CFC's are responsible for destroying the protective ozone layer in Earth's atmosphere. But the use of a CFC alternative in air conditioners and refrigerators would make the devices more expensive, and they may not cool as well.

Ozone can be either beneficial or harmful to people depending on where it is in the environment.

Pretend you are a manager of a nature preserve that contains rare trees scientists want to cut down in order to obtain a lifesaving drug. The trees are endangered, and disturbing the area might also endanger several endangered animals.
