Ozone is a gas that occurs both in the Earth's upper atmosphere and at ground level. Ozone can be good or bad for your health and the environment, depending on its location in the atmosphere.
So where is ozone good, and where is it bad for life? High in the stratosphere, ozone acts as a protection from UV light. Without this protective shield, all animal life (not just humans) would be more susceptible to cancer, impaired immune systems, and eye problems like cataracts.o where is ozone good, and where is it bad for life?
