Presentation transcript:

Essential Questions: 1) What role have humans played in the destruction of the Ozone Layer? 2) Why should humans be concerned about the destruction of the Ozone Layer?

What is the Ozone Layer? Ozone is a chemical found in the upper atmosphere that protects the earth from the sun’s harmful UV Rays.

What are chlorofluorocarbons? Found in aerosol cans Refrigerator Emissions Air Conditioner Emissions CFC’s

What is the problem with using CFC’s? They create holes in the ozone layer around earth. This layer prevents UV radiation from reaching earth.

How can UV radiation affect living things? Mutations Skin Cancer

Global Warming vs. Ozone Layer Depletion More UV radiation Caused by air pollution Melting of Ice caps Mutations CFCs CO2
