What is the main environmental concern associated with the use of chlorofluorocarbons (CFCs)?

Correct Answer: Ozone layer depletion

Step 1: Understand what chlorofluorocarbons (CFCs) are. They are chemicals used in products like refrigerators and aerosol sprays.
Step 2: Learn about the ozone layer. It is a protective layer in the Earth's atmosphere that absorbs harmful ultraviolet (UV) radiation from the sun.
Step 3: Know that CFCs can reach the upper atmosphere where the ozone layer is located.
Step 4: Realize that when CFCs reach the ozone layer, they break down and release chlorine atoms.
Step 5: Understand that these chlorine atoms can destroy ozone molecules, leading to a thinner ozone layer.
Step 6: Recognize that a thinner ozone layer allows more UV radiation to reach the Earth's surface, which can cause health and environmental problems.
