Chapter 5: The Hole in the Sky

The article discusses various issues related to ozone hole over Antarctica. The good news is that ozone depletion is an environmental problem that can be solved. But as long as there is an ozone hole over Antarctica each spring, teams of ozone researchers will be there to study it. Most of the world's ozone is found in a distinct layer in the stratosphere, the region of the atmosphere that is roughly between 6.5 and 30 miles above the earth's surface. The main culprits in the ozone destruction story are chlorofluorocarbons. The bodies of Antarctic birds and mammals are well protected from ultraviolet (UV) radiation by fur and feathers. But their eyes may be sensitive to damage by higher-than-normal amounts of harmful UV rays coming through the ozone hole.
