. They are both
made up of O3, but the ground level is made from chemical reactions of nitrogen (NOx) and volatile organic compounds
(VOC). Both of these chemicals mostly come from the burning and evaporation of fossil fuels like gasoline, natural gas, and coal.The ozone in the upper regions of the atmosphere protects us from
the harmful rays from the sun, but the ground level ozone is the main reason
for smog. The ground level ozone is very harmful to elderly people, young
people, and people with respiratory problems. It can also contribute to
producing a respiratory problem. The ground level ozone is also harmful to sensitive
vegetation and ecosystems, including forests, parks, wildlife refuges and
wilderness areas.
