Question

What is the difference between the ozone layer and the ozone people shouldn't breathe?

Answer 1

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. If the ozone is close to the Earth and we breathe it in, ozone can damage our lungs.
