Tropospheric ozone is harmful, damaging plants and human health while ozone at the stratophere level screens out mutagenic ultraviolet radiation.

Explanation:

Ozone is dangerous and harmful in the lowest layer of the Earth's atmosphere. This layer is called troposphere. The reason why it causes damage to plants and human health it is because ozone is a reactive gas that affects plant synthesis and causes smog (a form of air pollution that is particularly dangerous to sensitive respiratory diseases such as asthma). However, ozone is helpful in the second layer of the Earth's atmosphere: the stratosphere.  It prevents and blocks dangerous ultraviolet radiation.
