Summary:
The importance of the ozone layer, the invisible layer that protects Earth's atmosphere, is the focus of this program. Ozone molecules are examined, and the need for an oxygen/ozone balance in the atmosphere is explained. The Earth at Risk Scholars measure UV radiation and examine ozone by creating static electricity. Mario Molina, an atmospheric chemist at MIT, discusses the hole in the ozone layer over Antarctica and the gradual depletion of the ozone caused by the accumulation of gases like methane in the atmosphere, the combustion of fossil fuels and plastics, chlorofluorocarbons from refrigerators and spray cans, and nitrous oxide from fertilizers. Part of The Earth at Risk Environmental Video Series that examines the threats facing Earth and the environment.
