Explanation:

Ground-level ozone is involved with smog formation, not ozone in the stratosphere.
While tropospheric ozone is considered a greenhouse gas, stratospheric ozone is not thought to have a significant effect on global warming.
Decreasing levels of stratospheric ozone result in increased levels of ultraviolet radiation reaching the ocean, which may inhibit phytoplankton photosynthetic activity in surface waters.
The increased levels of ultraviolet radiation can also negatively affect human health.
THINK!
•What are the difference between ozone in the stratosphere and ground-level ozone?
•Why ground-level ozone are formed or why ozone is stratosphere is decreasing?
•Ozone related conventions and protocols.
