Atmospheric hole. History of ozone layer

Description

Freon was a refrigeration breakthrough in 1928. It took 45 years for scientists to recognize its dangers, and another 15 for the international community to enact a worldwide ban on all CFC gases. This program illustrates that long process of problem-solving and political action, focusing on the work of Nobel-winning chemists F. Sherwood Rowland and Mario Molina and how their discoveries led to the 1989 Montreal Protocol-which may well have prevented catastrophic depletion of the ozone layer. Interviews with Rowland, climatologist Robert Watson, and EPA official Stephen Anderson illuminate one of the most important environmental sagas of the last century.
