Explain why ozone in the lower atmosphere is a bad thing but why ozone in the upper atmosphere is a good thing.

Ozone in the lower atmosphere (troposphere) is a bad thing because it can make health problems occur (problems like hard breathing and asthma) and environmental, while ozone in the upper atmosphere (stratosphere) is a good thing because it protects living things from ultraviolet light from the sun.

Explanation:

Ozone in the lower atmosphere is not emitted directly into the air, and it is created via man-made products (factories, cars, chemical solvents, etc.). When ozone in the lower atmosphere is created, it does not go into the upper atmosphere. Since ozone in the upper atmosphere is above a lot of living things (depending on where the living thing is), it does not cause as many bad effects as ozone in the lower atmosphere, which makes it good.
