Investigation 2: The loss of stratospheric ozone: where are people at risk?
|Extensions and Enrichment||
In this investigation, students learn about the recent declines of ozone concentrations above Antarctica and the Arctic. These facts pose the risk that unusually high amounts of harmful ultraviolet radiation will reach Earth's surface and threaten life, especially in the high latitudes. Students learn how human actions have affected the natural geography of stratospheric ozone, they estimate populations at risk from ozone destruction, and they learn how international complications obstruct solutions to the problem.
