IMPORTANT

Chlorofluorocarbons (CFCs) were created in 1928 and were used in products such as aerosol propellants, cleaning solvents and refrigerants. It has since been proved that CFCs contribute to the destruction of the ozone layer. They continued to accumulate in our atmosphere until a global decision was made to address his potentially catastrophic issue.

A graph that contains two sets of trends, like this one can be referred to as a piecewise relationship.

Use the graph to determine whether the global agreement to ban CFCs was successful? Explain your answer.

A graph that contains two sets of trends, like this one can be referred to as a piecewise relationship.

According to the graph, what was the rate of change in CFC concentrations in the atmosphere leading up to the global ban? Verify your answer using different points on the graph. Discuss any discrepancies you may have.
